Description

The detection method of bore hole 3D panel computer

Technical field

The present invention relates to bore hole 3D panel computer processing technique field, particularly relate to a kind of detection method of bore hole 3D panel computer.

Background technology

Current bore hole 3D technology can be divided into optical barrier type, lens pillar technology and directional light three kinds.

The implementation method of optical barrier type 3D technology is use switching Liquid Crystal screen, polarizing coating and high molecule liquid crystal layer, utilize liquid crystal layer and polarizing coating to produce vertical stripes that a series of direction is 90 °.These stripeds are wide tens microns, just define vertical slice grid pattern, be referred to as " parallax barrier " by their light.And this technology make use of the parallax barrier be placed between backlight module and LCD just, under stereoscopic display mode, when the image should seen by left eye is presented on liquid crystal display, opaque striped can block right eye; In like manner, when the image should seen by right eye is presented on liquid crystal display, opaque striped can block left eye, by by the viewable pictures of left eye and right eye separately, makes onlooker see 3D image.

Lens pillar technology is also referred to as microtrabeculae lens 3D technology, and what make liquid crystal display is positioned on the focal plane of lens as plane, and the pixel of the image like this below each post lens is divided into several sub-pixel, such lens just can with different direction projections each sub-pixel.So eyes, from different angles viewing display screen, just see different sub-pixels.

Directional light 3D technology is substantially similar with above-mentioned display technique in displaying principle, needs two pieces of background light sources unlike this technology when presenting 3D picture.When the right and left eyes of spectators receives picture simultaneously, place's background light source in different directions is alternately lighted successively, alternately in face of spectators, presents right and left eyes picture through 3M reflectance coating.Because human eye has certain suspenopsia time, so the picture alternately occurred just can form 3D picture in human brain.

Bore hole 3D panel computer more and more receives the concern of people, people can by bore hole 3D panel computer convenient and true to nature carry out the activity such as amusement, online game, but, detection before product export last in bore hole 3D panel computer manufacturing process is most important, also may cause damage if detection method is improper, finally cause finished product rate to reduce.

Summary of the invention

In order to solve the problems of the technologies described above, the object of this invention is to provide a kind of safety, yield rate detection method that is high, bore hole 3D panel computer easily.

The object of the invention is to be achieved through the following technical solutions:

A detection method for bore hole 3D panel computer, comprises the steps:

S1, the selection of testing environment;

S2, detects the contrast of LCD, brightness, luminance uniformity;

S3, detects the outward appearance of computer;

S4, reliability detects, and after detection, the change of computer electric current can not exceed 50% of initial value, and what exceed is unacceptable product, specifically comprises the steps:

S41, detects hot and humid storage;

S42, detects high temperature storage;

S43, detects low temperature and stores;

S44, detects thermal shock.

By the technical scheme of the invention described above, method of the present invention has simple operation, safe and reliable, yield rate high.
