Abstract
The invention discloses a light guide plate, a liquid crystal display as well as a processing device and a processing method for the light guide plate. The light guide plate comprises a light emitting surface fine structure light guide plate zone and two plane light guide plate zones positioned on the two opposite sides of the light emitting surface fine structure light guide plate zone. Therefore, when the light guide plate is cut, the light guide plate can be cut along the plane light guide plate zones, and the problem that the secondary cutting is needed due to pause guide, so that the unsmooth side surfaces of the light guide plate are formed to affect the light guide effect of the light guide plate is avoided. Besides, fixing structures (for example, grooves and/or projections) of the light guide plate can be arranged on the plane light guide plate zones (practice shows that bright line problems cannot easily occur in the plane light guide plate), so that bright line phenomena occurring due to the arrangement of the fixing structures can be reduced, and accordingly, the visual effect of the liquid crystal display can be enhanced.
Description
Technical field
The present invention relates to liquid crystal indicator technical field, be specifically related to a kind of light guide plate, liquid crystal indicator, the processing unit (plant) of light guide plate and job operation.
Background technology
At present, computer monitor and LCD TV all must rely on backlight module to provide light source, and LGP (Light guide plate, light guide plate) is then the part that backlight module obtains uniform area light source most critical.Current LGP is mainly divided into light output surface microtexture LGP and dull and stereotyped LGP according to surface structure, described light output surface microtexture LGP as shown in Figure 1, light output surface microtexture LGP100 just to the surperficial 100a of display window be male and fomale(M&F) arrange, flat light guide plate then in plane arrange.
Compare flat light guide plate, light output surface microtexture LGP has a lot of advantages in quality, as follows:
1, module optical brightness is made to promote 6 ~ 12%;
2, the directive property of light is stronger, more assembles, module Region control better effects if;
3, LED (Light Emitting Diode, light emitting diode) light source consumption can be reduced and energy-conservation;
4, module shielding is higher, effectively can promote yield.
Just because of all advantages of light output surface microtexture LGP, it is widely used, but light output surface microtexture LGP exists following problem in the application at present:
1, when the large sheet material of light output surface microtexture cuts into the light guide plate size of needs, require very high to cutting and forming machine device, due to light refraction and the reflex of surperficial light output surface microtexture, if occur discontinuous in cutting, the phenomenon (being commonly called as a cutter) of pausing, occur tying trace at a second time cutter Working position and a front Working position end, namely when the degree of depth of twice processing is inconsistent, the side of LGP is made to occur rough phenomenon, thus there will be the phenomenon of bright dark inequality, working depth is larger, the closer to the viewing area of liquid-crystalline glasses, show brighter, this phenomenon is the most outstanding in current ultra-narrow limit machine.As shown in Figure 2, light output surface microtexture LGP100 just to the surperficial 100a of display window, cut side 100b in other words conj.or perhaps fixing time fixing then 100b, incident side 100c, there is the phenomenon that light luminance differs in the fixing then 100b of light output surface microtexture LGP100.
2, in order to safe fixed L GP, in module design, often need in LGP structure to be processed into non-rectangle structure, for common downside light inlet (light source is bottom module), the contour structures of usual LGP is as the LGP two kinds of LGP and Fig. 4 indent of Fig. 3 evagination, at the left and right sides 100b of LGP100, protuberance 1 or groove 2 are set, this protuberance 1 or groove 2 in order to be mounted at LGP100 liquid crystal indicator as in the casing of LCD TV time, coordinate with the fixed sturcture in the casing of described LCD TV and install, but, be not difficult to find in practical application:
A, the edges and corners formed at protuberance 1 or the groove 2 of Fig. 3 and Fig. 4, due to light output surface microtexture LGP
Surface prism structures reason, light there will be " < ", " > " shape bright line through these positions, and the closer to incident side 100C (corresponding incident side 100C is provided with LED 200), this phenomenon is more obvious, prevailing along with ultra-narrow frame TV, the problems referred to above have become design segments very stubborn problem, urgently to be resolved hurrily;
B, another in the LGP100 shown in LGP100 and Fig. 4 of indent, due to groove 2 part, to compare other territories, region distance liquid crystal effective display area nearer, there is scattering process in advance in the surperficial light output surface microtexture LGP part that light divides through inner groovy, cause groove 2 part adjacent area of comparing brighter, cause module to look effect defect.
For this problem, the production dynamics in current module production is as follows:
First: avoid the LGP construction profile of concave or convex to design, adopt other method fixed L GP, such as add location silicagel pad, add incident side reference column etc.Because this locator meams effectively can not limit the activity space of LGP in module, module reliability is far worse than the configuration design of concave or convex formula.
Second: in appearance " < ", " > " shape bright line position, use black oiliness pen core blacking process, black absorption light, alleviates the scattering process of concave or convex position.But the method for this blacking on transparent LGP material, require extremely strict to the operation technique of operating personnel, heavy or light all can causing looks the bad of effect.Separately due to the Characteristics reasons on light output surface microtexture LGP surface, the very low power following current of black pen core easily along light output surface microtexture LGP surface, in liquid crystal module visible area, causes that to look effect bad.
