Planar display device

Abstract

The present invention relates to a flat-panel display,including a glass base plate, a light-conducting plate, a lamp tube and a backframe. The light-conducting plate has an incident end, a light-emerging face, a front and a bottom face, its light-emerging face is correspondent to the glass base plate, and the lamp tube is placed in the incident end of said light-conducting plate, the light emitted from lamp tube can be fed into the light-conducting plate from incident end, and then emerged from light-emerging face so as to provide light source required for glass base plate display. The backframe and bottom face of front end of said light-conducting plate are mutually combined together by utilizing a double-back tape, and the backframe and light-emerging face of said light-conducting plate are fixed by using a gasket, the glass base plate is loaded on said gasket.

Description

technical field [0001] The invention relates to a flat display, in particular to a flat display with functions of shock resistance and light leakage avoidance. Background technique [0002] Please refer to FIG. 1 , which is a side sectional view of a flat panel display in the prior art. In the figure, the flat panel display 10 includes a glass substrate 12 , a light guide plate 14 , a light tube 16 , a lampshade 18 , a back frame 20 and a front frame 22 . [0003] The glass substrate 12 is a non-luminescent display element, which needs to be provided with a backlight source by the light guide plate 14 below it to display. There is a liquid crystal layer and a color filter layer inside the glass substrate 12. The glass substrate is The lightness and darkness of the light is determined by the alignment direction of the liquid crystal molecules in the liquid crystal layer, and the color of the light output is determined by the color filter layer. [0004] The light guide plat...

Problems solved by technology

[0014] Although the overall brightness of the conventional technology 2 has better uniformity than the conventional technology 1, due to the insufficient thickness of the gasket 47, the shock-absorbing ability is limited, so it can only provide the ability to prevent the glass substrate 32 from sliding, and is shock-resistant. not good

[0015] In addition, the front end of the light guide plate in the prior art 2 can provide a limited attachment area for the double-sided tape, resulting in insufficient fixing capacity of the double-sided tape 45. When subjected to a large impact force, the fixing ability of the double-sided adhesive tape 45 may fail, causing the light guide plate 34 to hit the lamp tube 36, resulting in damage to the lamp tube 36 or the light guide plate 34 itself

[0016] And because the prior art 2 has no light-shielding design on the front end 343 of the light guide plate, in the process of light guide, there will still be part of the light 33 that will be emitted through this place and cause light leakage (as shown in FIG. 3C ), which will affect the Image Quality of Flat Panel Displays
