Abstract

This invention relates to a display device for achieving seamless splicing of display screens. The invention comprises several screens spliced in array, wherein a display belt frame is provided on the frame of each screen; the screen and said display belt frame form an integral display plane; a processing circuit that splits the original display plane into the screens and the display belt frames links each of the screens and the display belt frames, said display belt frame being composed of LEDs or OLEDs, and said processing circuit being composed of a video processing card that splits the video images, an LCD/PDP drive circuit and an LED/OLED drive circuit. The advantage of this invention is that it can sufficiently utilize the advantages of both LCD/PDP and LED/OLED and thus eliminate the frames formed during the splicing of several smaller display screens into one larger display screen.

Claims

1. A device for eliminating splicing frames of a display screen, comprising several screens spliced in array, wherein a display belt frame is provided on the frame of each screen;

the screen and said display belt frame form an integral display plane;

a processing circuit that splits the original display plane into the screens and the display belt frames links each of the screens and the display belt frames.

2. A device for eliminating splicing frames of a display screen of claim 1, wherein said display belt frame is composed of LEDs or OLEDs.

3. A device for eliminating splicing frames of a display screen of claim 1, wherein said processing circuit is composed of a video processing card that splits the video images, an LCD/PDP drive circuit and an LED/OLED drive circuit.
