Embodiment Construction

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0032] In order to enhance the display effect, the existing LED display screen usually pursues the characteristic of high contrast ratio. At present, the commonly used method to achieve high contrast is to control all channels to turn off at the same time point in the same display cycle. When the current of each channel is the same, the starting time of LED l...

Abstract

The invention relates to the display technology field and discloses an LED display control method and system, and an electronic device. The method comprises steps that the total energy of the LED of each channel in a display period is obtained; loss energy of the LED of each channel is obtained in the same period; the loss energy of the LED of each channel is compared with the total energy of theLED of each channel to obtain a comparison result; according to the comparison result, the display time of the LED of the corresponding channel is adjusted. The method is advantaged in that through comparing the loss energy of the LED of each channel with the pre-obtained total energy of the LED of each channel without loss, according to the comparison result, the display time of the LED of the corresponding channel is adjusted, compensation of brightness loss is facilitated, and display consistency of the LED is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an LED display control method, system and electronic equipment. Background technique [0002] Contrast refers to the measurement of the different brightness levels between the brightest white and the darkest black in the light and dark areas of an image, that is, the size of the grayscale contrast of an image. In order to enhance the display effect, the current LED display screens usually have the characteristics of high contrast. figure 1 shows the basic circuit of common anode LED display, figure 2 show figure 1 The high-contrast timing diagram corresponding to the middle circuit. In one display cycle, the LED lighting start time of high-brightness display is earlier than that of low-brightness display, so that the LED display screen driven by the same driver chip can present high contrast. [0003] In the case of high contrast, current flows through the output channel of...
