Problems solved by technology

[0008] However, due to the greater difference between the newly replaced LEDs and the used LEDs in "instant characteristics" and "attenuation characteristics", it is necessary to repeatedly replace and debug many times before it is possible to find an optical parameter similar to that of the LED array in the original backlight unit. LED substitutes, this maintenance method has a long maintenance period and high randomness, it is difficult to control the maintenance period, the maintenance personnel are prone to fatigue, the maintenance effect varies from person to person, and it is difficult to achieve a unified maintenance standard in the end

Abstract

The invention discloses an LCD double side display device, which comprises an image signal interface, a user operation interface, a liquid crystal drive unit, at least two liquid crystal units, a central processing unit, an LED backlight control unit, an LED backlight unit, and a maintenance communication interface, wherein the maintenance communication interface is connected with the central processing unit, used for receiving external maintenance data and sending the external maintenance data to the central processing unit, and also used for transmitting status data of the LCD double side display device in the central processing unit to outside. In addition, the invention also discloses a maintenance system and a maintenance method for the LCD double side display device. The proposal of the invention can adjust the LED backlight unit of the LCD double side display unit under the condition of no-disassembly of the machine.

Description

technical field [0001] The invention belongs to the technical field of LCD double-sided display devices, and in particular relates to an LCD double-sided display device, a maintenance system and a maintenance method thereof. Background technique [0002] In the display, the cathode ray tube CRT once occupied the entire market, but due to its weight and scale limitations, it cannot meet the trend of miniaturization and light weight of electronic products. Currently, a small and compact display device is needed to replace the CRT display. Later, with the research on display technology, liquid crystal display LCD can realize the display function of replacing CRT with its advantages of small size, light weight and low power consumption. With the in-depth research on LCD, it has been widely used in flat panel displays and personal In display terminal equipment such as computers, and the market demand for LCD is increasing year by year. [0003] Since the LCD is a passive display...
