Embodiment Construction

[0022] like figure 1 , 2 As shown, a method for manufacturing an ITO heating sheet for a large-area LCD screen is characterized in that it is designed in a partitioned heating manner, and the entire ITO substrate is partitioned according to a certain area ratio by etching, and the ITO The size of the substrate is 9 inches × 24 inches, and the area ratio of the partition is 6:4:4:4:6, which specifically includes the following steps:

[0023] (1) Cleaning: First, clean the ITO substrate in an ethanol solution containing 4% KOH, then clean it with 95% ethanol, and finally rinse it with secondary water. After washing, place it in the air to dry naturally ;

[0024] (2) Coating photoresist: After evenly coating a layer of photoresist on the ITO substrate, put it in an oven and bake at 90-100°C for 25-30min;

[0025] (3) Exposure: The light emitted by the exposure machine is irradiated on the photoresist (RZJ-304) through the mask plate, and a photochemical reaction occurs; the p...

Abstract

The invention discloses a method for manufacturing an ITO heating plate for a large-area LCD screen. An area division heating mode is adopted for design, and an etching method is adopted for dividing a whole ITO substrate into areas according to a certain area proportion. Specifically, the method comprises the following steps of cleaning, resist coating, exposing, developing, ITO etching, electrode preparing and glue enveloping. The method has the advantages that the temperature field distribution of an ITO glass panel is uniform, the work effect of the LCD panel is good, and the working life of the LCD screen is prolonged.

Description

technical field [0001] The invention mainly relates to the field of large-area LCD screens, in particular to a method for manufacturing an ITO heating sheet used for large-area LCD screens. Background technique [0002] In view of the situation that LCD (Liquid Crystal Display) cannot work at low temperature, the ITO (Indium Tin Oxides) glass panel is used as the heating element as the heating element when the LCD is working. When the current flows through the ITO glass panel, the resistance of the ITO glass panel The heat generated by the LCD screen makes the LCD screen get heat, making the LCD meet the temperature requirements for working at low temperatures. At present, the heating of the large-area 1.5-inch LCD screen mainly uses a single whole piece of ITO glass substrate as a heating element. However, for a large-area panel, heating the entire panel will result in serious heat enrichment. The temperature in the middle of the panel is high and the temperature at th...
