Description

LCD MODULE

The application be Application No. 2012102961432, the applying date be on 08 20th, 2012, invention and created name be The divisional application of the patent of " LCD MODULE and LCD MODULE manufacture method ".

Technical field

The present invention relates to LCD MODULE and its manufacture method, more particularly to small-sized liquid crystal display module and liquid crystal Show module manufacturing methods.

Background technology

General common backlight module, is typically made up of light source, light guide plate, blooming piece and liquid crystal glass layer, by It is many in single part, therefore the manpower in assembling often needs to account for the more than half of whole piece producing line, though there are some to assemble automatically in recent years The importing of board, part manpower is reduced, but still often occurred due to light-strip, light guide plate or framework slightly inclined in assembling Move, cause light source, such as LED light bar in the contraposition upper deviation, and optics briliancy and the affected situation of taste are occurred.

The content of the invention

In view of this, it is necessary to which a kind of LCD MODULE and LCD MODULE system that can overcome above mentioned problem is provided Make method.

A kind of LCD MODULE, it includes a light source and a Liquid Crystal Module.The Liquid Crystal Module includes glass base on one Plate, a lower glass substrate and one is located in liquid crystal layer between the top glass substrate and lower glass substrate, the lower glass substrate face To the light source, and there is a hollow region inside the lower glass substrate, the hollow region has more towards the inner surface of the light source Individual micro-structural is used to scatter the light that the light source is sent.

A kind of LCD MODULE manufacture method, it includes:One light source is provided；One top glass substrate and one to be processed is provided Lower glass substrate；With carbon dioxide laser a hollow region is cut out from laterally inner side outside the lower glass substrate to be processed；Use yttrium YAG processes multiple micro-structurals in an inner surface of the hollow region, so as to form a lower glass substrate；Encapsulation One liquid crystal layer is between the top glass substrate and the lower glass substrate；And the light source is set close to the lower glass substrate, and make Towards the light source, the light that the light source is sent is directly entered the lower glass substrate and through in this inner surface of the lower glass substrate Multiple microstructures scatters of the inner surface of dummy section and enter the liquid crystal layer.

Relative to prior art, LCD MODULE provided by the invention is made micro- inside the lower glass substrate of Liquid Crystal Module Structure so avoids using other light guide plate or diffuser plate, makes whole LCD MODULE to scatter the light that light source is sent Thickness is greatly reduced.

Embodiment

Referring to Fig. 1, LCD MODULE 100 provided in an embodiment of the present invention is a kind of direct-down type LCD display module 100, it includes a light source 10, a Liquid Crystal Module 20 and the transparent substrates 30 being placed in before Liquid Crystal Module 20.

In the present embodiment, the light source 10 contains multiple LED12.In other embodiments, the light source 10 can be other light Source fluorescent tube.The transparent substrates 30 can pass through visible ray, and it can be pliability transparent substrates.

The Liquid Crystal Module 20 includes a top glass substrate 22, and a lower glass substrate 24 and one is located in the top glass substrate 22 And the liquid crystal layer 26 between lower glass substrate 24.The lower glass substrate 24 faces the light source 10, and inside the lower glass substrate 24 With a hollow region 242.The liquid crystal layer 26 contains liquid crystal, drive circuit, electrode and spacer element etc..

The hollow region 242 is not exposed to the lower glass exposed to the relative front side of the lower glass substrate 24 and rear side The other both sides of substrate 24, the i.e. lower glass substrate 24 are still integral type structure.The hollow region 242 height H is about 100 micro- Rice.The light that the hollow region 242 is sent towards the inner surface 246 of the light source with multiple micro-structurals 244 for scattering the light source Line.In the present embodiment, the plurality of micro-structural 244 is continuous V-structure, and in other embodiments, the plurality of micro-structural also may be used Indent round dot for interval or be interval evagination round dot.

Fig. 2 to 4 is referred to, the manufacture method of above-mentioned LCD MODULE 100 may include steps of.

First, there is provided light source 10；Secondly, there is provided a top glass substrate 22 and a lower glass substrate 28 to be processed.

With carbon dioxide (CO2) laser a hollow region is cut out from the 28 outer laterally inner side of lower glass substrate to be processed 242.The hollow region 242 height H is about 100 microns.The hollow region 242 is relative exposed to the lower glass substrate 28 to be processed Front side and rear side, and be not exposed to the other both sides of the lower glass substrate 28 to be processed, i.e. the lower glass substrate 28 to be processed Still it is integral type structure.The carbon dioxide laser wavelength is 10.6 microns.

Multiple micro-structurals 244 are processed with an inner surface 246 of yttrium-aluminium-garnet (YAG) laser in the hollow region 242, So as to form the lower glass substrate 24 of Liquid Crystal Module 20.The yag laser wavelength is 1064 nanometers.The yttrium-aluminium-garnet Laser can process the inner surface 246 from the front side of hollow region 242 and rear side in a manner of slanting.

A liquid crystal layer 26 is encapsulated between the top glass substrate 22 and the lower glass substrate 24.

The light source 10 is set close to the lower glass substrate 24, and makes the inner surface 246 towards this of the lower glass substrate 24 Light source 10.

The light source 10 can be attached at the lower glass substrate 24.The light that the light source 10 is sent is directly entered the lower glass base Multiple micro-structurals 244 of plate 24 and the inner surface 246 through the hollow region 242 scatter and enter the liquid crystal layer 26.

Because the micro-structural of the lower glass substrate 24 of the LCD MODULE 100 can scatter the light that light source 10 sends, The uniform light for sending light source 10 is emitted the Liquid Crystal Module 20, so avoids using other light guide plate or diffuser plate, entirely The thickness of LCD MODULE 100 is greatly reduced.

The LCD MODULE 100 is especially suitable for small size display screen.

It is understood that those skilled in the art can also do other changes in spirit of the invention, this should be all included in Invent it is claimed within the scope of.
