Description
Technical field
The present invention relates to light guide plate mesh point shadow reinforcement field, in particular a kind of disposal route and device based on the reinforcement of light guide plate mesh point shadow.
Background technology
Along with LED LCD TV demand sharply rises violently; The development of LED-backlit module field is swift and violent, considers that from the angle of energy-saving and environmental protection, cost LED light inlet mode changes one-sided light inlet into by four side light inlets gradually gradually; And LED lamp center distance becomes greatly gradually, exists LED lamp center distance not wait situation.So have dark space, shadow phenomenon after TV module backlight is lighted.
The generation of shadow be since the shadow zone to extraradial luminous flux less than the peripheral region, thereby generate a contrast with bright area on every side.When this contrast reach contrast sensitivity function threshold value that human eye can differentiate when above " human eye " judge that this zone is the dark space.The principle essence of site reinforcement is exactly that this contrast that generates is reduced to below the threshold value of human eye resolution.
The disposal route of present module shadow backlight is to adopt the mode of light guide plate mesh point zone reinforcement; And the technological approaches of elliptical region reinforcement is existing reinforcement commonly used, and is as shown in Figure 1, the shadow zone; Particularly lamp bar shadow zone is because the shape that concerns of light mixing distance generally is tending towards triangle 100; As shown in Figure 1, delta-shaped region 100 parts are the signal of shadow district, and the ellipse of dotted portion is elliptical region 110 reinforcement processing modes; 101 is the site, is the reinforcement district in delta-shaped region 100 to the elliptical region.
The general employing of light guide plate mesh point design programmed control design is generally based on reinforcement equation in elliptical region site in the disposal route of light guide plate mesh point shadow reinforcement in the prior art:
Wherein (M N) is Fig. 1 intermediate cam shape 100 intersection point point coordinate, and a, b are the major semi-axis of ellipse 110 and the size of minor semi-axis.Through changing the gradual change trend that e1 controls oval in-house network point radius, reached the purpose of reinforcement.The method of prior art elliptical region reinforcement following problem can occur when revising the site: as shown in Figure 1; Can find out dark-coloured part (being to be the reinforcement district delta-shaped region 100 to elliptical region 110 in) outside triangle 100 by extra carrying out reinforcement, can cause other optics non-uniform phenomenons then.
Therefore, prior art awaits to improve and development.
Summary of the invention
The technical matters that the present invention will solve is, to the above-mentioned defective of prior art, a kind of disposal route and device based on the reinforcement of light guide plate mesh point shadow is provided, and a kind of new regional reinforcement way is provided, and avoids non-shadow district by extra compensation as much as possible.Be mainly used in the LED-backlit module in the light guide plate mesh point design, thereby promote the visual effect of LED liquid crystal module, and efficient is high, security is good.
