Abstract

A splice display includes at least two liquid crystal displays (LCDs) that are mutually spliced, and the LCDs form a spliced frame at a spliced position of the LCD. The splice display further includes an image splitter and at least one organic electroluminescence display (OLED) panel. A frame of the OLED is transparent, and the OLED covers the spliced frame. The image splitter splits an image signal into a plurality of parts, and transmits the split image signal to the OLED and the LCDs for display.

Claims (16)

1. A splice display, comprising:

at least two liquid crystal displays (LCDs) that are mutually spliced; wherein the LCDs form a spliced frames at a spliced position of the LCDs, and a frame of the OLED is transparent; the OLED covering the spliced frame;

at least one organic electroluminescence display (OLED) attached to the spliced frame by an adhesive

an image splitter that splits an image signal into a plurality of parts and transmits the split image signals to the OLED and the LCDs for display;

a color calibrater that calibrates the image signal of the OLED to enable a color saturation of the LCDs and a color saturation of the OLED to be consistent, wherein the color calibrater comprises a display parameter format conversion module, and a hue and saturation adjusting module; the hue and saturation adjusting module comprises a preset lookup table, the display parameter format conversion module converts a display parameter of RGB format in the image signal into a YCbCr parameter, the hue and saturation adjusting module looks the YCbCr parameter up in the lookup table and rewrites the YCbCr parameter into a new YCbCr parameter, the display parameter format conversion module converts the new YCbCr parameter into a new display parameter of the RGB format and transmits the new display parameter of RGB format to the OLED for display; and

a brightness calibrater that increases brightness of a covered zone of the LCD covered by the frame of the OLED to enable the brightness of all zones of the splice display to be uniform.

2. A splice display, comprising:

at least two liquid crystal displays (LCDs) that are mutually spliced,

an image splitter; and

at least one organic electroluminescence display (OLED);

wherein the LCDs form a spliced frame at a spliced position of the LCD; a frame of the OLED is transparent, the OLED covers the spliced frame, and the image splitter splits an image signal into a plurality of parts, and transmits the split image signals to the OLED and the LCDs for display;

wherein the splice display further comprises a color calibrater that calibrates the image signal of the OLED to enable a color saturation of the LCDs and a color saturation of the OLED to be consistent; and

wherein the color calibrater comprises a display parameter format conversion module, and a hue and saturation adjusting module; the hue and saturation adjusting module comprises a preset lookup table, the display parameter format conversion module converts a display parameter of RGB format in the image signal into a YCbCr parameter, the hue and saturation adjusting module looks the YCbCr parameter up in the lookup table and rewrites the YCbCr parameter into a new YCbCr parameter, and the display parameter format conversion module converts the new YCbCr parameter into a new display parameter of the RGB format and transmits the new display parameter of the RGB format to the OLED for display.

3. The splice display of claim 2 , wherein the splice display panel further comprises a brightness calibrater; the brightness calibrater increases brightness of a covered zone of the LCD covered by the frame of the OLED to enable the brightness of all zones of the splice display to be uniform.

4. The splice display of claim 2 , wherein the OLED is in a strip shape or cross shape.

5. The splice display of claim 2 , wherein the OLED is attached to the frame by an adhesive.
