Problems solved by technology

However, this solution has certain shortcomings. Specifically, the resolution of the enlarged image display is limited by the number of optical fibers, and the arrangement of optical fibers is required to be strictly aligned with the arrangement of pixels on the LCD screen, otherwise the image will be disordered.
Obviously, it is undoubtedly very difficult to achieve this in the manufacturing process, so it is difficult for this solution to achieve both high image display resolution and low cost

Embodiment 1

[0045] The optical system structure used in this embodiment and the method for realizing LCD seamless splicing are as follows: Figure 2-9 shown. Such as figure 2 As shown, the image display area of ​​the LCD panel is first divided into the middle part 3 and the edge part, and then the edge part is divided into several identical rectangular areas 2, and the purpose of covering the LCD frame 1 is achieved through the design of the optical system. On this basis, the pixels in the middle part of the image display area of ​​the LCD panel are connected with the pixels in the edge part through the receiving screen, so as to completely display the image.

[0046] image 3 Shown is a schematic diagram of the optical system design of this embodiment. The optical system corresponding to the middle part 3 of the LCD panel image display area is a common direct-type LED backlight system 9; the optical system structure corresponding to the edge part of the LCD image display area is as f...

Embodiment 2

[0049] see Figure 10 , this embodiment is the same as the first embodiment except for the following features.

[0050] Such as Figure 10 As shown, the optical system can also omit the design of the offset system, and the purpose of eliminating the frame of the LCD can also be achieved by adjusting the angle of light incident on the LCD panel. Such as Figure 10 As shown, after the light emitted by the light source 4 passes through the uniform light system 5 and the light collimation system 6, the outgoing light forms a certain angle with the normal direction of the LCD panel. By adjusting and receiving the height of the edge portion 8 of the screen as H, the purpose of covering the LCD frame can be achieved. If the width of the LCD frame is L, the angle at which the light needs to be inclined is θ=atan(L / H).

[0051] Such as Figure 10 As shown, an aperture structure 11 is also provided between the light homogenization system and the light collimation system in this embo...

Embodiment 3

[0053] see Figure 11 , this embodiment is the same as the first embodiment except for the following features.

[0054] Such as Figure 11 As shown, the design of the light collimation system 6 and the offset system 7 can also be omitted in this example. Such as Figure 11 As shown, the magnification and offset of the image can be directly carried out by utilizing the property that the light has a certain included angle (the value can be determined according to specific needs) with the normal direction of the LCD panel after passing through the uniform light system 5, so as to reach the final coverage of the frame 1 of the LCD panel. Purpose.

[0055] The LCD seamless splicing system described in the above embodiments is efficient, energy-saving, and compact in structure, and is not only suitable for 1×N-dimensional seamless splicing, but also suitable for N×N (N≥2)-dimensional seamless splicing, and has no loss of pixels. The system structure is easy to realize based on t...

Abstract

The invention relates to the technical field of LCD (liquid crystal display), and particularly discloses an LCD seamless splicing system. The system comprises an LCD panel, an optical system and a receiving screen, wherein multiple rectangular areas are arranged on the edge of an image display area of the LCD panel; the length and width of each rectangular area are greater than the width of the border of the LCD panel; the optical system enables each rectangular area to obtain light spots with uniform illumination and to deviate according to the predetermined direction and position to cover the border of the LCD panel; and the receiving screen enables the pixels in the middle and pixels on the edge of the image display area of the LCD panel to be connected so as to completely display the image. According to the invention, the edge of the image display area of the LCD panel is divided into multiple rectangular areas, and an optical system at the edge is designed accordingly so that the border of the LCD panel is covered by lights; and due to the matched receiving screen structure, the image is completely displayed, and LCD splicing seams can be effectively eliminated.

Description

technical field [0001] The invention relates to the technical field of LCD display, in particular to a system for seamless LCD splicing and display, which can effectively eliminate LCD splicing seams. Background technique [0002] In today's society, the demand for various super-large screen displays is increasing day by day. At present, large-size LCDs can reach 80 inches to 100 inches, but it is still difficult to meet the needs of some occasions (such as subway monitoring rooms, etc.). As a result, LCD splicing display came into being, and gradually emerged in the field of large-screen display. [0003] When splicing LCD panels, due to the requirements of the surrounding driving circuits and production processes, it is inevitable to leave a certain space around the display image on the LCD panel, resulting in a "frame" on the display screen when multiple LCD panels are spliced. This causes the picture to be divided, which destroys the continuity and integrity of the imag...
