Micro-display array passive drive circuit power loss optimization circuit

Abstract

The invention discloses a micro-display array passive driving line power loss optimization circuit, which belongs to the technical field of light-emitting array passive driving, and is characterized by comprising a display light-emitting array used for displaying image information and / or text information; the power supply driving module is used for generating a driving signal, and the driving signal is used for controlling the light-emitting state of the pixel points of the display light-emitting array; the passive connecting circuit is used for completing the connection between the power supply driving module and the display light-emitting array; the logic control module is used for generating a time sequence signal, and the time sequence signal is used for controlling the working time sequence of the power supply driving module; and the logic control module provides a driving logic command for the power supply driving module, and selects the shortest connecting line according to the pixel position in the light-emitting array chip. The two ends of each interconnection line are connected with the output electrodes, selection is carried out through the logic control module, the loop path with the shortest array pixels is selected, and therefore the purpose of reducing the loss of the passive driving line is achieved.

Description

technical field [0001] The invention belongs to the technical field of light-emitting array passive drive, and in particular relates to a micro-display array passive drive circuit power loss optimization circuit. Background technique [0002] Display plays an increasingly important role in human social life, especially in the current information society, people's lives cannot be separated from display. Computer screens, mobile phone screens, and various smart wearable devices all need display screens. With the continuous advancement of material science, display technology has developed by leaps and bounds. Currently, liquid crystal display (LCD) and organic light-emitting diode (OLED) displays are the two main flat-panel display technologies. In the future, inorganic Micro-LED light-emitting diode-based Displays are considered to be one of the most promising next-generation display technologies. [0003] Displays are developing towards higher resolution, smaller pixel size...
