2. The visual angle is large, and the visual angle of the IPS hard screen panel can reach 178 degrees. The degree of color change between the front view and the different viewing angles is called color distortion, and the result shows that the numerical value obtained by the IPS hard screen can not be distinguished by naked eyes, namely the effect of viewing the picture from the front or the side is the same.
3. Professional colors and IPS hard screens can match the color matching capability of color experts, can truly present images, are widely applied to professional fields such as television stations and are well pursued by professionals.
4. The screen is firm, no ghost image and water mark exist during touch, the physical structure of the IPS hard screen is stable, and the unavoidable ghost image and flicker phenomenon on a common screen cannot occur during touch.
The capacitive touch screen has the following advantages:
1. capacitive touch screens only require touching, and do not require pressure to generate a signal.
2. Capacitive touch screens need only once or no calibration at all after production, while resistive technology requires conventional calibration.
3. The capacitive touch screen has long service life, and the components in the capacitive touch screen do not need to move. In a resistive touch screen, the upper ITO film needs to be thin enough to be flexible to bend down to touch the lower ITO film.
4. Capacitive touch screens are superior to resistive touch screens in both light loss and system power consumption.
5. The choice of capacitive or resistive technology depends primarily on the object touching the screen. Capacitive touch screens are a good choice if they are finger touches.
