Problems solved by technology

[0002] At present, due to its non-mechanical flat structure and easy programming, touch screen technology is gradually being used more and more widely. Some people use touch screens to make keyboards for some communication and electromechanical products. But when applied to computers, how to make them more User-friendly, especially how to integrate the entire computer application system to make it more cost-effective without wasting the original investment is a problem

Embodiment Construction

[0019] For the convenience of description, a full dot-matrix reverse-white display LCD screen and a 104-key standard IBM PC keyboard are used as examples for illustration.

[0020] figure 1 Shown is a structural relational diagram of the combination of the touch screen and the liquid crystal display, the transparent touch screen is covered on the display screen, and the key symbols displayed on the display screen are projected through the touch screen.

[0021] figure 2 Shown is a standard 104-key keyboard layout, in the default state, the display will display as follows figure 2 The pattern shown for the standard keyboard layout.

[0022] image 3 Shown is the layout of the touch screen. The touch screen is correspondingly divided into 104 sensing areas, and the row and column electrodes are drawn out in a matrix relationship. Each sensing area is defined by a uniquely corresponding row and column.

[0023] like Figure 4 Shown, its working principle is, microprocessor...

Abstract

The invention discloses improved touch display screen type computer keyboard input equipment and an implementing method thereof. A touch screen and a display screen with backlight power-saving control form a main body of a computer keyboard, and the equipment comprises a correspondingly digital control circuit and an embedded management program to control the display of the touch keyboard and the switch of pictures thereof. The equipment can be directly applied in the current computer system without changing the primary computer system.

Description

technical field [0001] The invention relates to microcomputer software, hardware and interface technology, especially the technology of liquid crystal display and touch screen. Background technique [0002] At present, due to its non-mechanical flat structure and easy programming, touch screen technology is gradually being used more and more widely. Some people use touch screens to make keyboards for some communication and electromechanical products. But when applied to computers, how to make them more User-friendly, especially how to integrate the entire computer application system to make it more cost-effective without wasting the original investment is a problem. Contents of the invention [0003] The present invention integrates related electronic circuits and control systems, adopts touch display technology, avoids the troubles of dust and dirt, is easy to clean, and can dynamically display the key symbols and combinations to be used at the same time, providing an int...
