The display panel comprises a plurality of scanning lines, a plurality of data lines and a pixel array, wherein the pixel array is formed by arranging a plurality of pixel units, each pixel unit mainly comprises a thin film transistor, a storage capacitor and a liquid crystal unit, each thin film transistor comprises a grid electrode, a source electrode and a drain electrode, the grid electrode of each thin film transistor is connected with a grid electrode driving circuit through the corresponding scanning line, and the source electrode is connected with a source electrode driving circuit through the corresponding data line. The gate driving circuit turns on or off the plurality of thin film transistors connected to the scan lines by supplying gate line scan signals to the plurality of scan lines. When the thin film transistors are turned on, the source driving circuit provides gray scale display voltage for the data lines by providing data signals for the data lines, so that an image signal is stored in each pixel unit. Since the lcd displays images by accumulating charges in the storage capacitor between two opposite electrodes (e.g., the common electrode and the pixel electrode), when the display panel of the lcd is powered off, the accumulated charges will cause the corresponding pixels to be at different gray levels, and thus some images will remain on the display screen.

As shown in fig. 1, the display module includes a display panel 100, a Circuit Board 200, and a Printed Circuit Board (PCB) Board 300, wherein the display panel 100 is connected to the PCB Board 300 through the Circuit Board 200. The display panel 100 is provided with a pixel array 110, a gate driving circuit 120 and a source driving circuit 130. The pixel array 110 is formed by arranging a plurality of scanning lines, a plurality of data lines, and a plurality of pixel units at crossing positions, each pixel unit includes a thin film transistor and a pixel electrode, a gate of the thin film transistor is connected to the gate driving circuit 120 through the scanning lines, a source of the thin film transistor is connected to the source driving circuit 130 through the data lines, and a drain of the thin film transistor is connected to the pixel electrode. The gate driving circuit 120 is configured to sequentially scan a plurality of scan lines to turn on the tfts in a corresponding row, and the source driving circuit 130 is configured to apply a gray scale voltage corresponding to display data to the pixel electrodes when the tfts are turned on.
In order to solve the above technical problem, in the prior art, a plurality of discharge transistors are disposed on a pixel array of a display module (a liquid crystal display), and the plurality of discharge transistors are connected to corresponding data lines. Taking the discharge transistors T1 and T2 in fig. 1 as an example, the discharge transistors T1 and T2 are respectively connected to the corresponding data lines S1 and S2, and the discharge transistors are turned on after the power of the display module is turned off, so as to provide charge discharging paths of the data lines S1 and S2 to ground, thereby enabling the pixel cells to be discharged quickly.
The display module further includes a power management circuit 310 and a level shifter circuit 320 on the PCB 300. One functional pin (XON pin) of the level shifter 320 is connected to the power management circuit 310, and an output pin of the level shifter 320 is connected to control terminals of a plurality of discharge transistors (e.g., discharge transistors T1 and T2). When the power supply of the display panel is normal, the level conversion circuit 320 provides a low level signal to the plurality of discharge transistors, and turns off the plurality of discharge transistors; when the power of the display panel is turned off, the level shifter 320 pulls the control terminals of the discharge transistors to high voltage, and turns on the discharge transistors in the display panel 100, so as to forcibly and rapidly release the charges in the pixel units, thereby eliminating the residual image. In the conventional display module, only one output pin of the Level shifter 320 is used, which causes resource waste of a Level shifter (Level Shift) and increases circuit cost.
