Problems solved by technology

[0006] Glasses-free 3D tablet computers are attracting more and more people's attention. People can conveniently and realistically carry out entertainment, online games and other activities through glasses-free 3D tablet computers. However, the final product inspection before leaving the factory is very important , if the detection method is improper, it may also cause damage, and finally lead to a decrease in product yield

Embodiment Construction

[0022] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings:

[0023] like figure 1 As shown, a method for detecting a naked-eye 3D tablet computer includes the following steps:

[0024] S1, the selection of the detection environment, the ambient temperature for detecting the naked-eye 3D tablet computer is 25±5℃, the humidity is 65±10%RH, and the air pressure is 96±10KPa.

[0025] S2, detect the contrast, brightness and brightness uniformity of the LCD panel, such as image 3 As shown, five points P1, P2, P3, P4, and P5 are selected as detection points on the effective display surface of the LCD panel (the surface composed of H and V), where P5 is located at the center of the effective display surface of the LCD panel. On the dots, P1, P2, P3, and P4 are respectively located on the four corners of the effective display surface of the LCD panel, and the distance from the edge of the LCD panel is equ...

Abstract

The invention relates to a detection method for naked eye 3D tablet computers and belongs to the field of naked eye 3D tablet computer processing technologies. The method comprises the following steps that (S1) a detection environment is selected; (S2) the contrast degree, the brightness and the brightness uniformity of LCD panels are detected; (S3) the appearance of the computers is detected; (S4) reliability detection is performed, wherein after the detection, the change of current of the computers cannot exceed 50% of an initial value, and the computers of which the change of the current exceeding 50% are unqualified products; the step of reliability detection concretely comprises the following steps that (S41) high-temperature and high-humidity storage is detected; (S42) high-temperature storage is detected; (S43) low-temperature storage is detected; (S44) cold and heat impulsion is detected. The detection method has the advantages of being convenient and fast to operate, safe, reliable, high in yield and the like.

Description

technical field [0001] The invention relates to the technical field of naked-eye 3D tablet computer processing, in particular to a detection method for a naked-eye 3D tablet computer. Background technique [0002] The current naked-eye 3D technology can be divided into three types: light barrier type, cylindrical lens technology and directional light source. [0003] The realization method of the light-barrier 3D technology is to use a switching liquid crystal screen, a polarizing film and a polymer liquid crystal layer, and use the liquid crystal layer and the polarizing film to create a series of vertical stripes with a direction of 90°. These stripes are tens of micrometers wide, and light passing through them forms a pattern of vertical thin stripes called "parallax barriers." This technology utilizes the parallax barrier placed between the backlight module and the LCD panel. In the stereoscopic display mode, when the image that should be seen by the left eye is display...
