preparation example Construction

[0019] According to the preparation method provided by the present invention, preferably, the metal particles are used in an amount such that the light transmittance of the metal layer is 5-60%. The inventors of the present invention have found through experiments that a metal layer with a light transmittance of 15-30% can be obtained by vapor-depositing 0.03-0.05 grams of metal particles per square centimeter of the substrate. Usually, when a vacuum evaporation machine with a diameter of 800 cm is used for evaporation, the amount of metal particles to be used is 0.01-0.08 grams.

[0020] According to the preparation method provided by the present invention, the conditions of the vacuum evaporation are well known to those skilled in the art, for example, the vacuum pressure of the vacuum evaporation is 1×10 -3 -8×10 -3 Pa.

[0021] Generally, when performing vacuum evaporation, three kinds of heating sources are usually used, namely resistance heating source, electron beam h...

Embodiment 1

[0054] This embodiment is used to illustrate the preparation of the display screen shell of the present invention

[0055] 1. Form a semi-transparent coating on the surface of one side of the substrate

[0056] 1) Primer coat

[0057] Mix and dilute primer crude oil (Cashew VM8000) (99%) and thinner (Cashew 9002) at a weight ratio of 1.5:1 to a viscosity of 8 seconds, spray on the cleaned shell substrate (polycarbonate (PC1414) The thickness is 2 mm, the light transmittance is 90%) on one side surface, then baked at 65 ° C for 8 minutes, and cured with ultraviolet light for 25 seconds, the energy is 1500 mJ / cm 2 , with an intensity of about 450 mW / cm 2 , to obtain a primer coating with a thickness of 16 microns (99% light transmittance).

[0058] 2) Metal layer

[0059] A vacuum coating machine (Taipei Vacuum, TPM-1618-36V-1) was used to vacuum evaporate the metal layer.

[0060] Tin particles are used as evaporation materials in a tungsten boat, and the two ends of the t...

Abstract

The invention relates to a display casing which casing comprises a substrate, a semi-transparent coating layer attached onto the surface on one side of the substrate and a light-tight coating layer attached onto the surface on the other side of the substrate, wherein the semi-transparent coating layer comprises a prime coat, a metal layer, a middle-paint layer and a finish paint layer from inside to outside in sequence, and the light transmittance thereof is less than or equal to 12 percent. Because the light transmittance of the transparent coating layer on the surface on one side of the substrate is controlled to be less than or equal to 12 percent, the display screen can be in a concealed state in case of no background lamp, that is, when an external light source (such as sunlight) only exists, the display screen and the appearance are integrated, so that the display screen has the concealing effect; and when an internal light source only exists, the contents on the display screen can be clearly seen, so that the function of the display screen is achieved.

Description

Technical field [0001] The invention relates to a display screen housing, a preparation method thereof and electronic products including the display screen housing. Background technique [0002] The display screens of current electronic products such as mobile phones and MP3 players can still clearly see the position of the display screen even when there is no signal display. When there is no light background, the display screen is kept in a hidden state. After turning on the background light, the effect of displaying the display content on the display screen cannot be achieved. Contents of the invention [0003] The object of the present invention is to overcome the inability of the prior art display screen casing to have a hiding effect on the display screen of electronic products, and to provide a display screen casing that enables the display screen of electronic products to have a hiding effect and a preparation method thereof and a display screen casing including the...
