Three, utility model content:
The technical matters that the utility model solves: lightening hole and colour attaching area inverse are unobvious when working at the display screen made from existing demonstration module, defectives such as contrast is obvious inadequately when showing low-light level, low gray scale color signal, propose a kind of grid-shaped strip line and show module, can effectively improve picture contrast, reduce the influence of ambient light reflection and convergent hole self color spot the LED display curtain.
The technical scheme that the utility model adopted:
A kind of grid-shaped strip line shows module, contain housing, face shield and PCB substrate, it is characterized in that: on the PCB substrate, directly be the luminescence chip that certain matrix array is arranged with the solid brilliant technology welding of chip, described luminescence chip positive and negative electrode lead-in wire is drawn from the PCB substrate back, PCB substrate setting-in is in the housing that is complementary with it, luminescence chip on the corresponding PCB substrate of described housing is provided with corresponding convergent hole, housing outer surface is transparent face mask fixedly, and the space in the housing between PCB substrate and the face shield is a packing colloid.
Described grid-shaped strip line shows module, luminescence chip is red, green, blue three look full-color light-emitting chip portfolios, luminescence chip is the 4*4 arrayed, or is the 8*8 arrayed, and near red, green, blue luminescence chip position matrix dot on the PCB substrate is that isosceles triangle is arranged or vertical array up and down.
Described grid-shaped strip line shows module, and luminescence chip is monochromatic luminescence chip, or is the dual color light emitting chip portfolio.
Described grid-shaped strip line shows module, and described transparent housing surface is for pitted skin or be provided with the grid-shaped strip line, and the convergent hole of offering on the housing is shaped as circle, or is oval or square, and convergent hole inside is light harvesting, reflective surface.
Described grid-shaped strip line shows module, and described surface of shell and face shield coupling are provided with face shield installing and locating hole, and enclosure interior is provided with PCB substrate orientation post.
Described grid-shaped strip line shows module, smears the black ink coating in the commissure district at the surface of shell convergent hole mutually with convergent hole, and described face shield adopts the taupe transparent material.
Useful good effect of the present utility model:
1, the utility model grid-shaped strip line shows module, directly luminescence chip is welded on the PCB substrate, in the PCB substrate setting-in housing, corresponding luminescence chip is provided with convergent hole on housing, housing external fixation face shield, production technology is simple, can effectively reduce LED display production cost and infrastructure cost.
2, the utility model grid-shaped strip line shows that module passes through the surface of shell blacking, make to show module after face shield is pressed into the glue shell its interlayer face in convergent hole the reflective surface, all the other are black, face shield adopts the taupe transparent material in addition, do not influence printing opacity and energy usable reflection extraneous light, can effectively improve the LED display contrast, significantly improve the display screen quality.
