Description
Technical field
The present invention relates to a kind of display panel technology, particularly a kind of light guide plate and preparation method, light guide plate light guide structure
Making mould.
Background technology
The light that light source is sent enters light guide plate, and the uniform taking-up of light is realized by the site of light guide plate bottom, often at present
The light guide panel material seen is generally PMMA (polymethyl methacrylate, acrylic)/MS (methyl methacrylate (MMA) and benzene
Ethene (SM) be primary raw material synthesized by transparent co-polymer) etc. resin material, light directing site make method be in leaded light
Plate original sheet material base carries out ink printing, or carries out light directing site processing by the radium-shine mode such as get ready.In addition, usual backlight
During module group assembling, light guide plate upper surface can place blooming piece, for covering mura (speckle) or increase brightness, but optical film
Piece has particle coating or does optical texture in itself, can partly be reclaimed, returns by blooming piece from the light of light guide plate outgoing
To light guide plate.This usual some light can reduce light loss, phase by placing reflector plate in light guide plate lower surface to reclaim again
Reflector plate is answered to need carrier to support, carrying reflector plate carrier is generally backboard, and for thickness in more than 1mm, material can be Al
(aluminium), SECC (plated steel sheet) etc., backboard typically can also play a part of undertaking whole backlight module intensity.
At present, with the rise of high-end backlight module concept and the development of light guide plate technique, using glass as guide-lighting
The design concept of plate is also more and more, and glass has its unique value as light guide plate, and it has preferable dimensional stability, thus
Ultra-narrow frame backlight module can be made, glass has larger Young's modulus in addition, and its intensity is the 30 of ordinary resin light guide plate
Times or so, thus can simplify in design or even save backboard, ultra-thin module application is realized, but glass light guide plate also has at present
Its defect, disadvantage are exactly as light guide plate, because glass penetrance curve itself is unsmooth, in blue wave band according to glass
Have stronger light absorbs, if liquid crystal display mode packet size increase, distance light travels increase, light in visible light wave range printing opacity ratio not
Consistent phenomenon further expands, and causes in optical propagation direction, dipped beam lateral deviation indigo plant, the yellow phenomenon of distance light lateral deviation, in addition, typically occurs
Light guide plate is required to set light directing site to carry out the uniform of light, light guide plate is printed according to traditional ink, because of ink sheet
Body has stronger light scattering to blue light, and the phenomenon for causing distance light lateral deviation yellow further aggravates, and prints light directing site according to ink,
Aberration is serious in liquid crystal display die set face.Light directing site is built according to the radium-shine mode got ready, light guide plate surface, which has, to be burst
Phenomenon.
