Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] In the LED control system, the display frequency, or the display frequency of the complete gray scale, corresponds to the complete gray scale display cycle, which is the frequency corresponding to the display time of the complete gray scale, which is the highest switching response frequency of the entire control system , LED gray scale data digital. Wherein, the complete gray-scale display period is the total length of time required for each digit of the gray-scale data to experience a clear corresponding output process. For the lighting frequency of several effective bits, it is the number of LED lighting times per second corresponding to a certain bit of grayscale data.

[0022] An embodiment of the present invention is a method for dynamically adaptively increasing the display frequency, which includes the following steps: shifting...

Abstract

The invention discloses a method for dynamically and adaptively improving display frequency, including the following steps: C-bit left shift is carried out on data to be displayed highest order of which is not one, so that the highest order of display data after being modified is one, and the time of output enable signal thereof is set to be 2-C of the complete time of output enable signal corresponding to the original display data. The output enable signal is utilized, incomplete time effect of OE enable signal causes an effective output signal to be interrupted, and 2N display output times are added, thus improving refreshing frequency, enhancing display quality and avoiding overhigh brightness loss.

Description

technical field [0001] The invention relates to the control of LED display screens, in particular to a method for dynamically self-adapting and increasing display frequency. Background technique [0002] In the LED display, the display quality of the LED display is directly proportional to the display frequency of the LED display, that is, the refresh rate. The higher the display frequency, the smaller the image flickering on the screen and the higher the stability. Also taller. [0003] However, in the prior art, various methods for increasing the display frequency are based on the condition of sacrificing the brightness, for example, by changing the clock frequency of the control device to increase the display frequency, which not only consumes more power, but also increases the display brightness. lower. [0004] Therefore, there are defects in the prior art and need to be improved. Contents of the invention [0005] The technical problem to be solved by the inventio...
