capacitive touchscreen vs tft lcd for sale
There are many types of touch panel technologies available in the market, the popular types are we are going to discuss the two most widely used types, and compare resistive vs capacitive touch screen
Projected Capacitive Touch Panel (PCAP) was actually invented 10 years earlier than the first resistive touchscreen. But it was no popular until Apple first used it in iPhone in 2007. After that, PCAP dominates the touch market, such as mobile phones, IT, automotive, home appliances, industrial, IoT, military, aviation, ATMs, kiosks, Android cell phones etc.
Projected capacitive touchscreen contains X and Y electrodes with insulation layer between them. The transparent electrodes are normally made into diamond pattern with ITO and with metal bridge.
Human body is conductive because it contains water. Projected capacitive technology makes use of conductivity of human body. When a bare finger touches the sensor with the pattern of X and Y electrodes, a capacitance coupling happens between the human finger and the electrodes which makes change of the electrostatic capacitance between the X and Y electrodes. The touchscreen controller detects the electrostatic field change and the location.
Projected capacitive supports multiple touches (Multi-touch), so it supports a lot of gestures: Zoom in and out (pinch/spread), scroll, swipe, drag, slide, hold/press, rotate, tap etc.
With the new development, projected capacitive touch panels can support gloved hand touch with different glove materials and touch with water or even with salt water.
With the fast development of projected capacitive, resistive touchscreen devices market is shrinking rapidly but it is still widely used in some industrial applications because of the following advantages.
The following table shows the comparison of resistive and capacitive touch screens. It is up to your application to select the types of technology to use.
Touch panels have been a much better human machine interface which become widely popular. Orient Display has been investing heavy for capacitive touch screen sensor manufacturing capacity and LCD module production ability. With Orient huge production capacity, top notch quality, and competitive pricing, Orient has been working with top LCD panel manufacturers ,AUO, BOE, LG, Innolux and top touch controller manufacturers , Atmel (Microchip, Cypress, Synaptics, Elan, NXP, Goodix, Sharp, Hydis etc. to provide the best touch display technology in the market, such as IPS, MVA, in-cell, on-cell, automotive grade etc.
Orient Display developed a special smoke film which is very low cost but gives the customer a optical bonding performance. Smoke film uses optical interference to reduce the glass-air interface reflection for air (perimeter) bonding between LCD and touch screen.
TFT Display modules with Capacitive Touch Screen are more user-friendly and have better performance compared with the ones with Resistive Touch Screen. There are many combinations of TFT display modules with projected capacitive touchscreen (PCAP) for you to choose from. We offer modules with various features including modules with control board, wide viewing angle, sunlight readable, wide temperature, and Monochrome. The available sizes are 0.96", 3.5", 3.9", 4.3", 5", 5.2" 5.7", 7" and 10.1"
Alibaba.com offers 7522 7 inch tft capacitive touch screen products. About 15% % of these are lcd modules, 10%% are touch screen monitors, and 10%% are lcd touch screen.
A wide variety of 7 inch tft capacitive touch screen options are available to you, You can also choose from original manufacturer, odm and agency 7 inch tft capacitive touch screen,As well as from tft, ips, and standard.
A capacitive touchscreen consists of a display and a touch panel. A control is usually already integrated. Some call the capacitive touch panel display screen only the touch panel. In any case, however, it is about the possibility of making entries on a larger area in order to read outputs at the same time or to display keypads and input or output. hide. Vandal-proof glass panes are required for POI stations, in industry and medical technology it is necessary that the touch screen can also be operated with gloves (resistive touch panel).
Typical representatives of capacitive touch screens are the EA eDIPTFT display and the EA uniTFT capacitive touch display (linked here). You can buy these touchscreens in different sizes and designs.
