Abstract: A device for eliminating spliced borders/bezels of a liquid crystal display screen by means of edge display, which comprises an edge display unit is arranged on the spliced border/bezel of the liquid crystal display screen, a dodging layer is arranged on the edge display unit to serve as a display surface of the edge display unit, and the dodging layer and a displayable area of the liquid crystal display screen are synthesized and fused to display an original input video image.

Abstract: A gamma calibration method based on three primary colors is disclosed. The method comprises following steps: performing the gamma calibration onto one of two electro-optic display systems which have three primary colors with different intrinsic wavelengths; correcting the three primary colors of the two electro-optic display system and an output dominant wavelength of a first system of the two electro-optic display systems, resulting in a transition from the output dominant wavelength of the first system to a output dominant wavelength of a second system of the two electro-optic display system, so that the output dominant wavelength of the first system being more and more consistent with the output dominant wavelength of the second system in color space.

Abstract: The present invention relates to construction of a video wall system. The system is formed by splicing single body of display screens together, and the spliced video wall performs “fully seamless” display, namely, “complete pixel coverage” is realized in any display area of the video wall, and the video wall becomes a display system having no “joints/seams on the screen surface” and no “joints/seams between screens”; and the display screen constructed with the video wall system of the present invention is a “spliced seamless screen”: namely, a display screen which is “seamed before splicing” and “fully seamless after splicing”.

Abstract: A method for three-primary-color combined gamma calibration is disclosed. Three-primary-color combined gamma calibration is applied to two electro-optic display systems with three primary colors having intrinsic wavelengths which are not completely the same or to a single electro-optic display system, Not only the electro-optic nonlinearity is calibrated but also the output dominant wavelengths of the systems, are calibrated. This calibration is achieved by way of actively bringing in and superposing other primary color components, and the superposed components are the functions of the calibrated primary colors in the whole color gamut space.

Abstract: A method for pixel to pixel displaying an input video on a spliced display screen is provided. In the spliced display screen, actual physical pixels of a display area of each display screen are distributed on the basis of a physical outer diameter of the display screen according to an nK video standard. The physical outer diameter includes a screen margin/bezel and a display area of a display screen. The physical pixels of the nK video standard are uniformly distributed in the whole physical outer diameter of the display screen with a bezel, including being uniformly distributed in the width of the margin/bezel. The actual physical pixels in the display area of the display screen are fewer than those of the nK video standard, and the width occupied by the missing pixels is consistent with that occupied by the display screen margin/bezel.

Abstract: An apparatus for eliminating splicing frames of a display screen includes a first display device, a second display device, and a processing circuit. The first display device, a first display driver coupled to the first display screen, and a frame at an edge of the first display screen for supporting the first display screen. The second display device includes a second display screen covering the frame, and a second display driver coupled to the second display screen. The processing circuit is configured to receive data of the first image, determine pixels to be displayed in the first display device and pixels to be displayed in the second display device, and provide the pixels to the first display device and the second display device.

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.
