Embodiment Construction

[0009] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0010] A method for reclaiming a TFT liquid crystal display with liquid crystal bubbles, comprising the following steps:

[0011] Check the appearance of the TFT LCD to make it free from broken appearance, cracks and defective plastic frames. Specifically, when checking product breakage and cracks, first check whether there are breakage and cracks on the TFT surface and CF surface of the product in the liquid crystal display area, and then check whether there are cracks or poor cutting on the cutting edge of the product TFT surface and CF surface. Finally, confirm whether the product has seals a...

Abstract

The invention provides a method for recycling a TFT (Thin Film Transistor) liquid crystal display with liquid crystal bubbles, comprising the following steps of: detecting the appearance of the TFT liquid crystal display to ensure that the TFT liquid crystal display has no broken parts, no cracks and no poor plastic frame; putting the detected TFT liquid crystal display into a hot drier for aging treatment, wherein conditions for aging are as follows: the temperature is 70 DEG C to 90 DEG C and the time is 40-60 minutes; storing the aged TFT liquid crystal display at low temperature, wherein conditions for low-temperature storage are as follows: the temperature is -50 DEG C to 0 DEG C and the time is 24 hours; storing the low-temperature stored TFT liquid crystal display at high temperature, wherein conditions for high-temperature storage are as follows: the temperature is 60 DEG C to 120 DEG C, the humidity is 50%RH to 100% RH and the time is 24h; and detecting the high-temperature stored TFT liquid crystal display, and collecting the TFT liquid crystal display without liquid crystal bubbles. According to the invention, the purpose of recycling is achieved by aging via roasting, low-temperature storage and high-temperature storage.

Description

technical field [0001] The invention belongs to the field of liquid crystal displays, and in particular relates to a method for recycling a TFT (Thin Film Transistor, thin film transistor) liquid crystal display with liquid crystal bubbles. Background technique [0002] There are few manufacturers of TFT liquid crystal display products, and the yield rate is not very high, so it is very important to recycle and utilize defective TFT liquid crystal display products. [0003] At present, the structure of an ordinary TFT liquid crystal display includes a TFT substrate and a CF (Color Filter, color filter) substrate arranged oppositely, and a first electrode layer and a second electrode layer are respectively provided on the opposite surfaces of the TFT substrate and the CF substrate. (generally ITO, indium oxide film), the first electrode layer and the second electrode layer are respectively provided with a first alignment layer and a second alignment layer, and the surrounding...
