Embodiment 1

[0039] refer to figure 1 , the present embodiment provides a ground glass 1 for an electronic blackboard, wherein a plurality of grooves 11 are arranged on the front of the ground glass 1 of the electronic blackboard, and the plurality of grooves 11 are spaced apart from each other, and the ground glass 1 of the electronic blackboard The parts between two adjacent grooves 11 on the front are on the same plane, and the area occupied by the multiple grooves 11 on the front of the ground glass 1 of the electronic blackboard is less than or equal to 10% of the front area of ​​the ground glass 1 of the electronic blackboard, for example but not It is limited that the area occupied by the plurality of grooves 11 on the front surface of the ground glass 1 of the electronic blackboard is 2% or 4% or 6% or 8% or 10% of the front area of ​​the ground glass 1 of the electronic blackboard.

[0040] In this embodiment, a plurality of grooves 11 are provided on the front of the ground glass...

Embodiment 2

[0044] refer to image 3 , this embodiment provides an electronic blackboard 2 .

[0045] The electronic blackboard, also known as the smart blackboard, enables chalk or pen blackboard writing and multimedia playback to be realized on one blackboard, and blackboard writing can be written on the entire blackboard including the multimedia playback area, and blackboard writing and blackboard writing can be realized without improving the external structure of the electronic blackboard. The switching of the display mode is more convenient than the traditional single blackboard or projector, and the display effect is better. The electronic blackboard surface is equipped with electronic blackboard frosted glass with a certain roughness on the surface, which can realize the function of writing on the blackboard. At the same time, due to the transparent characteristics of the electronic blackboard frosted glass, a liquid crystal module and a touch film are arranged between the electron...

Embodiment 3

[0051] This embodiment provides a frosted glass manufacturing method for manufacturing electronic blackboard frosted glass, refer to Figure 4 , Figure 5 and Figure 7 , the frosted glass manufacturing method comprises a mask covering step S1, a hydrofluoric acid etching step S2, and a tempering step S3; wherein, the mask covering step S1 refers to covering the front surface of the flat glass 4 with a plurality of open holes acid-resistant Mask 5; hydrofluoric acid etching step S2 refers to using hydrofluoric acid to etch the front of the straight glass 4 covered with acid-resistant mask 5, so as to corrode a plurality of grooves 11 on the front of the straight glass 4, more The area of ​​the front of the flat glass 4 occupied by each groove 11 is less than or equal to 10% of the front area of ​​the straight glass 4, such as but not limited to, the area of ​​the front of the flat glass 4 occupied by a plurality of grooves 11 is equal to or less than 10% of the front area of ...

Abstract

The invention provides frosted glass for an electronic blackboard, a manufacturing method for the electronic blackboard and the frosted glass, and relates to the technical field of electronic equipment. A plurality of grooves are arranged on the front of the frosted glass of the electronic blackboard, and the front of the frosted glass of the electronic blackboard is located between two adjacent grooves. The parts are on the same plane, and the area of ​​multiple grooves is less than or equal to 10% of the front area of ​​the frosted glass of the electronic blackboard; the electronic blackboard includes a substrate, a liquid crystal module, a touch film and the aforementioned frosted glass of the electronic blackboard; the liquid crystal module is connected to the front of the substrate; The touch film is connected to the back of the frosted glass of the electronic blackboard; the ground glass of the electronic blackboard is installed on the front of the substrate in such a way that the touch film faces and is spaced from the liquid crystal module; the method for manufacturing the frosted glass is used to manufacture the aforementioned frosted glass of the electronic blackboard. It alleviates the need to coordinate the writing fluency and display clarity of the frosted glass of the electronic blackboard in the prior art, so that the writing fluency and display clarity are not very good problems.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to an electronic blackboard frosted glass, an electronic blackboard and a method for manufacturing the frosted glass. Background technique [0002] In electronic equipment, electronic blackboard frosted glass with both display and writing functions is often used, such as electronic blackboard. With the development of large-screen display, touch control technology and the advancement of modern teaching, electronic blackboards equipped with frosted glass Blackboards are being used more and more widely in all walks of life, especially in the field of education. [0003] In order to achieve smooth writing, it is desirable that the roughness of the frosted glass of the electronic blackboard be as high as possible. It can be written smoothly, but the glossiness will decrease accordingly, which is not conducive to clear display. If the display is clear, the roughness cannot b...
