Embodiment

[0041] The four corners of the screen printing plate are used as the extended design of the screen-printed glass diffuser plate. The number of printings is set to 4 times. The first and third times of glass feeding are compared with the second and fourth times by 180° respectively. Obtain a glass diffuser plate with better appearance and optical effect, such as Figure 5 .

Abstract

The invention relates to the technical field of glass diffusion plate processing, in particular to a printing process for improving the brightness uniformity and picture effect of a glass diffusion plate. At least two layers of optical films are printed on the same surface of a glass substrate, all the optical films are overlapped to form a diffusion coating, and the printing mode of the optical films adopts a silk-screen printing mode. In the optical film printing process, the placing position of the glass substrate is at least horizontally turned once, the defect that the thickness of the diffusion coating is not uniform can be effectively overcome by changing the feeding mode of the glass substrate, and the overall uniformity of the diffusion coating is improved.

Description

technical field [0001] The invention relates to the technical field of glass diffuser plate processing, in particular to a printing process for improving the brightness uniformity and picture effect of a glass diffuser plate. Background technique [0002] Screen printing is a common process for preparing glass diffuser plates. The production of glass diffuser plates requires high printing uniformity, alignment, and no pinholes. At present, the demand for large-size printing (above 65 inches) is increasing, and for large-size In terms of coating uniformity and alignment accuracy of the screen printing process, the risk of defects such as pinholes increases, and the decrease in uniformity directly affects the optical performance of the diffuser plate. Contents of the invention [0003] In order to solve the problem of low uniformity of the coating of the glass diffusion plate in the prior art, the present invention provides a printing process for improving the uniformity of ...
