Embodiment Construction

[0020] In the present invention, when designing the LCD pixel unit, the first touch-sensitive area and the second touch-sensitive area are added, and the gate line and the data line are shared with the pixel electrode area in the original pixel unit, and the gate line and the data line The overlapping part of the touch capacitor is used as the touch capacitor, and the increased first touch sensing area and the second touch sensing area form a touch plane, so as to realize the design of LCD, increase the touch function, reduce the thickness of the LCD, and improve the additional functions of the LCD.

[0021] Such as figure 1 As shown, it is a schematic structural diagram of a pixel unit provided by Embodiment 1 of the present invention. The pixel unit includes: a data line 1, a gate line 2, a pixel electrode area 3, a first touch sensing area 4, and a second touch sensing area 5 .

[0022] Specifically, such as figure 1 As shown, the first touch-sensitive area 4 and the seco...

Abstract

Embodiments of the invention provide a pixel unit and a TFT-LCD with touch function. The pixel unit comprises a data line, a gate line and a pixel electrode formed on a base substrate. The pixel unit further comprises: a first touch layer connected to the data line and not connected to the pixel electrode; and a second touch layer connected to the gate line and not connected to the pixel electrode.

Description

technical field [0001] The invention relates to the technical field of liquid crystal displays, in particular to a pixel unit and a thin film transistor liquid crystal display. Background technique [0002] Thin Film Transistor-Liquid Crystal Display (hereinafter referred to as TFT-LCD), has the advantages of light weight, thin thickness, convenient operation and low power consumption, and is widely used in electronic products such as TVs, mobile phones, monitors, and The application of TFT-LCD with touch function is also more and more extensive. [0003] The TFT-LCD with touch function in the prior art, after the LCD panel and the touch panel (Touch Panel) are designed separately, then the Touch The Panel is combined with the LCD panel to finally form a TFT-LCD with touch function. [0004] The LCD panel displays images mainly by scanning the pixel electrode area in the pixel unit. In the existing pixel unit, the data line is connected to the source of the thin film trans...
