Description

LCD polarized glasses test screen

Technical Field

The invention relates to the technical field of polarized glasses testing, in particular to an LCD polarized glasses testing screen.

Background

The LCD imaging technology is that liquid crystal is placed between two pieces of conductive glass, because the groove between the alignment films of the glass substrates deviates 90 degrees, the liquid crystal molecules become a twisted type, when the glass substrates are not added with an electric field, light rays penetrate through the polarizing plates to be twisted 90 degrees along with the liquid crystal, and the liquid crystal panel displays white through the lower polarizing plate; when an electric field is applied to the glass substrate, the liquid crystal molecules are aligned, light passes through the gaps of the liquid crystal molecules to maintain the original direction, the light is shielded by the polarizing plate below, the light is absorbed and cannot penetrate out, and the liquid crystal panel displays black. The LCD can achieve the display effect according to the voltage.

Present LCD polarisation glasses can produce some quality problems when production, for example the installation angle slope of polaroid to cause customer experience to descend, if can utilize LCD imaging principle to make the novel equipment that can short-term test wait the production defect of the LCD polarisation glasses of detecting just can solve this type of problem, for this we provide an LCD polarisation glasses test screen.

Disclosure of Invention

The present invention is directed to a LCD polarized glasses testing screen to solve the above problems.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a LCD polarisation glasses test screen, includes the shell, the rear end of shell is provided with the mainboard, install the singlechip on the mainboard, and install the memory with singlechip electric connection on the mainboard, the backshell is installed to the rear end of shell, and installs the speaker that links to each other with the singlechip on the mainboard, the rear end of mainboard is provided with SD card slot, and installs infrared transceiver on the mainboard, the shell has set gradually first polarizing film, liquid crystal glazing, second polarizing film and backlight unit by preceding to the back, and the center department of first polarizing film is provided with the inspection hole.

Preferably, the first polarizing film is a 0-degree polarizing film, the second polarizing film is a 90-degree polarizing film, and the detection hole is circular or regular polygonal.

Preferably, a filter plate is arranged on the liquid crystal glass.

Compared with the prior art, the invention has the beneficial effects that: the method can judge whether the installation angle of the polaroid on the LCD polaroid glasses to be detected is correct or not according to whether white blank strips exist between the images on the inner side and the outer side of the detection hole or not, and can judge the lens quality of the LCD polaroid glasses to be detected according to the difference of imaging quality between the images on the inner side and the outer side of the detection hole, so that unqualified products can be quickly screened out, and the method has high practical value.

Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a cross-sectional view of the structure of the present invention.

In the figure: the device comprises a shell 1, a SD card slot 2, a first polarizing film 3, a detection hole 4, a main board 5, a second polarizing film 6, liquid crystal glass 7, a backlight module 8, a memory 9, an infrared transceiving sensor 10, a loudspeaker 11, a single chip microcomputer 12 and a rear shell 13.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution for testing LCD polarized glasses: the utility model provides a LCD polarisation glasses test screen, which comprises an outer shell 1, the rear end of shell 1 is provided with mainboard 5, install singlechip 12 on the mainboard 5, and install memory 9 with singlechip 12 electric connection on the mainboard 5, backshell 13 is installed to the rear end of shell 1, and install the speaker 11 that links to each other with singlechip 12 on the mainboard 5, the rear end of mainboard 5 is provided with SD card slot 2, and install infrared transceiver sensor 10 on the mainboard 5, shell 1 is by preceding first polarizing film 3 to the back of having set gradually, liquid crystal glazing 7, second polarizing film 6 and backlight unit 8, and the center department of first polarizing film 3 is provided with inspection hole 4.

The first polarizing film 3 is a 0-degree polarizing film, the second polarizing film 6 is a 90-degree polarizing film, the detection hole 4 is circular or regular polygon, and the liquid crystal glass 7 is provided with a filter plate, and the single chip microcomputer 12 in the invention can adopt a common ARM single chip microcomputer which can analyze 720P videos or 1080P videos on the market, such as stm32 series single chip microcomputers.

When the invention works, a film is transmitted into the single chip microcomputer 12 through the SD card, the single chip microcomputer 12 utilizes the liquid crystal glass 7 to perform projection after decoding the film, as the first polarizing film 3 is cut off at the position of the detection hole 4, when the naked eye directly observes, the liquid crystal glass 7 corresponding to the detection hole 4 is pure white, and has no normal film pattern, when the liquid crystal glass 7 is observed through the LCD polarized glasses to be detected, if the polarizing sheet of the LCD polarized glasses is in a composite standard, a normal image which is completely connected with the image on the first polarizing film 3 appears at the position of the detection hole 4, when the polarizing sheet of the LCD polarized glasses to be detected has a problem, a white edge appears in the detection hole 4, thereby rapidly distinguishing whether the polarizing capability of the LCD polarized glasses is qualified, and through the contrast of the forming image quality of the images inside and outside the detection hole 4, whether the lens quality of the LCD polarized glasses is qualified can also be judged, therefore, the detection speed of the LCD polarized glasses is rapidly improved, and the method has high practical value.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
