Description

An organic light emitting diode key structure

technical field

Background technique

At present, common physical buttons are mainly used to realize relevant commands by pressing them by hand. These buttons themselves do not have the function of displaying commands and execution results. And the organic light-emitting diode button (that is, the OLED button) was born accordingly. Organic light-emitting diode buttons have thin, pressable, displayable and even integrated display functions (multiple screens form the same screen to achieve free size and layout), and are widely used in monitoring devices, vehicle equipment, airborne equipment, medical equipment, etc. Organic light-emitting diode buttons use the smallest organic EL display screen with high-quality color display small screen, and realize high-speed synchronous communication through the use of SPI communication interface. In the organic light-emitting diode key structure in the prior art, the organic light-emitting diode display screen is installed on the key body itself, and the key cover layer is fixedly connected to the upper surface of the key body through a connecting adhesive layer. Such a structure cannot meet the actual needs in terms of strong light visual function, strong vibration resistance, anti-fog performance, and meeting the requirements of a low-pressure working environment. Therefore, the performance of the organic light emitting diode key structure is affected as a whole. Because the key cover plate in the prior art on the market is made of plastic material, its transmittance is low, without anti-reflection treatment, the reflection is large, so strong light cannot be realized; the key cover plate and the key body are fixed only through the surrounding adhesive layer Fixed, when environmental conditions such as temperature difference and air pressure change, due to the difference in material expansion coefficient and the difference in internal and external pressure, the cover plate will automatically fall off; and the fixed surface is flat, its lateral vibration can only be effectively fixed through the adhesive layer, and it is easy to shift and fall off. It cannot withstand strong vibration; since the middle is an air layer, water vapor has formed in the inner layer of the cover when the temperature difference changes, which cannot achieve the effect of waterproofing and fogging; thus it cannot meet the performance requirements.
