Embodiment Construction
[0013] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0014] After research, it is found that most of the waste LCD screens have only some damaged pixels, while their drive and backlight systems are intact, which can continue to play a role in the field of greenhouse farming. After the waste LCD screen is recycled, it is disassembled to remove the base, plastic shell and light guide plate, and then decomposed into LCD screen, driver board, power supply, side light and other parts. see figure 1 , the upper part of which is the plan view of the top of the greenhouse, install the LCD screen 2 on the bracket 1 on the top of the greenhouse; install the LCD driver board 3 on the bracket 1 below the LCD screen 2, and install the power supply of the LCD screen on the bracket 1 On the back side of the backside, the video lines of the LCD driver board 3 converge on the video distributor 4 through the wi...

The invention discloses a greenhouse lighting supplementing and shading system reconstructed of waste LCDs (liquid crystal displays). The system comprises a support forming a roof of a greenhouse. LCDs are arrayed on the support and are connected with LCD drive plates; the LCD drive plates are mounted on the support; video lines are led out from the LCD drive plates and are gathered to video distributors through a line duct within the support; the video distributors are connected to a video output interface of a master control computer; side lights are mounted on the inner side of the support; power lines of the side lights are connected with a power source through a side light controller; the side light controller is connected with the master control computer; a plurality of light sensors are distributed within the greenhouse. The greenhouse lighting supplementing and shading system has the advantages that the waste LCDs are recycled and mounted on the top of the greenhouse, light intensity is automatically adjusted to promote growth of plants, a comprehensive solution is provided for the income increasing problem of the greenhouse planting industry and the environmental pollution problem caused by waste electric devices, and the system has a huge market and considerable economic benefit.
Description
technical field [0001] The invention relates to the technical field of planting in greenhouses and recycling of waste electrical appliances, in particular to a lighting supplement and shading system for transforming waste liquid crystal screens into greenhouses. Background technique [0002] At present, liquid crystal displays have occupied an increasingly large display market. The display technology of liquid crystal displays is updated faster. Generally, many liquid crystal displays will face elimination in 5 to 10 years. Usually, liquid crystal displays are scrapped as a whole, and the maintainability is not high. Therefore, the chances of refurbishing as a second-hand product are minimal. With the increasing number of scraps year by year, the world is facing a severe problem of liquid crystal display recycling and disposal. The liquid crystal in liquid crystal display is biphenyl, which is a highly toxic pollutant. In addition, it also contains chromium, nickel, mercury ...
