Problems solved by technology

However, later experiments found that because the material of the acrylic plate is relatively hard, it will be deformed (bent) after being heated for a long time when it is attached to the LCD display panel. Causes damage to the LCD display panel

Embodiment 1

[0022] Example 1: Explosion-proof bonding of all glass substrates

[0023] Such as image 3 As shown, the top of the LCD display panel 1 is a liquid crystal display glass 2, and the liquid crystal display glass 2 is surrounded by the LCD display panel frame 3, and the area above the liquid crystal display glass 2 and in the middle of the LCD display panel frame 3 is the liquid crystal display area. The process of this structure is that 4-5mm thick frosted transparent tempered glass 12 is sequentially bonded with 2mil gray-black windshield film 11, touch film 10 and 3-4mm thick transparent soft crystal plate 9, and the display panel does not have any previous process, just When installed, it is directly combined with the transparent soft crystal plate 9 with a thickness of 3-4 mm, that is, the transparent soft crystal plate 9 with a thickness of 3-4 mm is embedded in the frame 3 of the LCD display panel.

[0024] The advantage is that the tempered glass has an explosion-proof ...

Embodiment 2

[0025] Example 2: Explosion-proof bonding of semi-glass substrates

[0026] Such as Figure 4 As shown, the top of the LCD display panel 1 is a liquid crystal display glass 2, and the liquid crystal display glass 2 is surrounded by the LCD display panel frame 3, and the area above the liquid crystal display glass 2 and in the middle of the LCD display panel frame 3 is the liquid crystal display area. The process of this structure is that 4-5mm thick frosted transparent tempered glass 12 is sequentially bonded with 2mil gray-black windshield film 11 and touch film 10, and the 3-4mm thick transparent soft crystal plate 9 is pre-embedded into the frame 3 of the LCD display panel. Then combine the two parts.

[0027] The advantage is that the explosion-proof function of tempered glass is retained, and the related process is relatively simple. Difficulty is the fixing method after the 3-4mm thick transparent soft crystal plate 9 is embedded into the frame 3 of the LCD display pan...

Abstract

The invention discloses an explosion-proof bonding type soft crystal interlayer fully-attached electronic blackboard with a glass substrate, which comprises an LCD display panel, liquid crystal display glass is arranged above the LCD display panel, the periphery of the liquid crystal display glass is wrapped by a frame of the LCD display panel, the area above the liquid crystal display glass, in the middle of the frame of the LCD display panel, is a liquid crystal display area, a transparent soft crystal plate is embedded in the liquid crystal display area in the middle of the frame of the LCDdisplay panel, and a touch control film, a gray black wind shielding film and frosted transparent toughened glass are sequentially adhered above the transparent soft crystal plate. According to the invention, a soft crystal interlayer form is adopted, so that the air gap can be completely eliminated, the writing characteristics of the frosted toughened glass are kept, the display is clearer, thepicture has higher light, the deflection of the frosted toughened glass is lower, the touch control is more stable, and the screen-off chromatic aberration is more consistent, and deformation damage of the LCD display panel can be effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of electronic blackboards, and relates to an explosion-proof bonding type soft crystal interlayer full-bonded electronic blackboard with a glass substrate. Background technique [0002] With the advancement of teaching modernization and the advancement of large-screen display and touch control technology, electronic blackboards are more and more widely used in all walks of life, especially in the field of education. The electronic blackboard includes a blackboard main board in the middle and blackboard sub-boards on the left and right sides. An LCD display panel is installed on the back of the blackboard main board. The sub-board of the blackboard is also called the writing board, which is used for writing with chalk; the display area of ​​the main board of the blackboard is mainly used for LCD display, which has dual functions of chalk and electronic writing. [0003] Due to the height difference between ...
