Embodiment 1
Main enforcement principle of the present invention is that the viewing area, edge of LCD is extended to the frame portion region be adjacent, the frame remainder of LCD covers by the display of recycling luminescent device, its main implementation method moves on the frame of LCD by optical system by the amplification of the display pixel of LCD, occupy the certain space of its frame, being amplified by the display pixel of luminescent device moves on the frame of LCD, occupy the remaining space of LCD frame, that is image LCD frame shown is amplified pixel by optical system by viewing area, LCD edge and luminescent device and expanded on the frame of LCD, one piece can be obtained thus and there is no frame, all can show the LCD of image, thus realize seamless spliced.
A kind of LCD splicing system eliminating display bezel of the specific embodiment of the invention, comprise the LCD that several are spliced into mosaic screen, also comprise optical system, luminescent device, described optical system is located at LCD surface, the rim area of described LCD is divided into inside region and exterior lateral area, the light vertical incidence of LCD edge viewing area outgoing is to optical system, the inside region extending to rim area is amplified by optical system, the light vertical incidence that luminescent device sends, to optical system, amplifies the exterior lateral area extending to rim area by optical system.
A kind of LCD splicing system eliminating display bezel that this specific embodiment provides, the rim area of LCD is covered by the edge pixel of viewing area, LCD edge and the display of a small amount of luminescent device, thus reach the effect eliminating frame, thus realize seamless spliced.
Wherein, LCD is according to the display effect of reality, viewing area and rim area can be divided into, viewing area can be divided into again viewing area, center and viewing area, edge, viewing area, center refers to the core of LCD, rim area refers to the region of not displayable image in LCD, and viewing area, edge refers to the part between viewing area, center and rim area, and the size of viewing area, center and viewing area, edge divides according to actual needs.
In specific implementation process, luminescent device preferentially selects full-color LED lamp, conveniently installs, and full-color LED lamp can be assembled into full-color LED lamp bar 1 in advance, and its structural representation as shown in Figure 1.
In specific implementation process, in order to ensure the display consistency of LCD display and luminescent device, backlight in LCD preferentially adopts the lamp of type identical with luminescent device, fundamentally solves the display difference of LCD rim area, thus ensures the display consistency of whole LCD.When luminescent device preferentially adopts full-color LED lamp bar, the backlight in LCD also preferentially adopts full-color LED lamp to replace former backlight in LCD, the full-color LED lamp after replacement just to liquid crystal cell, for liquid crystal display provides backlight.
In specific implementation process, on the rim area of LCD, the division of inside region and exterior lateral area sets according to the application demand of reality.Usually, the rim area of LCD is divided into inside region and exterior lateral area, namely the width of inside region and exterior lateral area respectively equals the half of LCD rim area, and the pixel that the pixel of the light that the pixel of the viewing area, edge of LCD rim area side and luminescent device send by optical system is expanded respectively accounts for a semispace of rim area.Preferably, full-color LED lamp bar is adopted at luminescent device, and when the backlight of LCD adopts other luminescent devices, LED brightness is generally high, its brightness is far longer than the brightness of LCD, therefore, utilizes this advantage of LED can increase the width of its elimination frame, namely the width eliminating LCD frame by LED is greater than the width utilizing LCD edge pixel to eliminate LCD frame, i.e. on the rim area of LCD, the width of exterior lateral area is greater than the width of inside region.Such as, on the rim area of LCD, the width of exterior lateral area is 2/3rds of LCD rim area, the width of inside region is 1/3rd of LCD rim area, specifically as shown in Figure 2, 1 is optical system, 2 is the viewing area of LCD, 3 is the rim area of LCD, 4 is full-color LED lamp bar, 3 ' is the frame region of the LCD eliminated by the pixel of the viewing area, edge of LCD, the width in this region is 1/3rd of LCD rim area, 3 ' ' be the frame region of LCD eliminated by full-color LED lamp bar 4, the width in this region is 2/3rds of LCD rim area.
In specific implementation process, optical system preferentially adopts the thin plate be made up of array hole, thin plate is made up of highly reflective material or hole wall is coated with high reflectance rete, its effect expands the pixel of viewing area, LCD edge and the pixel of luminescent device, can show on LCD frame.Preferably, the array hole in optical system is straight-through hole.Hole in optical system shows a pixel, and namely each hole unit is a display pixel, and it pixel is amplified and expands on frame.Relative to viewing area, LCD center, multiple pixel is become a pixel by the array hole in optical system, and LCD lighting area equals the actual lighting area of optical system; And relative to LCD rim area, the corresponding LCD part rim area of array hole of optical system and the viewing area, edge of a part of LCD or corresponding LCD part rim area and luminescent device, light-emitting area below such optical system is less than the actual lighting area of optical system, thus realize the amplification of pixel, expand on rim area.Optical system inwall high reverse--bias, light has reflex in hole, and light source amplifies through reflection.The thin plate of this structure has the feature of high scattering, not extinction, can reduce light loss.In specific implementation process, array hole can be square opening can be also circular port, and such as, shown in Fig. 3, be the structural representation of optical system 1, the hole wherein in optical system 1 is square opening.In actual applications, in order to reduce difference, optical system exiting surface can also be provided with even smooth rete, as diffusion barrier.
In specific implementation process, in LCD, backlight and luminescent device can be controlled by control system simultaneously, also can be controlled separately by control system, and concrete mode can be selected according to practical application request.
In specific implementation process, the setting position of luminescent device can be various, its light that it can be made to send by arranging concrete position be just in time positioned at LCD rim area side and can directly vertical incidence to optical system, the transmission of the light that can be conducted by guiding device, the photoconduction utilizing guiding device to be sent by luminescent device to LCD rim area side and vertical incidence to optical system.The set-up mode of luminescent device is described below in conjunction with several specific embodiment.
