Description
Technical field
The utility model relates to a kind of optical filter, and espespecially in the inside casing district of black matrix", have multiple first perforate, have multiple second perforate in housing district, the area of wherein this second perforate is less than the area of the colored filter of this first perforate.
Background technology
Liquid crystal display (LiquidCrystalDisplay, LCD) at large as vision imaging end device of all kinds, as outdoor large advertising billboard, desktop computer displays, laptop computer displays, Mobile phone type display, electronic photo album etc.Because liquid crystal display not only possesses the advantage that power consumption is low and radiation is low, more have concurrently compact, the advantages such as portability is good, thus traditional display is defeated, suddenly become the main trend technology of monitor market, and under the adding fuel to the flames that there is many benefits compared to traditional monitor, liquid crystal display rises to as market mainstream technology, make many technician in industry, lower a large amount of time is pounded drastically one after another in inventor or R&D team, money carries out large quantifier elimination for liquid crystal display increased quality aspect again, LCD Technology is made to become a major industry at TaiWan, China, liquid crystal display is made to become the main export of TaiWan, China and bring many economic interests, nowadays the technology in TaiWan, China liquid crystal display still has the growth of advancing by leaps and bounds, and along with the growth of emerging nation, and the increase of display Related product, people still possess the enthusiasm of height to the research of liquid crystal display correlation technique.
Technically, liquid crystal display belongs to a kind of passive type display device, wherein main element can be divided into three parts substantially, be respectively backlight module, liquid crystal panel and colored filter, light source is provided by backlight module among this, made recurring rule arranged by red (R) in colored filter, blue (B), green (G) three kinds of pixel structures again, to be filtered by its light source, reach the effect making liquid crystal panel display color.And at colored filter, usually a glass substrate is comprised, one pixel layer and a black matrix" (BlackMatrix), this glass substrate is used as carrying, in this pixel layer red (R), blue (B), green (G) three kinds of pixel structures stop that other trichromatic light is by the effect to generate colored display respectively, black matrix" is then do not formed red (R) for covering, blue (B), the light that the region of green (G) three kinds of pixel structures penetrates, prevent light leak simultaneously and stop the effects such as the material of pixel structure mixes mutually, black matrix" external form mostly is the structure comprising multiple framework, and distinguish correspondence in respective zones of different to hold the filter layer forming different colours.
But, liquid crystal display after assembling, its viewing area peripheral region has the difference that subregion brightness and display center part have obvious degree, and its reason has two: one for after liquid crystal display and housing assembles, is produced oblique as light leak by edge; The illusion of another reason then for producing under visual contrast.In prior art, for addressing this problem, usually the colored press strip outer peripheral areas be placed in outside viewing area between backlight module and display panel is utilized to provide the function of color compensating, to solve the problem of the dark-state oblique light leakage at edge, panel display section, it can detect after being measured by optical instrument that on viewing area, the emitting brightness of any point is consistent, seem to solve the problem that oblique light leakage produces, but in fact, the visual effect of light and shade difference is to a certain extent there is in the brightness still having liquid crystal display peripheral edge margin when carefully watching with naked eyes compared to viewing area center brightness, in other words, problem is stopped not yet completely, seem the problem that there is different luminance area still to exist due to the illusion produced under visual contrast.In view of this, for in the technological innovation of liquid crystal display now, how to develop a kind of colored filter to provide a kind of liquid crystal display of novelty, the inconvenience that the user of visual contrast to liquid crystal display causes can be improved, the real important topic being related industry and enterprise-like corporations and can not be ignored.
