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. |
