1. หน้าจอ capacitive กับ resistive ต่างกันอย่างไร?
1. Cost: Capacitive screens are more expensive. Capacitive screens of different manufacturers are about 10 percent to 50 percent more expensive than resistive screens, while resistive screens are cheaper.
2. Power consumption: Industrial display capacitive screens consume more power than resistive screens.
3. Visual effects: The visual effects of capacitive screens and resistive screens are very good indoors, but the visual effects are obviously different outdoors, especially under sunlight. The capacitive screen works better, but the resistive screen reflects sunlight due to the extra screen layer, which makes the visual effect worse.
4. The feasibility of multi-touch: The multi-touch of the capacitive screen is achievable, depending on the method of implementation and the software used, and it has been implemented. The multi-touch of the resistive screen cannot be realized.
5. ความไวต่อการสัมผัส: หน้าจอ capacitive ใช้การตรวจจับปัจจุบันของร่างกายมนุษย์ในการทำงาน ดังนั้นวัสดุที่ไม่ใช่-วัสดุที่เป็นสื่อกระแสไฟฟ้า เช่น เล็บ ถุงมือ ฯลฯ จะไม่สามารถรับรู้ได้โดยระบบตรวจจับ capacitive ใต้หน้าจอ แต่เป็นตัวต้านทาน หน้าจอทำงานผ่านเซ็นเซอร์ความดัน สามารถสัมผัสกับวัตถุใดก็ได้ และรองรับสไตลัส
6. Damage resistance: The outermost layer of the capacitive screen is a protective layer of silica glass, which may be broken under severe impact. The outermost layer of the resistive screen is a thin film, which needs to be pressed down for pressure sensing, and the resistive screen supports a stylus, which makes the screen prone to scratches, requires a protective film and relatively more frequent calibration, but it is not easy than the capacitive screen break.
7. Cleanliness: Capacitive screens need to be touched with fingers, which are easy to leave stains on the screen, but because the outermost layer is a glass layer, it is easy to clean. The resistive screen supports operations such as stylus and nails, so it is not easy to stain the screen.
8. Accuracy: The capacitive screen can reach a few pixels in theory, but in fact, due to the limitation of the finger contact area, it is difficult for us to accurately click on targets less than 1cm. The accuracy of the resistive screen is at least as high as a single display pixel, which can be seen when using a stylus. It is convenient for handwriting recognition and helps to operate under the interface with small control elements.
9. Environmental adaptability: The operating temperature of the capacitive screen is between 0 degree and 35 degree , and a humidity of at least 5 percent is required. There is no specific value for the operating temperature of the resistive screen, but it has been confirmed that the resistive screen can work normally at a temperature of -15 degree to 45 degree , and the resistive screen has no requirements for humidity.
2. The following points are the selection methods, which can be selected according to their needs:
1. If the industrial display only uses basic functions, a resistive screen should be used, because the cost of the resistive screen is lower;
2, if the industrial display will often hit it during use, you should choose a resistive screen, because the capacitive screen is easily broken under impact;
3. หากอุณหภูมิในการทำงานของจอแสดงผลอุตสาหกรรมผันผวนอย่างมากและเกิน 00-350 คุณควรเลือกหน้าจอแบบต้านทานเนื่องจากอุณหภูมิในการทำงานของหน้าจอ capacitive คือ 00-350 และผลการทำงานของหน้าจอ capacitive ภายนอก พิสัยไม่ดีและอุณหภูมิในการทำงานของหน้าจอตัวต้านทาน พิสัยค่อนข้างกว้าง
4. If the industrial display needs to use the multi-touch function, you should choose the capacitive screen, because the resistive screen currently cannot support this function;
5. If the industrial display needs a longer standby time, you should choose a resistive screen, because the capacitive screen consumes more power than the resistive screen;
6. If the industrial display needs to use a stylus, you should choose a resistive screen, because the working principle of the capacitive screen causes the capacitive screen to not support the stylus;
7. If the working environment of the industrial display is relatively dry, you should choose a resistive screen, because the capacitive screen has humidity requirements for the working environment, but the resistive screen does not;
8. If the industrial display is often used in the sun, you should choose a capacitive screen, because the resistive screen reflects in the sun and affects its use;
