Embodiment Construction

[0029] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .

[0030] Please refer to figure 1 with 2 As shown, an integrated pixel-filled LCD splicing screen with zero seams based on HDbaseT signal transmission, which includes a plurality of splicing sub-screens 2, a processor 1, and an HDbaseT input interface 3; wherein, the HDbaseT input interface 3 is processed The device 1 is electrically connected to the plurality of spliced ​​sub-screens 2 . The splicing sub-screens 2 all use liquid crystal displays, and the external images or / and videos are transmitted to the splicing sub-screen 2 through the HDbaseT input interface 3 for display. In a preferred embodiment of the present invention, the transmitted image...

Abstract

The invention discloses an integrated pixel filling zero-joint liquid crystal splicing screen based on HDbaseT signal transmission. The splicing screen comprises a plurality of splicing sub-screens, aprocessor and an HDbaseT input interface, wherein the HDbaseT input interface is electrically connected with the multiple splicing sub-screens through the processor; the processor comprises an imagepreprocessing module, a joint defining module and a joint eliminating module, wherein the image preprocessing module is used for preprocessing an image so as to adapt to the corresponding splicing sub-screens, the joint defining module is used for defining joints between adjacent images, and the joint eliminating module is used for eliminating the defined joints so as to enable the images at the joints to adapt to images in other regions. By defining the joints, the joints extend to splicing sub-screen gaps and peripheries, the images at the joints are made to adapt to the images in other regions in a gray compensation mode, pixel filling integration and liquid crystal splicing screen zero joint are achieved from the display effect, and therefore the display requirement for HDbaseT signaltransmission is met.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an integrated pixel-filled liquid crystal splicing screen based on HDbaseT signal transmission. Background technique [0002] The splicing screen is a splicing display screen, which is made up of multiple display screens and can display large-scale images. DBaseT technology is a global standard for ultra-high-definition digital transmission. It transmits uncompressed ultra-high-definition audio and video through an ordinary network cable without loss of transmission performance and quality; for HDbaseT signal transmission, even a small seam will be reflected It is very obvious that the display effect is very poor. Therefore, how to reduce or eliminate the joints formed after splicing multiple display screens is a technical difficulty in the field of splicing display, especially in the field of HDbaseT signal transmission. Contents of the invention [0003] In order to overco...
