Abstract

The invention discloses a seamless LCD joint method, which comprises the following steps that: an area larger or equal to an LCD frame in length and width is selected in an image display area of an LCD display unit to serve as an image transmission area; two images which are an image required to be displayed in the area and an image required to be displayed at the position of the frame respectively are displayed in the image transmission area by using a row / column division or time / frame division display method; the image required to be displayed at the position of the frame is separated and transmitted by an image transmission device to the position of the frame and to cover the frame part to form a frameless display unit, so that an image on an LCD display unit can be well jointed with an image on an adjacent LCD display unit to realize seamless display to realize the continuity and integrity of a seamless of a whole image on a large-screen LCD joint display screen. The device is simple and easily implementable in technical means and convenient in market promotion and application.

Description

technical field

[0001] The invention relates to large-screen display technology, in particular to an LCD seamless splicing method and a special image transmission device. Background technique

[0002] The existing large-screen LCD display screen is formed by splicing several LCD display units. Due to the requirements of the drive circuit and production process around the panel of the LCD display unit, a frame with a certain space needs to be reserved around the image display area of ​​each LCD display unit (the frame is a non-image display area), and the image cannot be displayed on the frame. Generally, the width of the non-image display area of ​​the frame exceeds 10 mm, and becomes wider as the size of the panel increases. Therefore, when splicing the display screen, it is easy to form a larger splicing seam between adjacent LCD display units, and the splicing seam is the sum of the frame widths of two adjacent LCD display units (generally, the width exceeds 20mm. ), ca...
