Touch panel Character LCD Modules

Hardness
Resistive surface layer is PET (plastic) material, usually hardness is 3H, here the so-called H pencil hardness is hardness, for example, like 2B, HB pencil and the like, we use a pencil all know that the pencil is very easy to break, plus the aging plastic becomes brittle, resistive touch panel is very easy to damage the resistance is better PDA or other personal use items, then, usually we will be very care of their things, but if public, then, it is easy because they do not care to use or improper use of the destruction, usually caused by the troubled vendor maintenance, let alone customers the opportunity cost of lost because the machine can not be used.
3M surface capacitive touch panel using 3M exclusive HardCoat, capacitive touch panel allows the hardness of the surface of glass, Mohs rating from one to ten, the hardest level is 10: Diamond. Capacitive touch panel is very suitable for use in a variety of occasions, because The hardness of 7Mohs can easily qualified for a variety of applications and user devastated.
Accuracy
PET innate physical characteristics resistive best accuracy only to 98.5% (ie error of under 1.5%), while the capacitive touch panel at current drive, the accuracy rate can reach 99% (ie error value 1 %). Did not feel this difference of 0.5% in the small size to large size, the 0.5% gap may be the area of ​​a button may cause malfunction.40x2 lcd
The reaction time
If only single-point touch, reaction time and perhaps do not feel out of it with importance, but if you need to draw a line, such as the use of game consoles, it is very important, capacitive, so a timely response, you use resistance -so is a feeling there will be slow to keep up with the rhythm of the game. 3M's new generation of capacitive capacitive touch screen ClearTek II, for example, as long as with the 3M EX II control card, you can achieve only 3 ms touch response time.
Touch RBI life
We usually can be said to represent the touchscreen is * and durability, capacitive touch RBI life far more than other resistive technology, of course, such a superior touch RBI life is due to the 3M exclusive Hardcoat protect the condenser surface. The touch panel and durability is higher, the less need of repair and warranty costs, the condenser for consumers is a very cost-effective solution for all costs.
High-temperature operation
As CPU speed faster and faster, the CPU is also increasingly hot, plus the heat and light of the LCD panel, the entire system cooling is an increasingly important technical issues, capacitive high temperature tolerance than the resistive 20C, in the system design can be more convenient, but also can be used in some special circumstances.display lcd 20x4
Anti-UV
PET is not UV-resistant, and therefore the resistance type is not suitable for long-term outdoor use. The capacitive and they were not afraid UV plus before resistive high temperature operation, more suitable for outdoor accepted the sun's wind and sun.
