The signal waveform diagram of the above pixel unit is shown in FIG. 2 . Wherein, when the pixel unit structure in the prior art is used for display, firstly, a gate open voltage with a high level (for example, 15V) is applied to the gate line, that is, a certain high level voltage is applied to the gate of the thin film transistor to make the The thin film transistor is turned on, so that the output signal will be transmitted to the liquid crystal capacitor and the storage capacitor. After the scan is completed, apply a low-level voltage (eg -5V) gate-off voltage to the gate line, that is, the voltage on the gate line becomes a low-level voltage. At this time, the thin film transistor is in an off state, and the liquid crystal capacitor and storage capacitor To maintain the workload, when the thin film transistor is switched from the on state to the off state, the voltage across the liquid crystal will produce a jump, which is usually called the pixel electrode jump voltage ΔV and ΔV satisfies the formula: Among them, VGH represents the gate open voltage applied on the gate line to drive the thin film transistor to turn on, VGL represents the gate close voltage applied to the gate line to drive the thin film transistor to close, Cgs represents the gate-source capacitance of the thin film transistor, and Clc Represents the liquid crystal capacitor, Cst represents the storage capacitor.

The relative positions of the pixel units 100 and the TFTs of the pixel units 100 in the even rows are different. However, for the case where the relative positions of the odd-numbered pixel units and the even-numbered pixel units in the TFT-LCD are inconsistent, when the source-drain metal layer in the TFT is shifted, for example, when it is biased to the right, due to the adjacent The relative positions of the TFTs in the odd-numbered pixel units and the even-numbered pixel units are inconsistent, the Cgs1 of the odd-numbered pixels will decrease, and the Cgs2 of the even-numbered pixels will increase, resulting in the difference between the odd-numbered and even-numbered pixels. , which leads to the difference of ΔV between pixels in odd rows and pixels in even rows, which leads to the problem that the flickering picture of TFT-LCD is not easy to adjust.

It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, not to limit the present invention. And in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

The embodiment of the present invention provides an adjustment method of a display module. In the display module, the relative positions of the driving transistors of pixels in odd rows are the same, the relative positions of the driving transistors of pixels in even rows are the same, and the driving transistors of pixels in odd rows are the same. The relative positions of the transistors and the driving transistors of the pixels in the even rows are different; as shown in FIG. 3 , the method includes:
