A semi-transparent LCD polarized glasses test screen display cabinet

Abstract

The invention discloses a semi-transparent LCD polarized glasses test screen display cabinet, which comprises a display cabinet body, a display rack is arranged inside the display cabinet, a backlight module is arranged inside the display cabinet, and the display cabinet at the upper end of the backlight module There is an LED light strip on the body, and a liquid crystal module is arranged on the outside of the display cabinet, and the liquid crystal module is driven by a matching main board. The structure of the present invention is based on the principle of LCD display, using the characteristics of cross-polarized light filters to realize a simple product for the authenticity of polarized glasses. When the polarized glasses are sold, the display characteristics of the LCD screen are used. Remove the upper polarizer or do not retain the full area of ​​the upper polarizer to create a high-quality dynamic color image for customers. In this case, use a semi-transparent LCD screen for product display. For LCD screens, it is the identification of the eyewear industry. Provide high-quality customer experience and anti-counterfeiting functions in use, promotion and display.

Description

technical field [0001] The invention relates to the field of polarized glasses testing, in particular to a semi-transparent LCD polarized glasses testing screen display cabinet. Background technique [0002] LCD imaging technology is to place the liquid crystal between two pieces of conductive glass, driven by the electric field between the two electrodes, causing the liquid crystal molecules to twist the electric field effect of the nematic, so as to control the transmission or shielding function of the light source, and generate light and darkness between the power on and off And the image is displayed, if a color filter is added, a color image can be displayed. Install a pair of crossed polarizing films on the two glass substrates, so the liquid crystals will align along the grooves. Since the grooves of the alignment film on the glass substrates deviate by 90 degrees, the liquid crystal molecules become twisted. When the glass substrates do not add an electric field, the...

Problems solved by technology

[0003] There are many types of polarized glasses on the market, but there are very few effect monitoring devices. After buying polarized glasses, many users find that the display effect cannot meet the advertised effect. Therefore, we propose a semi-transparent LCD polarized glasses test screen display cabinet is used to solve the above problems
