What is the difference between capacitive touch panel and resistive touch screen？
1. Touch Sensitivity
① Resistive touch screen: pressure is required to make the layers of the screen come into contact, and you can use fingers (even with gloves), nails, stylus, etc. to operate.
② Capacitive touch screen: The slightest touch from the surface of a charged finger can activate the capacitive sensing system below the screen. Inanimate objects, fingernails, gloves are invalid. Handwriting recognition is more difficult.
① Resistive touch screen: The accuracy is at least a single display pixel, which can be seen when using a stylus. Facilitates handwriting recognition and facilitates operations in interfaces that use small control elements.
② Capacitive touch screen: The theoretical accuracy can reach several pixels, but it is actually limited by the contact area of the finger. So that it is difficult for the user to precisely click on the target smaller than 1cm2.
3. Point-to-touch feasibility
① Resistive touch screen: The resistive screen only supports single-point touch, that is, it can only recognize and support the touch and click of one finger at a time. If more than two points are touched at the same time, it cannot respond correctly.
② Capacitive touch screen: The multi-touch technology supported by the capacitive screen can be greatly convenient to operate in actual use, and the sensitive sensitivity and damage resistance are more suitable for entertainment and games. For example, zooming in and out when browsing pictures, and zooming in and out of pages when browsing web pages, the user can also touch the screen with a single touch with both hands, or touch the screen with different gestures such as single-click, double-click, pan, press, scroll, and rotate to achieve arbitrary control, so as to Better and more comprehensive understanding of the relevant characteristics of the object (text, video, pictures, satellite films, 3D simulation, etc.)
4. Damage resistance
① Resistive screen: The fundamental characteristics of the resistive screen determine that its top is soft and needs to be able to be pressed down. This makes the screen very prone to scratches. Resistive screens require protective film and relatively more frequent calibration. On the plus side, resistive touch screen devices that use plastic layers are generally less prone to damage and are less prone to breakage.
② Capacitive screen: glass can be used for the outer layer. While not indestructible and likely to shatter under severe impact, the glass is better for everyday scratches and smudges.
① Resistive screen: Since it can be operated with a stylus or fingernail, it is more difficult to leave fingerprints, oil stains and bacteria on the screen.
② Capacitive screen: Touch with the whole finger, but the glass outer layer is easier to clean.
6. Visual effect in sunlight
①Resistive screen: The screen layer will reflect a lot of sunlight.
②Capacitive screen: still very good.
