Abstract

The invention provides a combined display screen and an interface yield detection method. The combined display screen comprises at least two display panels, each display panel is provided with at least one splicing interface used for being electrically connected with other display panels in the combined display screen, each splicing interface comprises a plurality of connecting pins and a detection loop, and each detection loop is composed of a plurality of detection pins and detection wires. Wherein the plurality of connecting pins are used for being electrically connected with correspondingconnecting pins in splicing interfaces of other display panels, and a conductive loop does not exist among the plurality of connecting pins in the same splicing interface; Wherein the plurality of detection pins are in one-to-one correspondence with the plurality of connection pins, and each detection pin is arranged beside the corresponding connection pin and is electrically insulated from the connection pin; And the plurality of detection pins are connected through the detection wires to form a conductive loop, and the conductive loop is electrically insulated from the connection pins.

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...
