Abstract

The invention discloses an LED display backboard detection device, which comprises: a carrying platform, a conductive circuit board and LED binding surfaces, wherein the conductive circuit board comprises a plurality of LED binding surfaces, each LED binding surface is connected with a conductive circuit in the conductive circuit board, and each LED binding surface is connected with LED light-emitting elements on to-be-detected backboard in a one-to-one correspondence manner; and a signal controller used for providing voltage for the conductive circuit board. According to the invention, the conductive circuit board transmits voltage to each LED light-emitting element on the to-be-detected backboard and lightens each LED light-emitting element, and the quality of the corresponding positionof the to-be-detected backboard is judged according to the brightness degree of each LED light-emitting element.

Description

technical field [0001] The present application relates to the technical field of displays, in particular to an LED display backplane detection device and a detection method thereof. Background technique [0002] Micro light emitting diode (Micro light emitting diode, referred to as Micro-LED) usually refers to reducing the size of the LED chip to a size within 200 microns on the basis of the traditional LED chip structure, and the red, green, and blue three-color Micro LED according to a certain Regularly arranged on thin film transistors (Thin Film Transistor, TFT for short) or complementary metal oxide semiconductors (Complementary Metal Oxide Semiconductor, COMS for short), form a micro-device capable of realizing full-color display. This kind of display has independently controlled display pixels, and has the characteristics of independent light-emitting control, high brightness, low power consumption, ultra-high resolution and ultra-high color saturation, and the Micro-...
