Background technology

Along with development of science and technology, the science and technology Communication Equipment is an instrument of quite popularizing, such as mobile phone, personal digital assistant (PDA:personal digital assistant), palmtop computer all belongs to this type of, button then is the indispensable part of scientific and technological Communication Equipment, the prior mobile phone key device as shown in Figure 4, on a light guide plate 50, be provided with rubber key 51 (or film key), light guide plate 50 has circuit board 52, circuit board 52 is provided with several light-emitting diodes 53, when the user contacts rubber key 51 (or film key), can make all light-emitting diodes 53 luminous by circuits for triggering plate 52, by light guide plate 50 light is located to appear from rubber key 51 (or film key), mobile phone key device (or the household appliances button of another kind of form, the automated production button, machinery or instrumentation panel etc.) as shown in Figure 5, former rubber key 51 outer layer of metal or the nonmetal film formation plated film buttons 511 of plating.

Also have a kind of be commonly used on the PDA(Personal Digital Assistant) the touch-controlled key device as shown in Figure 3, it is configured in a light guide plate 60 and is provided with down indium oxide layer of tin (ITO) 61, have indium oxide layer of tin 63 at a touch panel 62 in addition, last indium oxide layer of tin 63 and 61 peripheries of following indium oxide layer of tin are provided with can be with both and the wall 64 to be spaced apart, be provided with several spaced points 65 on the indium oxide layer of tin 61 down, be provided with LCD 66 under the light guide plate 60, when the user uses finger or style of writing press contacts panel 62, touch panel 62 presses down indium oxide layer of tin 63 is contacted with following indium oxide layer of tin 61 by spaced points 65, it is luminous that trigger LCD 66 this moment, and light appears via touch panel 62 by light guide plate 60.

More than three kinds of existing key devices, its common shortcoming is that thickness is blocked up, become the obstruction of pursuing under the compact trend, in addition, as Fig. 4 and existing key device shown in Figure 5, because use a plurality of light-emitting diodes, can raise the cost, power consumption and leaded light intensity are inhomogeneous, plated film button 511 as shown in Figure 5 increase the difficulty of making because of the homogeneity of coating is wayward, and the plating thing can cause environmental issue when reclaiming on making, existing apparatus as shown in Figure 3, because used LCD, so can raise the cost, the above is the shortcoming of existing apparatus.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art and defective, and it is single and simple to design a kind of processing procedure, and thickness is little, and cost is lower, and the key device that can not pollute when reclaiming.

For reaching above-mentioned purpose, the utility model designs a kind of touch panel button, comprising a touch panel and with respect to the light conductor of its position, touch panel one side forms the indium oxide layer of tin, in addition one form on respect to the light conductor of touch panel position under the indium oxide layer of tin, the inboard periphery of this two interlayer is provided with the wall that both can be separated and joins with last indium oxide layer of tin and following indium oxide layer of tin respectively, be provided with several spaced points on the indium oxide layer of tin down, one end is provided with a reflectance coating in the following indium oxide layer of tin outside, reflectance coating one end forms jut, the other end is provided with a light-emitting diode, touch panel is the button end with respect to reflectance coating one end, with respect to liquid crystal indicator one end is display end, as user during with the button end of hand or style of writing control touch panel, but reach indium oxide layer of tin down by indium oxide layer of tin in the spaced points conducting, can make lumination of light emitting diode, the light that this moment, light-emitting diode sent reflexes to touch panel via reflectance coating and outwards appears, the jut light that makes light-emitting diode that can obstruct the light does not interfere with each other with the light of liquid crystal indicator, the user can see the button of button end by the light that reflects, and the result after pressing button can be presented at display end via liquid crystal indicator.

Advantage of the present utility model is that processing procedure is single and simple, and the use touch panel combines with reflectance coating, can reduce thickness, utilize the lumination of light emitting diode of minute quantity, the effect that can reach input or show can reduce cost, and the recyclable pollution that promptly can not cause environment of the utility model.
