Design method of PASSIVE product color screen printing based on optimal visual angle

Abstract

The invention relates to a design method of PASSIVE product color screen printing based on an optimal visual angle. The method comprises the following steps of determining whether a silk-screen printing format belongs to monochrome or polychrome; judging the thickness H of the glass and the viewing angle range theta; obtaining the data d' according to a table; calculating the space distance D between the two ICON patterns according to a monochrome screen printing formula or a polychrome screen printing formula; reserving a designed silk-screen size X and the space distance according to the distance D. According to the method, a quantifiable calculation formula is mainly designed as the design reference for the project early-stage planning, so that the design timeliness is improved, the repeated modification cost of a mold is reduced, the specific quantifiable data formula is creatively used as the design reference, the defect of repeated modification of the mold at the later stage is effectively overcome, and the production and design cost is greatly reduced.

Description

technical field [0001] The invention belongs to the field of PASSIVE LCD display, in particular to a design method for color silk screen printing of PASSIVE products based on the best viewing angle. Background technique [0002] At present, PASSIVE LCD is widely used in various display fields, especially in vehicle products, but the traditional monochrome display can no longer meet the requirements of users. Now the car manufacturers have introduced one or more LEDs based on white backlight on the back of the traditional monochrome display. A variety of color printing to make the instrument more personalized. [0003] The screen printing pattern outside the box is to print various decorative color graphics on the designated position of the LCD screen by screen printing. This process is only processed when the customer has this special requirement, but for the color printed pattern How to design the size can ensure that there will be no light leakage within the viewing angle...

[0003] The screen printing pattern outside the box is to print various decorative color graphics on the designated position of the LCD screen by screen printing. This process is only processed when the customer has this special requirement, but for the color printed pattern How to design the size can ensure that there will be no light leakage within the viewing angle required by the customer; in the current design, we generally only consider the silk screen printing process capability of the factory, and do not consider factors such as the actual viewing angle of the product, the refractive index produced by different glass thicknesses, etc. As a result, we did not have a unified theoretical basis for reference as to the distance between the silk screen pattern and the adjacent pattern in the early design, and we could not provide a strong basis for our customers to recognize the necessity of this modification. This disadvantage often requires constant modification of the design and repeated verification, which seriously affects the design timeliness and wastes mold modification costs.
