Key structure of touch panel and method of use thereof

Abstract

This invention discloses one touch module key structure and its method for cell phone handle digital codes, wherein, Touch board key structure is imbedded with mechanic keys in touch key to realize dial photon function; the key is realized through spring metal spring; due to the metal slice its dial has key sense. This invention can realize above function operation and determination function based on above hardware metal spring.

Description

technical field [0001] The invention relates to a key structure of a touch panel, and also relates to a method for respectively realizing dialing, navigation, mouse operation and multimedia browsing by using the key structure, which is suitable for hand-held digital products such as mobile phones. Background technique [0002] At present, the input keyboards of mobile phones generally include two types. One is a mechanical keyboard. Two-stage feel, but the disadvantage is that the keyboard surface cannot realize handwriting and touch input. The other is a touch panel keyboard, as shown in Figure 2, which is mainly connected by a capacitive / resistive touch sensor to the PCB through a connector. Use a pen or finger to touch the sensor, detect the position of the point through the circuit, and use a special The software implements function input, but the disadvantage is that it lacks the two-stage feel of pressing the button, and because there is no pressing feel, sometimes it...

Problems solved by technology

[0002] At present, the input keyboards of mobile phones generally include two types. One is a mechanical keyboard. Two-stage feel, but the disadvantage is that the keyboard surface cannot realize handwriting and touch input

The other is a touch panel keyboard, as shown in Figure 2, which is mainly connected by a capacitive / resistive touch sensor to the PCB through a connector. Use a pen or finger to touch the sensor, detect the position of the point through the circuit, and use a special The software implements function input, but the disadvantage is that it lacks the two-stage feel of pressing the button, and because there is no feeling of pressing, sometimes it is not clear whether to press the button, resulting in repeated buttons, which is not conducive to the use of nearsighted or blind users.

[0003] In addition, in the Chinese utility model patent announcement number CN2565217Y, the announcement date was August 6, 2003, and the name is "upright mobile phone with keyboard and touch screen", a mobile phone with keyboard and touch screen is disclosed. The mechanical keyboard also has a touch screen, but its disadvantage is that the keyboard and the touch screen are separated, and the display screen and the touch screen use the same screen. When the touch screen is used, the effective display range of the display screen is very small

[0004] The current handheld digital products such as PDA mobile phones are designed according to the idea of ​​two-handed operation. Except for a few shortcut keys, most of the main function operations, such as dialing and text input, need to be done through the touch screen. For operation, this two-handed operation mode loses the convenience of one-handed operation of traditional mobile phones, which brings inconvenience to users

[0005] In addition, in the operation of the mobile phone, functions such as mouse operation and multimedia file browsing are rarely involved.
