Problems solved by technology

However, the existence of voltage dividing resistors will inevitably lead to unnecessary waste of power consumption. If tens of thousands or even more of the above-mentioned pixel units are used in a large-scale LED dot matrix display system, the power consumption of the entire system will be even more wasted. serious

Abstract

The embodiment of the invention discloses a light-emitting diode (LED) display control circuit and a display screen, which are used for reducing power consumption and decreasing heat. According to the embodiment of the invention, the LED display control circuit comprises a constant-current circuit, a row scanning control circuit, and an LED group, wherein the LED group is connected between the row scanning control circuit and the constant-current circuit, and the LED display control circuit further comprises a voltage regulating circuit which is connected with the constant-current circuit; the row scanning control circuit is used for controlling LEDs in the LED group to switch on or off; the constant-current circuit is used for controlling working current of the LEDs in the LED group to be constant; and the voltage regulating circuit is used for regulating voltages at two ends of the constant-current circuit, so as to enable the voltages to meet the preset voltage range.

Description

technical field [0001] The invention relates to the technical field of light emitting diode (LED, Light Emitting Diode) display control, in particular to a light emitting diode display control circuit and an LED display screen. Background technique [0002] LED electronic display is a new type of information display media that developed rapidly in the world in the late 1980s. It is composed of dot matrix modules or pixel units composed of light emitting diodes. Due to its high reliability, long service life, strong environmental adaptability, high performance-price ratio, and low cost of use, it has rapidly grown into a mainstream product of flat panel display in just over ten years, and has been widely used in various industries. Widespread popularization and application. In the current LED dot matrix display in the industry, most LED pixels use LED pixel lights with a three-in-one common anode circuit, that is, one pixel is composed of three LED lights of red, green, and ...
