What is the difference between the N85 s OLED screen and the N96 s TFT screen Which is better

A thin film transistor is a liquid crystal display in which each pixel on the liquid crystal display is driven by a thin-film transistor integrated behind it. In this way, it can display screen information with high speed, high brightness and high contrast. TFT belongs to active matrix liquid crystal display.

It is also the screen commonly used in the current mid-to-high-end color screen mobile phones, divided into 65536 colors and 260,000 colors, 16 million colors, and its display effect is very good.

OLED is a new type of flat panel display technology, which has the characteristics of self-illumination, clear and bright, light and thin, fast response speed, wide viewing angle, low power consumption, and large operating temperature range, and has been recognized as the most ideal display technology. At present, it has gradually possessed the market of small-size displays such as mobile phones and automotive displays. In the future, large-size display markets, such as notebook computers and TVs, will become the target application areas of OLED.

The display of OLED can be divided into: monochrome, regional multicolor, and full color. In mobile phones, OLED is mostly used as a secondary screen, with a resolution of 96*64 area multi-color and full-color.

The following is a comparison of the performance of the two displays in the current mobile phone:

tft oled

Brightness 100cd m2 150cd m2

Power consumption 150MW 55-100MW

Contrast ratio 150:1 200:1

Operating temperature: 0, 50 degrees, -20 degrees, 75 degrees.

Viewing angle range 120 degrees 170 degrees.

The response time is 15ms

Thickness 4-5mm

Weight lightweight.

From the above data, you can basically know the performance of the two displays on the mobile phone.

So, if both are full-color displays, or both are regional multi-color displays, of course OLED is good.

If it is a regional multi-color display OLED and full-color TFT, there is no comparison in color performance, but in other performance, OLED is better than TFT.

Another point is that the cost of OLED is 40% lower than that of TFT after mass production.

Taking the resolution of 128*128,262K color inches as an example, PMOLED is about $1 cheaper than the cost of SITTFT-LCD.

The advantages of this display over traditional TFT products are: faster response, higher contrast, and wide viewing angles.

The Nokia N85's inch OLED display not only has a wide viewing angle, but also presents a picture with strong colors and warm tones, which is a stark contrast to other N-series models.

The benefits for the eyes are average.

What is OLED screen: OLED: Organic Light Emitting Display, that is, organic light-emitting display, belongs to the new rising category on mobile phone LCD, known as "dream display".

Unlike traditional LCD displays, OLED display technology does not require a backlight and uses a very thin coating of organic materials and a glass substrate that emits light when an electric current passes through it. Moreover, OLED display screens can be made lighter and thinner, with larger viewing angles, and can significantly save power.

OLED is a screen made of self-emitting diodes, a new technological material. Compared with TFT screens, the main advantages are power saving, bright colors, and large viewing angles. There is no argument for good or bad for the eyes!

It's just that the angle is larger and the color is more natural.

And then it's not good for your eyes.
