Embodiment Construction

[0031] In order to make the purposes, 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 with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments These are some 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 shall fall within the protection scope of the present invention.

[0032] In order to enhance the display effect, the existing LED display usually pursues the characteristics of high contrast ratio. At present, the commonly used method to achieve high contrast is to control all channels to be turned off at the same time in the same display cycle. In the case that the currents of each channel are the same, th...

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 device. Background technique [0002] Contrast refers to the measurement of 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 usually has the characteristics of high contrast ratio. figure 1 Shows the common anode LED display basic circuit, figure 2 show figure 1 The high-contrast timing diagram corresponding to the middle circuit. In a display cycle, the LED lighting start time of the high-brightness display is earlier than that of the low-brightness display, so that the LED display screen driven by the same driver chip presents a high contrast ratio. [0003] In the case of high contrast, current flows through the output channel of t...
