Embedded display touch structure
This creation is about a structure of a display screen with a touch panel, especially an embedded display touch structure.
Modern consumer electronic devices are often equipped with touch panels as one of their input devices. Touchpads can be classified into resistive, capacitive, sonic, and optical based on different sensing principles.
The conventional touch-sensitive flat-panel display directly superimposes the touch panel and the flat-panel display up and down. Because the superimposed touch panel is a transparent panel, the image can penetrate the superimposed touch panel to display the image. Then use the touch panel as the input medium or interface. However, this conventional technique requires the full weight of a touch panel to be added when superimposing, which greatly increases the weight of the flat-panel display, which does not meet the current market's requirements for thin, thin and short displays. When directly stacking the touch panel and the flat-panel display, not only the thickness of the touch panel itself is increased, and the light transmittance is reduced, but also the reflectance and haze are increased, which greatly reduces the quality of the screen display.
In view of the aforementioned shortcomings, the touch-sensitive flat panel display is changed to embedded Touch technology. The current main development direction of embedded touch technology can be divided into two technologies: On-Cell and In-Cell. On-Cell technology is to fabricate the sensing electrode (Sensor) of projected capacitive touch technology on the back of the color filter (CF) of the panel (that is, attach the polarizing plate surface), and integrate it into the structure of the color filter . In-Cell technology puts the sensing electrode (Sensor) into the structure of the LCD Cell. Currently, the main sensing methods used can also be divided into three types: resistive (contact) type, capacitive type and optical type. Among them, the resistive type uses LCD Cell. The conduction of the upper and lower substrate electrodes calculates the change in voltage partial pressure to determine the contact position coordinates. On-Cell Touch's technology is to first make the sensor of the touch panel on the film, and then attach it to the glass of the upper substrate or directly The Sensor is made of transparent conductive material on the substrate.
The Out Cell Touch technology is to hang the touch panel externally on the display panel, and it is also the most common form at present; resistive, capacitive and other technologies are available, usually manufactured by another touch panel manufacturer, and then combined with the display panel. For fitting and assembly.
In-Cell Touch technology integrates touch elements into the display panel, so that the display panel itself has touch functions, so there is no need to perform additional processes for bonding or assembling the touch panel. This technology is usually Developed by the panel factory.
However, regardless of In-Cell Touch technology, On-Cell Touch technology, or Out Cell Touch technology, the upper glass substrate or the lower glass substrate of the display panel is provided with a sensing electrode layer made of transparent conductive material (ITO), which not only increases the cost , It also increases the process procedure, which easily leads to a decrease in the process yield and a soaring process cost, and a stronger backlight is required due to the decrease in the aperture ratio. It will increase power consumption, which is not conducive to the low power consumption requirements of mobile devices. Therefore, there is still room for improvement in the structure of the conventional touch display panel.
The main purpose of this creation is to provide an embedded display touch structure, which can greatly save material costs and processing costs; because there is no need to provide a sensing electrode layer made of transparent conductive material (ITO) on the upper glass substrate or the lower glass substrate of the display panel According to this, the cost can be reduced, and the manufacturing process can be reduced.
According to one of the features of this creation, this creation proposes an in-cell display touch structure, which includes an upper substrate, a lower substrate, a thin film transistor and a sensing electrode layer.

The gate driving line sublayer has a plurality of gate driving lines and a plurality of connecting line segments, the plurality of gate driving lines are arranged according to a first direction, and the plurality of connecting line segments are arranged according to a second direction, The plurality of connecting line segments in the second direction are separated by the plurality of gate driving lines. The source driving line sublayer is located on the surface of the gate driving line sublayer opposite to the surface of the display material layer, and has a plurality of source driving lines, a plurality of sensing conductor lines, and a plurality of sensing conductor line segments. The plurality of source driving lines are arranged according to the second direction, the plurality of sensing conductor lines are arranged according to the second direction, and are parallel to the plurality of source driving lines, and the plurality of sensing conductor line segments are arranged according to the first Direction setting, the first A plurality of inductive conductor line segments in one direction are separated by the plurality of source drive lines and the plurality of inductive conductor lines; among them, part of the plurality of inductive conductor line segments are electrically connected with part of the connecting line segments to form a plurality of Inductive conductor block in the first direction.
