LCD substrate cleaning agent and using method thereof

Abstract

The invention discloses an LCD substrate cleaning agent and a using method thereof. The LCD substrate cleaning agent is prepared from the components in parts by weight: 10-20 parts of potassium hydroxide, 10-18 parts of sodium carbonate, 14-26 parts of ethanol amine, 15-25 parts of acetone, 15-25 parts of N-methylpyrrolidone, 5-10 parts of a non-ionic surface active agent, 5-10 parts of inorganicflocculant, 6-8 parts of a chelating agent, and 70-100 parts of deionized water. The using method includes the following steps of step 1 cleaning agent production, step 2 normal cleaning line, step 3cleaning with a cleaning agent, step 4 ultrasonic cleaning, step 5 substrate air-drying and step 6 UV light irradiation. The LCD substrate cleaning agent and the using method are scientifically formulated, synergistic effect of the surface active agent and various auxiliaries is used, good cleaning power is achieved while ensuring the uniformity of a film of the substrate, and wastewater treatmentis more secure. The multiple cleaning methods are more thorough, residues are rinsed clean, and the subsequent substrate display problem due to incomplete cleaning of a single cleaning method is avoided.

Description

technical field [0001] The invention relates to the technical field of LCD substrates, in particular to an LCD substrate cleaning agent and a using method thereof. Background technique [0002] LCD stands for Liquid Crystal Display. The structure of the LCD is to place a liquid crystal cell between two parallel glass substrates, set a TFT (thin film transistor) on the lower substrate glass, and set a color filter on the upper substrate glass, and control the liquid crystal molecules by changing the signal and voltage on the TFT. Rotate the direction, so as to achieve the purpose of controlling whether the polarized light of each pixel is emitted or not to achieve the display purpose. In the process of LCD production, the glass substrate needs to be fully cleaned to ensure the normal production of subsequent processes. At the same time, the existing cleaning method is single, which is not conducive to the sufficient cleaning of residues. Therefore, an LCD substrate cleaning ...

In the process of LCD production, the glass substrate needs to be fully cleaned to ensure the normal production of subsequent processes. At the same time, the existing cleaning method is single, which is not conducive to the sufficient cleaning of residues. Therefore, an LCD substrate cleaning agent and its application method are designed. is very necessary
