Why don t IPS hard screen phones have high end products?

The disadvantage of the ISP screen is that it cannot be better packaged with COP, and it cannot use the function of in-screen fingerprint recognition. Since the display principle of the ISP screen is to illuminate the liquid crystal on the panel through the backlight, there is no way for the ISP screen to perform a better screen bending effect. In the past two years, mobile phone manufacturers have been trying to make higher "full-screen" mobile phones, and one of the main requirements to make this kind of mobile phone is to make the screen chin narrower.

In the process of ISP screen, the bottom of the panel contains many main control elements, so it is difficult to make the ISP screen narrow, which is not conducive to the trend development needs of mobile phones. <>

An important reason why many mobile phone manufacturers do not use ISP screens is that there is no way to carry out in-screen fingerprint recognition. Because now the under-screen fingerprint works by placing a CMOS sensor.

Place on the OLED screen.

Below, a fingerprint is captured using the space between the pixels of the OLED screen, pressed on the screen, and then the fingerprint is identified by comparing the images. However, the ISP screen must be backlit, so the panel is completely opaque, and of course the fingerprint cannot be recognized when taking pictures. Therefore, the mobile phones with ISP screens are basically rear-facing fingerprint recognition.

ISP screen compared with the OLED screen used by most mobile phone manufacturers now, OLED screen is thinner and lighter than ISP screen, zooming in to the entire mobile phone, every 1mm reduction in thickness means that the battery capacity can be reduced.

Zoom in to make your phone last longer. In addition, the OLED screen is also more energy-efficient than the chain ISP screen, and some flagship phones need to add NFC and wireless charging to the back cover.

Induction coil, so the range of battery capacity needs to be a little larger, so in order to save space, only OLED screens can be chosen. IPS screen.

One of the big drawbacks that is often overlooked is that at lower temperatures, the reaction of liquid crystal molecules slows down, resulting in a screen refresh rate.

Low, when using the phone outdoors in winter, you will also encounter the slow response of the phone screen. <>

The biggest disadvantage of the IPS screen is that it is high, followed by high energy consumption. Personally, I think it's not that mobile phone manufacturers don't want to use this screen, but that mobile phone manufacturers should think from the perspective of mobile phone consumers, since the business wants to make profits from consumers, it must be in the mobile phone hardware part of the war, and the IPS screen is expensive, and the performance is not the best, of course, it will be eliminated by the market.

The disadvantage of the IPS screen is that it is not very well packaged and does not have the function of screen fingerprint recognition, and now manufacturers are using thinner, lighter, and better quality OLED screens to replace the IPS screen.

The biggest disadvantage of this kind of screen is that the shadow is serious, so many manufacturers no longer use it.
