Abstract

The invention discloses a frameless display strip and a screen splicing system. The frameless display strip is a flexible OLED panel which comprises an effective displaying middle region and two ineffective displaying edge regions in the width direction. The edge regions are bent and adhered to the back face of the middle region. The bending radius is smaller than 1.3mm. The length of the frameless display strip is larger than 8 and the width of the frameless display strip is larger than 8. The frameless display strip is installed in a position of a display screen frame and covers the frame-containing edge parts of the display screen. The frameless display strip and the display screen are spliced to form a synthesis screen to synthesize displayed and input video images. The frameless display strip and the screen splicing system are advantageous in that a visual seamless effect can be achieved on the screen splicing system in a certain visual distance.

Description

technical field [0001] The invention relates to the field of display technology, in particular to the field of borderless display bars and screen splicing systems. Background technique [0002] Organic light-emitting diodes (OLEDs) can be made into ultra-thin and flexible displays. The thickness of OLED panels can be as low as 0.1mm. The best flexibility reported publicly is the flexible OLED panel developed by Nokia and Advanced Film Device. This OLED panel It can be folded 180 degrees in half like paper, the minimum curvature radius (bending radius) is 2mm, and the number of bending times exceeds 100,000. The bending radius should not be too small, because it may cause the resistance of the display electrode to increase, open circuit, and cracks may appear on the surface of the substrate. For products such as mobile phones and TVs, destructive bending is not allowed. . Therefore, the frame is hidden by bending the OLED panel by 180 degrees. The bending radius cannot be t...
