Problems solved by technology

[0003] However, with the pursuit of the resolution of the display, the denser the pixels, the subsequent increase in the number of thin film transistors per unit display area, and the corresponding PCB routing of the display driver board that drives the display is also denser and more complicated.

Embodiment Construction

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relationship between various components under a certain posture (as shown in the accompanying drawings). The relative positional relationship, the movement situation, etc., if the specific posture changes, the directional indication also changes accordingly. ...

Abstract

The invention discloses a display driving board and a display device. The display driving board comprises a time schedule controller, a first level shifter and a second level shifter, wherein the control signal output end of the time schedule controller outputs control signals to the first level shifter and the second level shifter; the first level converter and the second level converter respectively convert the control signal into a first driving signal and a second driving signal, and respectively output the first driving signal and the second driving signal to a first array substrate row driving circuit and a second array substrate row driving circuit on the left side and the right side of the driving display panel; therefore, the first level translator and the second level translator are arranged, so that array substrate row drive signal transmission lines output by the first level translator and the second level translator are not crossed with each other, PCB wiring of the display drive board is greatly simplified, the number of layers of PCBs drawn by a small number of PCBs is reduced, the cost is reduced; meanwhile, the PCBs can be prevented from being widened, the size of the display device is reduced, and the screen ratio of the display device is increased.

Description

technical field [0001] The present invention relates to the technical field of electronic circuits, and in particular, to a display driving board and a display device. Background technique [0002] TFT (Thin Film Transisto, thin film transistor) display is a mainstream display device on various notebook computers and desktop computers. Each liquid crystal pixel on this type of display is driven by a thin film transistor integrated behind the pixel. [0003] However, with the pursuit of display resolution, the pixel points have become denser, and the number of thin-film transistors per unit display area has continued to increase, and the corresponding PCB traces of the display driver board that drive the display are also more dense and complex. . SUMMARY OF THE INVENTION [0004] The main purpose of the present invention is to provide a display driving board, which aims to simplify the PCB wiring of the driving board. [0005] In order to achieve the above object, the pre...
