Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

The following detailed explanation and explanation of the embodiments of the present invention are provided with reference to fig. 1 to 5:

the utility model provides an anti-photoelectron blank, including blank 1 with set up in 1 frame 2 all around of blank, blank 1 is including the inferior light membrane 11, anti light curtain 12, touch-control circuit board layer 13, flannel layer 14 and the snow cover plate layer 15 that set gradually, anti light curtain 12 is the profile of tooth structure. The surface of the light-resistant curtain 12 is provided with a special prism structure, and specifically can be a sawtooth structure, in the use process of the anti-photoelectron whiteboard, ambient light can be absorbed, so that the condition that the color image of the anti-photoelectron whiteboard seen by a viewer is not real due to the influence of reflection or refraction and the like is prevented, the real pattern color can be restored, the better visual experience of the viewer is provided, the influence of other ambient light is avoided, and the eyestrain is not easily caused.

The light-resistant curtain 12 comprises transparent sections 121 and light-absorbing sections 122 which are arranged at intervals, wherein one end of the light-absorbing section 122 close to the flannelette layer 14 is higher than one end far away from the flannelette layer 14; the angle between the light absorbing section 122 and the horizontal plane is smaller than the angle between the transparent section 121 and the horizontal plane. With the structure, the color of the image projected by the white board 1 can be ensured to be clear and complete; since the ambient light, which is usually sunlight or lamplight, is located above the whiteboard 1, the light absorbing section can effectively absorb the ambient light.

The transparent section 121 is made of a PU material, and the light absorption section 122 is a black light absorption section. The transparent section 121 made of the PU material has low cost, and has the advantages of high strength, good toughness, good heat insulation performance and the like.

The light-resistant curtain 12 is connected with the touch control circuit board layer 13 through a double-sided adhesive tape 16. Through the mode that double faced adhesive tape 16 bonded, simple structure, convenient operation, and it is reliable and stable after the bonding.

The back of the snowfoil layer 15 is provided with a main control board 3 connected with the touch control circuit board layer 13.

The matte film 11 is made of a transparent PET material. The matte film 11 made of the transparent PET material has the advantages of good light transmittance, good creep resistance, fatigue resistance, abrasion resistance, good dimensional stability, small abrasion and high hardness.

The utility model discloses an anti-photoelectron blank, the surface of anti-light curtain 12 has special prism structure, specifically can be sawtooth structure in the anti-photoelectron blank use, can absorb ambient light, prevent that ambient light from causing the viewer to see because influences such as reflection or refraction are unreal such as the color image of anti-photoelectron blank, can restore real pattern color, experience for the better vision of viewer, and do not have the influence of other ambient light, be difficult for causing eyestrain.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and those skilled in the art can make many variations and modifications of the technical solution of the present invention without departing from the scope of the technical solution of the present invention.
