Abstract

The embodiment of the invention provides a spliced LCD screen. The spliced LCD screen at least comprises a first LCD screen, a second LCD screen and a third LCD screen, and the third LCD screen is located between the first LCD screen and the second LCD screen; a first concave part is arranged on one side, close to the third LCD screen, of the first LCD screen, and the first concave part is located in a black matrix area of the first LCD screen; a second concave part is arranged on one side, close to the third LCD screen, of the second LCD screen, and the second concave part is positioned in a black matrix area of the second LCD screen; and one end of the third LCD screen is arranged in the first concave part, and the other end of the third LCD screen is arranged in the second concave part. According to the embodiment of the invention, grooves are formed in the black matrix areas of the display screens on the two sides, then a scanning integrated circuit is arranged in the pixel area, and the third LCD screen treated by the thinning process is arranged in the grooves, so that the problem of splicing seams caused by splicing in a narrow frame module splicing mode can be solved.

Description

technical field [0001] The present application relates to the technical field of display screens, in particular to a spliced ​​LCD display screen. Background technique [0002] In recent years, with the increasing demand for various ultra-large display screens, large-screen display technology has developed rapidly. The mainstream large-screen display technology is the unit box type LED direct display and the splicing of multiple LCD modules. LED has the characteristics of high luminous efficiency, high brightness and low power consumption. Now LED direct display mainly adopts PCB multilayer board, coupled with the way of chip direct drive. The number of LEDs and driver chips used in large pixel pitch direct display is small, and the cost is low. still have an advantage. However, when the pixel pitch is less than 0.8 mm, the number of LEDs and driver chips required to be used increases, and the manufacturing difficulty is also greatly increased, and the cost rises to the poi...
