Abstract

The invention provides a micro-structural framework, which is applicable in a backlight module of a liquid crystal display device with a crystal covering film. The micro-structural framework is provided with a plurality of microstructures, and the microstructures are positioned on the surface of the framework opposite to the crystal covering film. When the framework is contacted with the crystal covering film, particles positioned between the framework and the crystal covering film fall into the microstructures. Therefore, the particles between the framework and the crystal covering film cannot generate friction for the crystal covering film, and the crystal covering film is prevented from being further scratched.

Description

A kind of micro-structural framework

Technical field

The invention relates to a kind of framework, and particularly relevant for a kind of micro-structural framework that is used for having the module backlight of the display panels that covers brilliant film.

Background technology

Recently photoelectric technology is constantly weeded out the old and bring forth the new, and adds the arrival of digital times, has promoted the flourish of LCD market.LCD because have that high image quality, volume are little, in light weight, numerous advantages such as low driving voltage and low consumpting power.Therefore be widely used in PDA(Personal Digital Assistant), mobile phone, shoot with video-corder projector, on consumer communication such as mobile computer, desktop display, automobile-used display and projection TV or the electronic product, and replace cathode-ray tube (CRT) gradually, and become the main flow of display.

In present LCD backlight module, in order in narrow space, to realize high-density mounting, used soft additional circuit boards to make the packaged chip carrier engages chip with the flexible base plate circuit technology, be COF (Chip On Film), hereinafter to be referred as covering brilliant film, it directly influences the display effect of LCD.

In order to pursue compact target, cover very little of gap between brilliant film and the framework, be created in framework and cover between the brilliant film as particulate, particulate can be stuck in and cover between brilliant film and the framework.If this situation takes place, the vibration in the LCD transportation will make particulate fray to cover the conductor part on the brilliant film, if impaired will the causing of lead shows bad problem.

Therefore, how to avoid particulate that the friction of covering brilliant film is become the industry problem demanding prompt solution.

Summary of the invention

Therefore, of the present inventionly provide a kind of micro-structural framework, be applicable in the module backlight with the liquid crystal indicator that covers brilliant film, micro-structural framework has a plurality of microstructures, microstructure is positioned at framework and covers brilliant film facing surfaces, when framework when covering brilliant film and contact, just fall in the microstructure at framework and the particulate that covers between the brilliant film.

According to one embodiment of the invention, microstructure is irregular alignment.

According to another embodiment of the present invention, microstructure is periodic arrangement.

According to further embodiment of this invention, microstructure be shaped as rhombus, circle, ellipse, triangle one of them.

Application the invention has the advantages that when framework when covering brilliant film and contact, just fall in the microstructure at framework and the particulate that covers between the brilliant film.The particulate that so just makes framework and cover between brilliant film can't produce friction to covering brilliant film, has avoided covering brilliant film by further scratch.

Description of drawings

For above and other objects of the present invention, feature, advantage and embodiment can be become apparent, being described in detail as follows of appended accompanying drawing:

Fig. 1 illustrates the partial structurtes synoptic diagram of LCD in the prior art;

Fig. 2 a illustrates the partial structurtes synoptic diagram of the LCD of the micro-structure adhesive tape that uses one embodiment of the invention; And

Fig. 2 b illustrates another partial structurtes synoptic diagram of the LCD of the micro-structure adhesive tape that uses one embodiment of the invention.

Embodiment

Please refer to Fig. 1, it illustrates the partial structurtes synoptic diagram of LCD in the prior art.Cover brilliant film 100 between housing 102 and framework 104, generally speaking, framework 104 and to cover between the brilliant film 100 be to exist gappedly, the gap is about 0.5 millimeter.After LCD assembling is finished, at framework 104 and cover that there are some particulates 106 in regular meeting in the gap between the brilliant film 100.Because the bending curvature of covering brilliant film 100 is difficult to control, and can't guarantees framework 104 and cover gap between the brilliant film 100 and can avoid particulate 106 and cover brilliant film 100 and produce and rub.

Therefore, as we know from the figure, work as external factor, for example transport the vibrations in the LCD process, make framework 104 and cover that brilliant film 100 contacts and when rubbing, particulate 106 just can be with the lead scratch of covering on the brilliant film, impaired lead can cause the bad problem of liquid crystal display displays.

Please refer to Fig. 2 a below, it illustrates the partial structurtes synoptic diagram of the LCD of the micro-structure adhesive tape that uses one embodiment of the invention.Cover brilliant film 100 between housing 102 and framework 104.A plurality of circular microstructures 200 that are periodic arrangement are arranged at framework 104 with covering on brilliant film 100 facing surfaces.Framework 104 and the gap of covering between the brilliant film 100 are about 0.5 millimeter.At framework 104 and cover in the gap between the brilliant film 100 a plurality of particulates 106 are arranged.

Please refer to Fig. 2 b this moment, it illustrates another partial structurtes synoptic diagram of the LCD of the micro-structure adhesive tape that uses one embodiment of the invention.Work as external factor, for example transport the vibrations in the LCD process, when making framework 104 and covering brilliant film 100 and contact, particulate 106 just can be fallen in the microstructure 200, and not can with cover brilliant film 100 and produce friction.

It should be noted that microstructure 200 also can be irregular alignment, and it is shaped as one of rhombus, circle, ellipse, triangle or any shape that can hold particulate 106.

Use the invention has the advantages that when framework 104 when covering brilliant film 100 and contact, just fall in the microstructure 200 at framework 104 and the particulate 106 that covers between the brilliant film 100.So just make framework 104 and cover brilliant thin 100 intermembranous particulates 106 and can't produce friction, avoid covering brilliant film 100, play a very good protection for covering brilliant film 100 by further scratches to covering brilliant film 100.

Though the present invention discloses as above with embodiment; right its is not in order to limit the present invention; any those of ordinary skill in the art; without departing from the spirit and scope of the present invention; when can being used for a variety of modifications and variations, so protection scope of the present invention is as the criterion when looking accompanying the claim person of defining.
