Embodiment Construction

[0033] Before introducing this application, let me briefly introduce the devices and working principles related to the thin film transistor TFT.

[0034] The TFT liquid crystal display is mainly composed of three parts: the rear panel module, the liquid crystal layer and the front panel module.

[0035] The rear panel module refers to the part behind the liquid crystal layer, which is mainly composed of a rear polarizing plate, a glass plate, a pixel unit (the pixel unit includes a pixel electrode, thin film transistor and other structures), and a rear alignment film. Each pixel unit includes multiple sub Pixel unit, such as: a pixel unit includes three primary colors of sub-pixel units; three primary colors of sub-pixel units include sub-pixel units with a red emission color, sub-pixel units with a green emission color, and sub-pixel units with a blue emission color. Pixel unit. It should be noted that the sub-pixels involved in this application may also be referred to as sub-pix...

Abstract

The invention provides a display substrate and a display device. The display substrate comprises a plurality of pixel grids, wherein a specific number of sub pixels are set in each pixel grid; each sub pixel is correspondingly provided with a thin film transistor (TFT); and in each pixel grid, at least two TFTs are symmetric along the geometric center of the pixel grid. By change of a TFT arrangement mode design of a glass panel, the TFTs in the pixel grids are not totally arranged at the same positions of the corresponding sub pixels, variations of parasitic capacitors of the TFTs can compensate one other to a certain degree, and the variations of the parasitic capacitors of the TFTs in the whole pixel grids are reduced greatly; and thus, large-area blackening or whitening of the displaysubstrate is avoided macroscopically, and meanwhile, a display result is uniform visually.

Description

Technical field [0001] The present application relates to the field of display technology. Specifically, the present application relates to a display substrate and a display device. Background technique [0002] There are many display devices used for display functions in daily life, such as display screens, display panels, and so on. If some display devices are used in the industrial field, the user can view the internal structure of the electronic accessories through the display device; if they are used in the medical field, the user can view the disease inside the patient's body through the display device. It can be seen that the performance of the display device is directly related to many aspects of people's work and life. [0003] Attached figure 1 It is an arrangement of thin film transistors TFT on the glass panel of a display device in the prior art, with figure 1 The middle number 7 represents TFT (Thin Film Transistor, thin film transistor), the number 8 represents the ...
