Refrigerator door with semi-transparent liquid crystal light-emitting structure and manufacturing method thereof

Abstract

The invention provides a refrigerator door with a semi-transparent liquid crystal light-emitting structure and a manufacturing method thereof. The refrigerator door with the semi-transparent liquid crystal light-emitting structure comprises a door frame, a liquid crystal display module, front plate glass, rear plate glass and an aluminum strip, wherein the front plate glass and the rear plate glass are arranged in the door frame in a spaced mode; the liquid crystal display module and the aluminum strip are arranged between the front plate glass and the rear plate glass. The refrigerator door has the following beneficial effects that a liquid crystal display technology combining a transparent liquid crystal screen and a semi-transparent backlight source is adopted; a light guide plate in the backlight source and with an optical micro structure can reflect out ultra-high brightness white light emitted by lateral light LED light strips on the periphery of the light guide plate in two directions; according to one direction, the light is reflected outwards from the front surface of the light guide plate, so that a white light backlight source with proper brightness and uniform light is provided for the liquid crystal display screen, words displayed by the transparent liquid crystal screen are clear, images displayed by the transparent liquid crystal screen are vivid in color, and the display quality is greatly improved.

Description

technical field [0001] The invention relates to a translucent liquid crystal display technology, in particular to a translucent refrigerator door with a translucent liquid crystal light-emitting structure and a manufacturing method thereof. Background technique [0002] Applying transparent liquid crystal display technology to freezers and freezers to form a new type of commercial and supermarket advertising display equipment has become a hot new idea in the world in recent years. The current technology is to install a transparent LCD screen in the glass door of the refrigerator. When a transparent signal is given to the LCD screen, people can see the actual goods displayed in the refrigerator through the door of the refrigerator. The product information and advertising videos dynamically displayed on the website have a good rendering effect of the exhibits, giving people a refreshing feeling. The LCD screen can display color images, but the LCD screen itself does not emit ...

Problems solved by technology

However, in the current transparent liquid crystal display refrigerators, the backlight used to display the image of the LCD screen is only the lighting light in the refrigerator. These lighting sources are installed on the top and two sides of the refrigerator, and cannot provide effective frontal lighting for the displayed products. , in order to increase the perspective brightness, the lighting power must be increased, but the heat emitted by the lighting strip will increase the temperature in the refrigerator, causing the refrigerator to work frequently, increasing energy consumption and shortening the service life of the equipment

At the same time, the reflected light from the various commodities placed discretely in the freezer to the transparent LCD screen is like providing a backlight with uneven brightness and dark colors and mottled colors for the transparent LCD screen, which makes the text displayed on the transparent LCD screen difficult to see clearly. The color of the image is distorted, and the quality of the LCD display is greatly affected
