Problems solved by technology

[0005] In the above technical solution, the OLED light-emitting sheet is used as a backlight source, and the OLED light-emitting sheet emits light as a whole to illuminate the characters printed on the lower surface of the substrate, so that the characters of the entire keyboard can be displayed. Therefore, the light emitted by the light-emitting sheet needs to illuminate the entire substrate. Only the bottom surface can display the layout of the entire keyboard. The overall light-emitting area of ​​the light-emitting sheet is relatively large, and the area of ​​characters that need to be seen is small, so the power consumption is large, causing unnecessary waste

Embodiment 1

[0039] This embodiment provides a luminous button, such as figure 1 As shown, it includes an OLED light-emitting screen body, and the OLED light-emitting screen body includes an OLED substrate 1, and an anode layer 2, an organic electroluminescent layer 3 and a cathode layer 4 are sequentially formed on the surface of the OLED substrate 1, and the anode layer 2 and at least one layer of the cathode layer 4 is a transparent layer; the OLED encapsulation sheet 5 is arranged on the outer surface of the OLED light-emitting screen body, and is used to package the OLED light-emitting screen body as a whole; the anode layer 2 1. The three overlapping parts of the organic electroluminescent layer 3 and the cathode layer 4 are formed into a character shape, and the luminescent key emits light in the shape of a character and is transmitted through the anode layer 2 or the cathode layer 4 .

[0040] As an implementable mode, the anode layer 2 is in the shape of a character, and the catho...

Embodiment 2

[0048] In this embodiment, as a modification of Embodiment 1, a non-luminescent transparent material layer is filled outside the organic electroluminescent layer 3 in the OLED light-emitting screen body, so as to improve the contrast between the character shape and the non-character part on the key, Make the character shape easy to distinguish.

Embodiment 3

[0050] On the basis of embodiment 1 or embodiment 2, the present embodiment can be improved as follows, such as figure 2 As shown, a transparent contact layer 6 is arranged on the outermost layer of the light-emitting key. Therefore, the user directly taps the transparent contact layer during use, which can protect the OLED light-emitting screen body.

[0051] As a preferred embodiment, the transparent contact layer 6 is a transparent glass layer or a transparent plastic layer or a transparent resin material layer.

[0052] More preferably, a layer of phosphor powder is coated between the transparent contact layer 6 and the outermost layer of the luminous key, and the coating shape of the phosphor coincides with the character shape of the luminous key. Phosphor powder can be coated on the surface of the transparent contact layer 6 in contact with the outermost layer of the luminous key, or directly coated on the surface of the outermost layer of the luminous key, and then di...

Abstract

The invention discloses a light emitting key comprising an OLED (organic light emitting diode) light emitting screen body. The OLED light emitting screen body comprises an OLED base plate and an OLED encapsulation chip, wherein a positive pole layer, an organic electroluminescence layer and a negative pole layer are sequentially formed on the surface of the OLED base plate; the OLED encapsulation chip is arranged at the outer surface of the negative pole layer and is used for encapsulating the OLED light emitting screen body to a whole; and the positive pole layer or the negative pole layer or the organic electroluminescence layer is shaped like a character. The invention also discloses a keyboard utilizing the light emitting key. According to the light emitting key, only the character formed by a luminophor emits light, and therefore, the light emitting area is decreased greatly and the electric power is saved.

Description

technical field [0001] The invention relates to an information input device, in particular to a luminous key and a keyboard using the key. Background technique [0002] A keyboard is a common input device in our daily life, mainly used for command input of digital information devices, such as computer keyboards, mobile phone keyboards, etc. The fonts on computer keyboards that are widely used at present are generally printed by printing methods, and the printed fonts are easy to wear after long-term use and frequent knocking, and the fonts become blurred or even completely worn off; in addition, most of these keyboards They are all made of opaque plastic material, which cannot emit light by itself, and if in a dark area, the user cannot clearly see the font displayed on the keyboard, which brings inconvenience to the user. [0003] For this reason in the prior art, multiple methods for effectively preventing the font on the keyboard from being worn out have been proposed, s...
