Description

Touch panel and display integrated driving chip and display device of liquid crystal panel

The author is related to a touch and display integrated driver chip, in particular, a touch panel display integrated driving chip of a liquid crystal panel.

In today's market of various consumer electronic products, portable electronic products such as personal digital assistants (PDAs) and notebooks, and even personal computers and digital home appliances systems have gradually used touch panels ( Touch panel) is a data communication interface tool between the user and the electronic device. When using the touch panel, the user can directly operate and release commands through the objects displayed on the screen, thereby providing a more user-friendly operation interface. In addition, the design of electronic products is light, thin, short and small, so the display device with touch panel has gradually become a key component of various electronic products.

According to the structure, the conventional touch display device can be divided into an external touch display device and an in-cell touch display device. In addition to a display panel, the external touch display device needs to be additionally provided with a separate touch panel on the display surface of the display panel. Therefore, the user can observe the image displayed by the display panel by using the touch panel. To sense its touch position. The in-cell touch display device integrates the touch function into the display panel, so that the same panel has both input and output functions, which can reduce the overall thickness of the touch display device, and is one of the mainstream of the current touch display panel.

However, the conventional touch display panel, because each of the first display patterns of the upper panel needs to be coupled to a common line, is often caused by the first display pattern being located at different positions on the upper panel. scanning The configuration of the line on the upper panel is very complicated, so that the scan line cannot be allocated a sufficient amount, which will cause the upper panel to fail to provide too many touch positions, resulting in a problem that the touch resolution is not high.

[Example of touch panel display and integrated drive wafer of liquid crystal panel]

Please refer to FIG. 3. FIG. 3 is a schematic structural diagram of a touch control and display integrated driving chip of a liquid crystal panel according to an embodiment of the present invention. As shown in FIG. 3, the touch and display integrated driving chip 14 of the liquid crystal panel of the present embodiment is a configuration for changing the scanning pins of the conventional touch display panel. In this embodiment, the second surface 111 includes a first region 1110 and a second region 1111, that is, the second surface 111 of the first substrate 11 is divided into a first region 1110 and a second region 1111. There is no restriction on how the area is divided. In this embodiment, the touch and display integrated driving chip 14 has a plurality of first scanning pins Y1 Y Y4 for sensing the touch signal of the second surface 111 of the liquid crystal panel and a plurality of second scanning pins Y5~ The Y8 is used to sense the touch signal of the second surface 111 on the liquid crystal panel, and the two sets of pins are respectively located on both sides of the data pins S1 to S7. In order to facilitate the description and understanding of the disclosure, only four scanning pins are used as an example in the embodiment, but it is not intended to limit the spirit of the disclosure.

The scan timings of the first scan pins Y1~Y4 and the second scan pins Y5~Y8 are the same. Further, as shown in FIG. 3, the scanning timings of Y1 and Y5 are the same, the scanning timings of Y2 and Y6 are the same, the scanning timings of Y3 and Y7 are the same, and the scanning timings of Y4 and Y8 are the same. In other words, in the embodiment, when the scan pin needs to be coupled to the second surface 111, the first scan pin Y1 can be selectively used depending on where the first display pattern is located at the second surface. Y4 or the second scanning pin Y5~Y8, that is, the first scanning pin Y1 or the second scanning pin Y5, the first scanning pin Y2 or the first scanning pin Y5 or the second scanning pin Y2 Two sweep The pin Y6, the first scan pin Y3 or the second scan pin Y7, the first scan pin Y4 or the second scan pin Y8 are drawn to reduce the wiring complexity.

The first scan pin Y1~Y4 is coupled to the scan line 141 on the first region 1110 that is closer to the first scan pin Y1~Y4, and the second scan pin Y5~Y8 is coupled to the second scan. The scan line 141 on the second region 1111 near the pin Y5~Y8.
