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 display cycle of the complete gray scale, 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 digits, it is the number of times the LED is lit per second corresponding to a certain digit of the grayscale data; the effective output times of the a-th digit value refers to the corresponding interval of the a-th digit value within the display cycle. The number...

Abstract

The invention discloses a method for improving the display frequency of fixed chain length, which comprises preset step and steps for intercepting, sending and displaying, wherein the preset step comprises: A1. setting effective digit L; and the steps for intercepting, sending and displaying comprise: B1. reducing the length of a data chain of display data to be L, and displaying the modified display data. The invention reduces the chain length of the display data, thus correspondingly reducing the display time, increasing the effective display times within the equal time, improving the display refreshing frequency and the display quality, avoiding the overhigh loss of brightness, and effectively enhancing the low gray scale display capability on the premise of maintaining the display accuracy not to be changed all the time.

Description

technical field [0001] The invention relates to the control of LED display screens, in particular to a method for increasing the display frequency by fixing the chain length. 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 inventi...
