The present invention relates to a touch screen, and more particularly to a laminate of materials constituting the touch screen.
Numerous forms of input devices, such as buttons or keys, mice, trackballs, touch panels, joysticks, touch screens, etc., are currently available for performing the operations of computing systems. In particular, touch screens are becoming more and more popular due to their ease of operation, versatility, and declining prices. The touch screen includes a touch panel which is a transparent panel with a touch sensing surface. The touch panel is located at the front of the display screen so that the touch sensitive surface covers the view area of the display screen. The touch screen allows the user to make selections and move the cursor by simply touching the display screen with a finger or stylus. In general, the touch screen confirms the touch and the position of the touch on the display screen, and the computing system can interpret the touch and then perform an action based on the touch event.
The touch panel may include an array of touch sensors capable of detecting a touch event (a finger or other object touching a touch-sensitive surface). Future panels will detect multi-touch (finger or other object touches the touch-sensitive surface at different positions at about the same time) and near-touch (finger or other object is within the near-field detection capability of the touch sensor). , And may be able to identify and track their location. The multi-touch panel is, for example, US Patent Application No. 10 / 842,862, which is pending at the same time by the Applicant, entitled "Multipoint Touchscreen" filed on May 6, 2004, and was published in the United States on May 11, 2006.

In the following description of preferred embodiments, reference is made to the accompanying drawings showing specific embodiments in which the present invention is embodied. It should be understood that other embodiments may be used and that structural changes can be made without departing from the scope of the preferred embodiments of the present invention.
It should be understood that in all drawings and in the following description, the materials, properties and dimensions shown (in mm unless otherwise specified) are merely exemplary and do not limit the scope of the invention. ..
FIG. 1A-1D illustrates various stackups of touch screen sensor panels capable of forming rows and columns on the back surface of a cover glass according to an embodiment of the present invention.
FIG. 1A shows a window 116 that can be formed in a 0.8-1.0 polycarbonate (PC) housing 118. Inside the window 116, there is a laminate capable of forming row and column traces on the back surface of the cover glass. The substantially transparent glass sub-assembly 100 has a front or top surface that can sense when the user touches a window above it, and a back surface opposite to this front surface. The glass sub-assembly 100 is, in top-to-bottom order, a substantially transparent anti-glare (AG) coating 113 (shown as a dashed line at the top of the sub-assembly) (or this is an anti-reflection (AR) coating, or (May be just plain glass or the plastic surface of a window), substantially transparent 0.7 borosilicate glass or aluminosilicate glass, a black mask (limited area), and patterned indium tin oxide formed in rows. Substantially transparent conductive materials such as oxide (ITO) (15-200 ohms / square maximum, with 0.3 lines and 0.030 spaces) and a substantially transparent 0.025 dielectric layer with vias (eg, with vias). Lamination containing sol / gel TIO2) and another layer of substantially transparent conductive material such as patterned ITO (15-200 ohm maximum, with 0.3 lines and 0.030 space) formed as a row. The body. The two layers of patterned, substantially transparent conductive material may have the same composition or different compositions. A black mask (or color mask) can be used to hide electrical interconnects such as metal traces placed in the border area of the touch screen. The dielectric layer can be used as a flattening layer so that one layer of patterned ITO can be formed on top of another layer. These patterned ITO layers and the dielectric layers between them are symbolically shown in FIG. 1A as dashed lines representing pattern 102.
The substantially transparent PET subassembly 106 can be bonded to the glass subassembly 100 using a pressure sensitive adhesive (PSA) 108. One purpose of the PET sub-assembly 106 is to support an ITO 0.188 continuous sheet (up to 500 ohms) that is formed at the bottom of the PET membrane and can be used to shield the glass sub-assembly from the LCD 110, as well as this ITO shield layer. Is to provide a low volume spacing between the row and the column. The glass sub-assembly 100 can form a touch screen together with the PET film sub-assembly 100 and the intervening layer.
The flexible printed circuit (FPC) 104 can be bonded to the back surface of the glass subassembly 100 using an anisotropic conductive film (ACF) (0.003 after bonding). The conductive tape 112 can be used to ground the ITO formed on the bottom of the PET subassembly 106. The 0.125 thick, substantially transparent PSA114 can be used to bond the PET membrane subassembly 106 to an LCD module containing a 0.2 polarizing layer 115 and a liquid crystal 117. The complete assembly can then be mounted on the window 116 of the housing 118. When the complete assembly is mounted on the housing 118, the glass sub-assembly 100 flattens or slightly dents from the top of the window (0.3Z steps).
FIG. 1B is similar to FIG. 1A, except that the PET membrane subassembly 106 is not completely laminated to the LCD module 110. Rather, an air gap 120 can be formed between them, and a ring of Poron 122 can be formed around the touch screen. The air gap allows the touch screen to be easily separated from the LCD module in the event of a need for repair, replacement or upgrade. Anti-reflective (AR) coatings can be applied to one or both sides adjacent to the air gap to minimize reflections and associated contrast ratio degradation.
FIG. 1C is similar to FIG. 1B in that it includes an air gap 120, but can be mounted in an enclosure with an overhang bezel 124. This is cheaper. This is because the bezel 124 can hide the electrical interconnects formed in the boundary area of the touch screen, eliminating the need for a black mask. In addition, the housing can cover the edges of the touch glass, eliminating the need for polishing and gloss steps, which is also inexpensive. The glass sub-assembly 132 is the same as the glass sub-assembly 100 of FIG.
FIG. 1D is a hybrid of FIGS. 1A and 1C, where the overhang bezel 124 allows the black mask step to be eliminated and full lamination can be used (see all layers of PSA108). Note that the total lamination is a mechanically hard and strong laminate, but the benefit of having an air gap is that the parts are separable and replaceable.
FIG. 2A-2D illustrates various touch screen sensor panel laminates capable of forming columns on the back surface of the cover glass and forming rows on the bottom surface of individual PET films according to one embodiment of the present invention.
FIG. 2A shows a window 216 that can be formed in a 0.8-1.0 PC housing 218. Inside the window 216, there is a laminate capable of forming column traces on the back surface of the cover glass and forming row traces on the bottom surface of individual PET films. The substantially transparent glass sub-assembly 234, in order from top to bottom, has a substantially transparent AG coating 213 (shown as a broken line at the top of the sub-assembly) and a substantially transparent 0.7 borosilicate glass or aluminosilicate. With silicate glass, a black mask (limited area), and a substantially transparent conductive material such as a patterned ITO (15-200 ohm maximum, with 0.3 lines and 0.030 space) formed in rows. , Is a laminate containing. Note that the patterned ITO layer is symbolically shown in Figure 2A as a dashed line representing pattern 250. A substantially transparent PET subassembly 236 with a thickness of 0.188 can be joined to the glass subassembly 234 using PSA208. One purpose of the PET subassembly 236 is to support a substantially transparent layer of conductive material such as patterned ITO (75-500 ohm maximum, with 5.0 lines and 0.050 space) formed as rows. , To provide a low capacity layer between the rows and columns. The two layers of patterned, substantially transparent conductive material may have the same composition or different compositions. The glass sub-assembly 234 can form a touch screen together with the PET film sub-assembly 236 and the intervening layer.
The FPC204 can be bonded to the back surface of the glass subassembly 234 using ACF (0.003 after bonding). The FPC226 can also be joined to a row that can be formed at the bottom of the PET subassembly 236 using ACF. A 0.125 thick, substantially transparent PSA214 can be used to bond the PET film subassembly 236 to the LCD module 210, which includes a 0.2 polarizing layer 215 and a liquid crystal 217. The complete assembly can then be mounted on window 216 of housing 218. Note that when mounting the full assembly on the housing 218, the glass sub-assembly 234 can be flat with the top of the window or slightly recessed from it (0.3Z steps).
FIG. 2B is similar to FIG. 2A, except that the PET membrane subassembly 236 is not completely laminated to the LCD module 210. Rather, an air gap 220 can be formed between them, and a ring of Poron 222 can be formed around the touch screen.
FIG. 2C is similar to FIG. 2B in that it includes an air gap 220, but can be mounted in an enclosure with an overhang bezel 224.
FIG. 2D is a hybrid of FIGS. 2A and 2C, the overhang bezel 224 allows the black mask step to be eliminated and full lamination can be used (see PSA208 full layer).
3A and 3B exemplify various touch screen sensor panel laminates capable of forming columns and rows on both sides of a single substrate according to one embodiment of the present invention.
Figure 3A shows a substantially transparent PC (or glass) housing 318 of about 0.9. Joined to housing 318 using 0.100 substantially transparent PSA308 is a laminate capable of forming column and row traces on both sides of a single substrate. The substantially transparent glass sub-assembly 338 is in a top-to-bottom order, for example, substantially like a patterned ITO (15-200 ohm maximum, with 0.3 lines and 0.030 space) formed as a row. Patterned ITO (75-200 ohms maximum, 5.0 lines) formed as rows with transparent conductive material and substantially transparent 0.7 borosilicate glass or aluminosilicate glass or chemically fortified soda lime glass And a laminate containing a substantially transparent conductive material, such as (with 0.050 space). The two layers of patterned, substantially transparent conductive material may have the same composition or different compositions. The patterned ITO layer is symbolically shown in Figure 3A as dashed lines representing patterns 319 and 350.
The FPC330 can be joined to the back row of the glass subassembly 338 using ACF (0.003 after bonding), and another FPC (not shown in Figure 3A) can also be attached to the front or top of the glass. Can be joined to a row. A 0.100 thick transparent PSA314 can be used to join the glass subassembly 338 to the LCD module 310, which includes a polarizing layer 315 and a liquid crystal 317.
FIG. 3B is similar to FIG. 3A, except that the glass subassembly 338 is not completely laminated to the LCD module 310. Rather, an air gap 320 can be formed between them, and a ring of Poron 222 can be formed around the glass subassembly 338. An AR film or coating can be applied to the back surface of the touch glass and the front surface of the polarizing body to minimize optical loss.
FIG. 3C is similar to FIG. 3A, except that a passivation layer 301 is formed between patterns 319 and PSA309 and between patterns 350 and PSA314. The passivation layer 301 can be formed from silicon oxide and can act to prevent the acid of PSA from eroding the patterned ITO. The passivation layer 301 also physically protects the ITO and metal layers from other corrosive substances, such as sweat from the assembly operator during the manufacturing process, while also physically protecting the ITO and metal layers from scratches during assembly. Can be protected. The use of a passivation layer between the ITO pattern and PSA is shown only in FIG. 3C, but the passivation layer is used with the ITO or metal and PSA in any of the embodiments illustrated and described herein. Please understand that it can be formed in between.

One or more processors 1802 includes, for example, the ARM968 processor, or other processors with similar functionality and capabilities.

Peripheral device 1804 includes, but is not limited to, random access memory (RAM), or other form of memory or storage device, watchdog timer, and the like.
Panel subsystem 1806 includes, but is not limited to, one or more analog channels 1808, channel scan logic 1810, and driver logic 1814. The channel scan logic 1810 can access the RAM 1812, autonomously read data from the analog channels, and control the analog channels. This control involves multiplexing a row of multi-touch panel 1824 to analog channel 1808. Further, the channel scan logic 1810 can control the driver logic and the stimulus signal selectively applied to the rows of the multi-touch panel 1824. In certain embodiments, the panel subsystem 1806, panel processor 1802 and peripheral device 1804 can be integrated into a single application specific integrated circuit (ASIC).
The driver logic 1814 can provide multiple panel subsystem outputs 1816 and form a proprietary interface to drive the high voltage driver 1818.

Host processor 1828 can also perform additional functions not related to panel processing, and program storage device 1832 and display device 1830, such as an LCD for providing a user interface (UI) to the user of the device. Can be combined with.
As described above, in certain embodiments, the multi-touch panel 1824 comprises a capacitive sensing medium in which a plurality of row traces or drive lines and a plurality of column traces or sense lines are separated by a dielectric. In certain embodiments, the dielectric material is transparent, such as PET or glass. Row and column traces can be formed from a transparent conductive medium such as ITO or antimony tin oxide (ATO), but other opaque materials such as copper can also be used. In some embodiments, the row and column traces are perpendicular to each other, but in other embodiments, other non-orthogonal directions are possible. For example, in a polar system, sense lines are concentric circles, and drive lines are radial lines (and vice versa). Therefore, the terms "row" and "column", "first dimension" and "second dimension", or "first axis" and "second axis" used herein not only include orthogonal grids. It should be understood that it is intended to also include intersecting traces of other geometric configurations with first and second dimensions (eg, concentric circles and radial lines of polar coordinates).
At the "intersection" of traces, where the traces pass above and below each other (but do not make direct electrical contact with each other), the traces essentially form two electrodes. Each intersection of the row and column traces represents a capacitive sensing node and can be seen as a pixel 1826, especially when the multi-touch panel 1824 is seen as capturing a "picture" of touch. It is useful. (In other words, after the panel subsystem 1806 determines whether or not a touch event is detected in each touch sensor of the multi-touch panel 1824, the pattern of the touch sensor of the multi-touch panel in which the touch event occurs is a touch "image" (for example, It can be seen as a pattern of finger touching the panel).) When the two electrodes are at different potentials, each pixel has a unique self or mutual capacitance formed between the row and column electrodes of that sensor. Can be done. For example, by exciting a row electrode with an AC voltage of a characteristic frequency, when an AC signal is applied to one of the electrodes, an electric field and AC or signal capacitance can be formed between the electrodes, which is called Csig. Will be done. The presence of a finger or other object in or near the multi-touch panel 1824 can be detected by measuring changes to Csig. A row of multi-touch panel 1824 can drive one or more analog channels 1808 in the panel subsystem 1806. In one embodiment, each row is coupled to one dedicated analog channel 1808 . However, in other embodiments, the columns can be coupled to a small number of analog channels 1808 via analog switches.
The above-mentioned touch screen laminate can be effectively used in the system of FIG. 18 to provide a space-efficient touch sensor panel and UI.
