Method and equipment for controlling display

Abstract

The embodiment of the invention provides a method for controlling display. The method comprises the following steps that: a main control device receives m data to be displayed of which the display precision is N; the main control device processes each data to be displayed of which the display precision is N into (2N-n) parts and processes the m data to be displayed of which the display precision is N into m*(2N-n) parts according to a data transmission protocol to obtain a sequence of data of which the corresponding number is k (i, j), wherein i is more than and equal to 1 and less than and equal to m, j is more than and equal to 1 and less than and equal to (2N-n), n is more than and equal to 1 and less than and equal to N, n is data precision of each row during actual display, and m is the number of scanning rows of a display screen; the main control device sends the m*(2N-n) parts of display data to a slave device by taking m as a period, wherein the data of which the number is k (i, j) are sequentially sent to the slave device according to an order from 1 to m in a j period; the main control device controls the display screen by a decoding drive unit; and the slave device controls display according to the m*(2N-n) parts of received display data. According to the scheme provided by the invention, the refresh frequency of the display can be effectively improved by dividing the original data into segments and increasing transmission times on the premise of no influence on the precision of the original data, and the method is simple in implementation and efficient.

Description

technical field [0001] The present invention relates to the field of digital communication, in particular, the present invention relates to a display control method and equipment. Background technique [0002] How to control the brightness of LEDs, technology development from the initial analog dimming method to the current pulse width modulation pulse dimming method, and even now many applications can combine analog dimming and pulse width modulation pulse dimming. Analog dimming means that through the written data, the current flowing through the LED is adjusted to change the brightness of the LED. Pulse width modulation pulse dimming refers to adjusting the time width of LED on or off within a period of time. When the LED is turned on, it is driven by a fixed current, which can be set by an external resistor; when the LED is turned off, no current flows. In this way, the display effect within a certain period of time is that the brightness of the lamp has changed. And ...
