Embodiment 1
[0031] like figure 1 , figure 2 As shown in the two-color display button, the material of the key cap 1 is transparent PC plastic; two kinds of fluorescent characters are printed on the bottom 2 of the key cap, and the characters are the number 8 and the letter A.
[0032] The two fluorescent characters are printed with two different inks. The two inks contain different fluorescent materials. The ink for screen printing number 8 contains Er 3+ Doped with Gd 2 o 3 5% up-conversion rare-earth fluorescent material in powder, Nd(OH) is contained in ink for mobile printing letter A 3 10% down-conversion rare earth fluorescent material in powder.
[0033] like image 3 As shown, the inks containing two kinds of fluorescent materials are printed in chronological order respectively ， First print the character 8, and then irradiate and solidify it with UV light, then print the latter character A, and then solidify it by heating.

Embodiment 2
[0036] Using a method similar to that of Example 1, 18 two-color display fluorescent buttons were produced, and combined together to form a two-color display control panel. Among them, there are numbers, letters or special symbols printed in each key, and each type of character is one or several, and different fluorescent characters are arranged in a misplaced manner, such as Figure 4 , 5 shown.
[0037] Characters containing large numbers and special symbols use a fluorescent material (Er 3+ Doped with Gd 2 o 3 ) ink printing form, characters containing capital letters with another fluorescent material (Nd (OH) 3 ) formed by ink printing.
[0038] When the fluorescent keyboard is irradiated with a light source in the infrared light area, large numbers and special symbols are highlighted, presenting a control panel 5 when irradiated with light of a wavelength; when the fluorescent keyboard is irradiated with a light source in the ultraviolet light area, the characters of...

Abstract
The invention provides a double-color or multi-color display button and a control panel thereof. According to the double-color or multi-color display button, one kind, or two kinds or various kinds of fluorescent characters are arranged inside a button cap or on the bottom of the button cap, fluorescent light in at least two colors is emitted by the button when the button is irradiated by two kinds or various kinds of light with different wavelengths, and the visual effect of figures, letters, Chinese characters, specific symbols and the like is enabled to be prominent through the fluorescent light. The fluorescent characters are formed by printing ink containing fluorescent materials in a silk-screen printing mode or in a movable printing mode. The proportion of the fluorescent materials in the printing ink is 0.1%-20%. The fluorescent materials are preferentially to be rare earth fluorescent materials. The printing ink containing two kinds or more kinds of fluorescent materials can be printed in sequence. The different fluorescent characters on the same button can be printed in a staggered mode or in an overlapping mode. Double-color or multi-color display control panels of a telephone, a mobile phone, a meter, a computer and the like can be formed by combination of the buttons, the number of the buttons which can be combined can be increased without changing circuits, different appearance effects can be achieved, and the number of functions is increased.
Description
technical field [0001] The invention relates to buttons for mobile phones, telephones, computers, instruments, etc., especially a fluorescent button that uses one, two or more fluorescent materials to receive light of different wavelengths to display two or more characters of different colors. Background technique [0002] With the continuous development of mobile phone technology, the functions of a mobile phone are becoming larger and larger, and the integrated camera, recorder, power amplifier, and amplifier can be seen everywhere. In addition, the addition of functions similar to computer keyboards makes the use of mobile phone keys more resourceful. nervous. At present, mobile phone buttons mostly use number keys and letter keys or function keys superimposed to solve the button resource problem, but often make the visual effect poor and have a dazzling feeling. In order to change the visual effect, the commonly used method is to use different light-emitting elements. W...
