preparation example Construction

[0022] A preparation method of a reinforced liquid crystal display module heater, which comprises the following steps:

[0023] First, choose glass, plexiglass, PC, PMMA or polyimide film as the heater substrate. And it is cleaned to meet the subsequent preparation requirements;

[0024] Secondly, design the heating pattern shape on the substrate to meet the heating requirements; the heating pattern shape can be the overall shape consistent with the heater shape (such as figure 1 ), can also be formed by connecting several strips or block alloy materials ( figure 2 ), can also be a combination of bar and block patterns (such as image 3 ). A protective layer is applied, wherein the protective layer has a lower gasification temperature, and the temperature control of the film-forming interface is realized through gasification.

[0025] Third, using alloy materials as heating materials, through one or more of chemical vapor deposition, physical vapor deposition, mechani...

example 1

[0032] Select the optical glass of Shenzhen CSG Company as the substrate for the preparation of the heater, and cut it into a size of 60mm×60mm×1mm. Optical glass substrates were ultrasonically cleaned with isopropanol and pure aqueous solution for 5 min, followed by UV and ozone for 30 min. After the cleaning process, the optical glass substrate was plasma treated for 10 minutes in a vacuum not greater than 0.1 mTorr.

[0033] Coat a layer of low-temperature protective layer on the surface of optical glass by spin-coating process. Conventional protective materials can be used for the low-temperature protective layer. The thickness of the protective layer should be controlled between 10-30 microns, preferably 20 microns, and the thickness uniformity is about 98%.

[0034] Copper-chromium alloy sputtering and optical glass are used to form a film by physical vapor deposition process, the distance between the alloy target and the optical glass is adjusted to about 30cm, and the ...

example 2

[0037] Cut the constantan alloy foil laminated with polyimide film on one side to a size of 50mm×50mm, pre-fix it on a glass substrate of the same size, clean it ultrasonically with isopropanol and pure aqueous solution for 5 minutes, and then use UV and ozone Wash for 30 minutes. After the cleaning process, it is plasma treated for 10 minutes in a vacuum not greater than 0.1 mTorr.

[0038] Design the heating layer pattern and process the mask plate according to the requirements of the uniformity of the low-temperature heating temperature distribution of the liquid crystal screen of this size.

[0039] Then prepare the designed heating layer pattern by spin coating, photolithography, etching and other processes, use metal wire welding to lead out the heating electrode, and remove the pre-fixed constantan foil from the glass substrate to complete the preparation of the heater.

Abstract

A manufacturing method for a reinforcement type liquid crystal display module is characterized by including the following steps that firstly, glass is selected as a heater substrate to be washed; secondarily, a heating pattern shape is designed on the substrate and meets the heating requirement; thirdly, alloy material serves as heating material, and alloy material patterns are formed on the substrate through one or more combinations of a chemical vapor deposition method, a physical vapor deposition method, a mechanical rolling method and other methods; fourthly, electrodes are led out to a heating power supply from the alloy material patterns used for heating. The problem that in the process of low-temperature heating, liquid crystal screen temperature is not even in distribution is solved, so that heating efficiency is improved. The film forming technology, on substrate material poor in high-temperature performance, of the alloy material is achieved, and the application field of the alloy material is expanded. The problem that the irregular-shape liquid crystal display module is not even in temperature distribution in the process of low-temperature heating can be solved well.

Description

technical field [0001] The invention relates to a liquid crystal display technology, in particular to a liquid crystal display module heater technology, in particular to a preparation method of a reinforced liquid crystal display module heater. Background technique [0002] At present, due to the physical characteristics of liquid crystal molecules, the application of liquid crystal displays in low-temperature environments, especially in the field of liquid crystal display reinforcement, is limited to a certain extent. The research work aimed at improving the low-temperature operating characteristics of liquid crystal displays has always been one of the research priorities of various liquid crystal manufacturers and research institutes. [0003] For a specific liquid crystal display module, in a low-temperature environment, ITO (indium tin oxide) film heating components are generally used to externally heat the liquid crystal display module, which can basically solve the...
