The invention discloses a micro-display array passive drive line power loss optimization circuit, which belongs to the technical field of light-emitting array passive drive, and is characterized in that it comprises: a display light-emitting array for displaying image information and or text information; , used to generate a drive signal, the drive signal is used to control the light-emitting state of the pixels of the display light-emitting array; a passive connection line, the passive connection line completes the connection between the power drive module and the display light-emitting array; logic control The module is used to generate a timing signal, and the timing signal is used to control the working timing of the power driving module; the logic control module provides the driving logic command for the power driving module, and selects the shortest connection line according to the pixel position in the light emitting array chip. The present invention connects both ends of each interconnection line to output electrodes, selects through a logic control module, and selects the shortest loop path of array pixels, so as to achieve the purpose of reducing the loss of passive driving lines.
Description
technical field [0001] The invention belongs to the technical field of passive driving of light-emitting arrays, and in particular relates to a power loss optimization circuit of a passive driving circuit of a micro-display array. Background technique [0002] Display plays an increasingly important role in human social life, especially in the current information society, people's life is inseparable from display. Displays are required for computer screens, mobile phone screens, and various smart wearable devices. With the continuous progress of material science, display technology has developed by leaps and bounds. At present, liquid crystal display (LCD) and organic light emitting diode (OLED) display are the two main flat panel display technologies. Displays are considered to be the most promising of the next generation display technologies. [0003] Displays are moving toward higher resolutions, smaller pixel sizes and smaller pixel pitches, and more energy-efficient. ...
