Description

Technical Field

[0001] The utility model relates to the technical field of electronic display equipment, in particular to a display equipment with tempered glass. Background Art

[0002] As the use cases of display devices expand, display devices with tempered glass are increasing day by day, especially in the field of commercial display, such as advertising machines, interactive smart tablets, smart blackboards, touch display terminals, etc., all need to add a piece of tempered glass in front of the LCD panel to improve the strength of the whole machine or provide a touch writing platform. In order to improve the display effect and reduce reflection, tempered glass is generally treated with anti-glare (AG). The core principle of surface AG is to reduce the smoothness of the glass surface, thereby reducing the direct reflection of light and reducing the generation of glare. Common types include spray-on AG and etch-on AG. Spray-on AG is to spray anti-glare materials evenly on the glass surface through spraying equipment to form a coating that can scatter light and reduce reflectivity; etch-on AG is to use chemical or physical methods to form tiny concave and convex structures on the glass surface. These structures can scatter reflected light, reduce direct reflection, and achieve anti-glare effects.

[0003] However, after the tempered glass is AGed, the LCD interface inside the whole machine tends to be blurred when viewed from the outside, which often gives people a feeling of unclearness. In addition, in a frame-mounted machine using a standard module, there is a large air gap between the LCD panel and the tempered glass, which will cause the display blur to increase and seriously affect the user's visual viewing experience. In addition, on a traditional frame-mounted machine, the LCD panel is vertically upright, and the thickness of the supporting blocks of the LCD panels on the sky side (i.e. the top) and the ground side (i.e. the bottom) are the same. As a result, when the whole machine is upright, the LCD panel is more likely to be in a concave state, resulting in an increase in the gap between the LCD panel and the tempered glass, thereby causing more serious visual blur. Utility Model Content

[0004] The technical problem solved by the utility model is to provide a display device with higher definition and tempered glass.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a display device with tempered glass, including a module back shell, a module optical component, a module rubber frame, a first support block, a first buffer pad, an LCD panel, tempered glass, a second support block, a second buffer pad and a module face frame, the module optical component is installed on the inner side of the module back shell, the module rubber frame is installed at the opening of the module back shell, the first support block is installed on the upper part of the module rubber frame, the second support block is installed on the lower part of the module rubber frame, the thickness of the first support block is greater than the thickness of the second support block, the first support block and the second support block respectively contact the back side of the LCD panel, the module face frame is connected to the module rubber frame, the first buffer pad and the second buffer pad are provided on the module face frame, the first buffer pad is arranged corresponding to the first support block, the second buffer pad is arranged corresponding to the second support block, the first buffer pad and the second buffer pad respectively contact the front side of the LCD panel, the LCD panel is arranged at an acute angle with the vertical direction, and the tempered glass is installed on the module face frame.
