Embodiment Construction

[0041] In order to further illustrate the display module, its driving method, and display device provided by the embodiments of the present invention, a detailed description will be given below in conjunction with the accompanying drawings.

[0042] In the related art, taking a liquid crystal display device as an example, the liquid crystal display device includes a display area and a peripheral area surrounding the display area. The first data signal line can extend to the peripheral area, and the peripheral area is provided with a MUX and a source driver chip. The provided data signal is transmitted to the data signal line, and the data signal line continues to transmit the received data signal to the corresponding sub-pixel unit, thereby controlling the liquid crystal display device to realize display.

[0043] The inventor of the present invention has found through research that MUX is mainly composed of transistors at present, so the driving performance of transistors det...

Abstract

The invention discloses a display module, a driving method thereof and a display device, which relate to the technical field of display, and aim to solve the problem that when a data signal line of adisplay product is used for providing a data signal, the target display brightness of the display product cannot be achieved due to relatively high MUX loss. Each signal input sub-circuit in the display module comprises at least two transistors, the control signal lines corresponding to the same signal input sub-circuit are used for loading the same control signal, the control signal lines corresponding to different signal input sub-circuits are used for loading different control signals, and the time periods where the effective levels of the different control signals are located are mutuallystaggered; the sum of the channel width-to-length ratios corresponding to the transistors in the at least two transistors is equal to a first preset value, and in the direction perpendicular to the substrate of the display module, the directly facing area between the grid electrode and the active layer of each transistor in the at least two transistors is smaller than a second preset value. The display module provided by the invention is used for displaying pictures.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display module, a driving method thereof, and a display device. Background technique [0002] With the continuous development of display technology, the resolution requirements of display products are getting higher and higher, and the higher the resolution of display products, the more data signal lines are required, because the data signal lines and the source drive in display products Chip connection, the source driver chip provides data signals for the data signal lines, and the number of pins that the source driver chip can connect to the data signal lines is limited, so multiple channels will be introduced between the source driver chip and the data signal lines The selector (English: multiplexer, hereinafter referred to as: MUX), by connecting the multiplexer between a data signal output pin of the source driver chip and multiple data signal lines, realizes a data signa...
