subject: Guide bar, touch plate depth analysis [print this page] As laptop on two of the most common mouse control equipment, guide bar and touch boards friends unfamiliar, some fans are even for advice and touch boards works and a who protracted dispute. But to speak guide bar and touch the working principle, know board of friends may not be too many, so, stem and touch plate is how to work, they have what characteristics and advantages, let us see below.
ClassicLRRH: mouse directions
Little books mentionedlots of people will know in ThinkPad notebook appeared in a mouse control equipment, guide bar. In fact, dell, HP, SONY, Fujitsu, etc for many of the aircraft, the brand, we can also see guide bar. Especially in some commercial airplanes and super small thin models, due to guide bar of space is small, lighter weight, many models or even cancelled the traditional touch boards, and use only as a mouse guidance advice pole.
Guide bar are usually located in clavier "G", "H" and "B" button, and its control between key is located underneath the blank space key. In the guide stem usually installed an alternative to improve playability rubber cap, due to the use of the earliest IBM advice stem red color of a rubber cap, therefore, guide bar is also called "little red riding hood, and HP, dell laptop advice as pole is blue, black rubber cap.
Use directions of 2710P COMPAQ HP
Actually, the working principle of stem not complicated, it is on guide bar around four directions, such as setting sensor, guidance, advice when push rod of substrate due to the size of the force will be in a different direction of different deformation, ASUS UX50 Laptop Battery this will make Settings in different locations around the pole on the advice of the sensor for compression or expansion and produce different voltage, the voltage in the circuit into special processing, computer can learn advice on the size and strength, and the movement direction of arrow to control the mouse movement direction and speed.
Public level standard: capacitive touch boards
Relatively speaking, touch boards of a broader application in almost all we can see the notebook. Of course, touch boards are divided into various types, such as resistive touch boards, capacitive touch boards, surface acoustic touch boards, etc. Here, we talk about manufacturer USES most of the capacitive touch boards principle of work.
Our common touch boards by three layers, the upper structure of main function is to improve the operation touch boards antiwear properties, and gain good touch feeling, Layer is an electrode, densely reticular layers of metal structure with low-voltage high-frequency electric, But below the layer in the electrode is a sensor.
Touch plate internal structure and work principle
When the hand not exposed to touch boards, Replacement ASUS UX50 Laptop Battery electrode layer below the charge on the sensor to projection. When a finger close touch boards, due to human body, and the electrode wire in close point to form a part of high frequency current equivalent capacitance, is the equivalent capacitance flows, and points out corresponding to the current sensor will be reduced or disappear. So, when the finger movement, the sensor can disappear parts according to charge to know the direction of movement, and fingers will this signal processing chip and feeds back to control the mouse on the movement direction of the arrow.
Performance comparison: guide bar PK touch boards.
Performance comparison: guide bar touch boards. PK
In the actual performance, can guide bar and touch, and between the absolute superiority, it is both can coexist and disadvantages of long-term continuous reasons. If extortionary between them on a pole, then, is suitable for those who need for long-term use keyboard, and touch boards are more suitable for mass user and the dependence of weak population keyboard. Look, everyone will link to PK of these two kinds of control ways more understanding.
1 the bulk and weight
Guide bar:
Half the size of ZhiJiaGai hand lever in volume and weight undoubtedly the big advantage, especially small screen layout of notebook, promote, more reveal Pointers stem advantage.
Touch boards:
Touch boards can do small, but the small touch boards with ah, Battery For ASUS UX50 how to move the mouse arrow to pull a screen, finger several times, volume, touch boards forever of pain.
2 sexual accessible.
Guide bar:
For the friend's advice and guidance stem rod is absolutely nightmares, especially the acceleration function, often make beginners will not, and mouse arrow master, but it will guide bar for quite a long period of time.
Touch boards:
At this point, touch boards are obvious advantages, most of people to use the mouse can grasp the use of touch boards.
Three practical.
Guide bar:
Use directions, the user's hand lever, without leaving the keyboard in the whole process control, almost without moving, fingers so convenient, energy saving, natural to guide the operation in practical aspect, especially for those who often use the keyboard input text, more convenient.
Touch boards:
Cheap and easy to make touch boards become most laptops, even with the guidance of the earliest pole in the subsequent ThinkPad notebook, many of the machine, also have added touch plate design.
4.Sullpture series
Guide bar:
Due to the advice of a patent, and other company IBM to use and it must pay the patent is accessible, it is to a certain extent, the popularity of its ThinkPad model only appeared in the business or company and other high-end models.
Touch boards:
Cheap and easy to make touch boards become most laptops, even with the guidance of the earliest pole in the subsequent ThinkPad notebook, many of the machine, also have added touch plate design.
5 function expansion
Guide bar:
Due to the advice of small volume, the stem extensions are certain limits, say, guide bar only exists to replace the mouse.
Touch boards:
The touch of the plate is more flexible and expand as some manufacturers will give a touch boards handwritten, multimedia playback control, etc. But more touching even touch boards another important developing direction, flexible control and powerful function, make touch boards in the future might subverts the traditional definition of advice equipment.
