Structure and method for reducing height of full plane display cover plate

Abstract

The invention discloses a structure and method for reducing the height of a fullplane display coverplate. Thestructure comprises the cover plate, a panel and a panel back part. The cover plate is connected and fixed on the front end surface of the panel by a tape, and the panel back part is connected to the back of the panel.Fixing partsare fixedly connected to a non-display area on at least one opposite side of the back side of the cover plate, connecting portions are arranged the positions, corresponding to the fixing parts, of the panel back part, and gapsare reserved between the connecting portions and the fixing parts.The connecting portions and the corresponding fixing partsare connected through quick-release connecting parts in locking and attaching modes, the gaps between the connecting portions and the corresponding fixing parts are compensated, and the cover plate is pulled to move towards to the direction of thepanel back partand to be deformed. The distance between the cover plate and the panelcan be greatly reduced, and the visual effect and the touch experience areimproved.

Description

Technical field [0001] The present invention relates to the field of displays, in particular to a structure and method for reducing the height of a full-plane display cover. Background technique [0002] There are generally two assembly methods for full-flat displays with touch modules or protective covers on the market, one is direct bonding and the other is air bonding. However, the cost of direct bonding is much higher than that of air bonding. Air bonding is still the main market in the market. As the size of the display becomes larger and larger, the application of air bonding becomes more extensive. [0003] Air bonding, as the name implies, means that there is an air layer between the cover and the panel. The air layer serves two purposes. The first is to prevent the cover from deforming and contacting the surface of the panel to form a Newton ring when the panel is touched. When the control cover is pressed, it will cause the cover and the panel to attract; the second is t...

Problems solved by technology

Based on the above reasons, the height of the air layer has become a design limitation and challenge

[0004] The height of the air layer will have the following effects: If the air layer is too high: 1. The thickness of the product will increase, which will affect the appearance; 2. If there is too much air layer in the middle, it will easily accumulate water vapor content, which will increase the condensation of water vapor on the inner surface of the cover and affect the vision. and touch operation; 3. Reduce the light transmittance of the panel; 4. Increase the sense of touch deviation

The air layer is too low: 1. The deformation of the cover causes the contact between the cover and the panel, forming a Newton ring, which affects the vision; 2. The touch cover touches the panel, resulting in abnormal touch function
