Abstract

The invention provides a combined display screen and interface yield detection method. The combined display screen includes at least two display panels, each of which has at least one splicing interface for electrical connection with other display panels in the combined display screen, and the splicing interface includes a plurality of connecting pins and a detection loop, the detection loop is composed of a plurality of detection pins and detection wiring; wherein, the plurality of connection pins are used to electrically connect with the corresponding connection pins in the splicing interface of other display panels, the same There is no conductive loop between the multiple connection pins in the splicing interface; the multiple detection pins are in one-to-one correspondence with the multiple connection pins, and each detection pin is arranged next to its corresponding connection pin, And it is electrically insulated from the connection pin; the plurality of detection pins are connected through the detection wiring to form a conductive loop, and the conductive loop is electrically insulated from the connection pin.

Description

technical field [0001] The invention relates to the field of electronic display, in particular to a method for detecting the yield rate of a combined display screen and an interface. Background technique [0002] With the development of display technology, Extremely Narrow Border (ENB) technology has become the preferred solution for outdoor large-area electronic display. ENB technology uses multiple small-size display screens to form a large-area outdoor electronic display screen, which effectively reduces the cost of outdoor electronic display screens. [0003] Side bonding (Side Bonding) technology is a key technology that affects the display quality of ENB. Improving the yield of side bonding can effectively reduce the cost of splicing. In the prior art, the pins in the interface of the splicing panel are usually damaged biologically due to wear or impact, and break, resulting in splicing failure. Defects due to this physical damage are uncontrollable and can only be d...
