Because light-emitting component 18 heat production of this module 12 backlight are more, cause temperature higher, reach as high as about 70 ℃, high temperature makes the printing net-point 134 that is positioned on light guide plate 13 bottom surfaces 132 come off easily or transfer printing sticks to this reflector plate 14 surfaces, thereby causes the optical quality of this liquid crystal indicator 10 not good.Therefore, come off because of high temperature or be transferred on the reflector plate 14 in order to prevent printing net-point 134, industry adopts usually to be had the good singularity optical ink material of stickability and makes this printing net-point 134 via fabrography.Yet, this special optical ink material, as UV (Ultraviolet) transparent ink, its film forming needs under the UV rayed, make it that cross-linking polymerization take place and instantaneous solidification formation, processing procedure complexity and tool costliness make that these module 12 whole manufacturing costs backlight are higher, thereby cause the cost of this liquid crystal indicator 10 also higher.
Summary of the invention
For the easy impaired and cost problem of higher of the lattice point structure that solves module backlight in the prior art, be necessary to provide a kind of optical quality preferable and lower-cost module backlight.
In order to solve in the prior art relatively poor and the higher relatively poor and cost problem of higher of liquid crystal indicator optical quality that causes of cost, also be necessary to provide a kind of liquid crystal indicator with higher optical quality and lower cost module backlight because of module optical quality backlight.
A kind of module backlight, it comprise a light guide plate, be arranged at the light source of light guide plate one side, one and the reflector plate and of the stacked setting of this light guide plate be arranged at transparent membrane between this light guide plate and the reflector plate.This transparent membrane and this light guide plate, this reflector plate split are provided with.The surface of contiguous this light guide plate one side of this transparent membrane is provided with a plurality of printing net-points.
A kind of liquid crystal indicator, it comprises that a liquid crystal panel and provides the module backlight of planar light for this liquid crystal panel.This module backlight comprise a light guide plate, be arranged at the light source of light guide plate one side, one and the reflector plate and of the stacked setting of this light guide plate be arranged at transparent membrane between this light guide plate and the reflector plate.This transparent membrane and this light guide plate, this reflector plate split are provided with.The surface of contiguous this light guide plate one side of this transparent membrane is provided with a plurality of printing net-points.
Because the printing net-point of this liquid crystal indicator is arranged on one independently on the transparent membrane, and do not contact with this reflector plate, therefore in hot environment, obscission or transfer printing paste can Yin Gaowen take place on this reflector plate in the printing net-point of this transparent membrane, thereby guarantee the optical quality of this liquid crystal indicator.And because this printing net-point do not contact with this reflector plate, so this printing net-point can use traditional heat curing-type ink material film forming, thereby reduces the cost of this liquid crystal indicator.
