Problems solved by technology

[0003] For large-size display panels, the array substrate in the display panel has a large resistance voltage drop, which causes serious loss in the signal transmission process. In this way, when the signal is transmitted to the area of ​​the array substrate far away from the signal terminal, it cannot meet the requirement that the array substrate be far away from the signal terminal. The charging requirements of the area of ​​the signal terminal lead to a serious insufficient charging rate of the thin film transistors contained in the area of ​​the array substrate far away from the signal terminal, thereby reducing the display effect of the display panel

Embodiment Construction

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0037] For large-size display panels in the prior art, the charging rate of the thin film transistors in the area of ​​the display panel far away from the signal terminals is insufficient, such as figure 1 As shown, the embodiment of the present invention provides a signal control device and method, so as to realize the modulation of the timing of the display control signal.

[0038] Such as figure 1 and figure 2 As shown, when the display control device is appl...

Abstract

The invention discloses a signal control device, a control method, a display control device, and a display device, which relate to the field of display technology and are used to improve the charge rate of thin film transistors contained in an area of ​​an array substrate away from signal terminals, thereby ensuring the display effect of a display panel. The signal control device includes: a signal generating unit for generating an initial enable control signal; a pulse modulation unit connected to the signal generating unit for modulating the pulse displacement of the initial enable control signal to obtain a modulated enable control signal, In each scan period, the pulse displacement of the modulation enabling control signal gradually increases; the modulation enabling control signal is used to control the output timing of the display control signal. The display control device includes the signal control device mentioned in the above technical solution. The signal control device and control method, the display control device and the display device provided by the present invention are used in the display device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a signal control device and a control method, a display control device, and a display device. Background technique [0002] When an existing display panel realizes image display, a timing controller is used to send timing signals to control the transmission time of scanning signals and data signals to the display panel, thereby realizing image display on the display panel. [0003] For large-size display panels, the array substrate in the display panel has a large resistance voltage drop, which causes serious loss in the signal transmission process. In this way, when the signal is transmitted to the area of ​​the array substrate far away from the signal terminal, it cannot meet the requirement that the array substrate be far away from the signal terminal. The charging requirements of the area of ​​the signal terminals lead to a serious insufficient charging rate of the t...
