Advantages and disadvantages of LCD and OLED display

The advantages of liquid crystal are the disadvantages of organic light emitting diodes, and the disadvantages of liquid crystal are the advantages of organic light emitting diodes.

First the difference

The main difference between the two is the way the light is emitted,LCD is backlit panel light, while OLED materials can achieve self-illumination.

Advantages of OLED:

Display black: liquid crystal has a fatal defect, the liquid crystal layer can not be completely closed, liquid crystal display black, there will be some light through the color layer, so liquid crystal black is actually a mixture of black and white gray. OLED is truly black.

no light leakage :LCD has a backlight layer, the backlight of the LCD display is easy to leak from the gap between the screen and the border, which will lead to light leakage.

Light leakage is more obvious

Small thickness: OLED is thinner. Due to the presence of the backlight layer and the liquid crystal layer, the thickness of the liquid crystal display is much thicker than that of the OLED display

Flexibility: It is also because of the existence of the backlight layer and the liquid crystal layer, the lce screen can not be greatly bent, so most of the curved screens of mobile phones on the market are organic light-emitting diodes.

bright colors: OLED wins, you can see the contrast, the higher the contrast, the clearer the image, the more bright and colorful.

Individual highlights can be achieved: organic light-emitting diodes can make some areas glow independently. So you can have the lock screen and the ability to always tell the time.

Low power consumption: OLED is a pixel lamp, which does not work when working, while LCD is all working, so it is doomed to the power consumption of LCD.

Short screen response time: it takes time for a pixel to change from color 1 to color 2, which is called gray response time; This time is too long, will lead to visual residual image, affect the visual effect. Organic light-emitting diodes were almost without delay.

The disadvantages of OLED:

Fatal disadvantage: OLED is an organic material, and its life is much shorter than that of LCD inorganic materials. Four years is a luxury. (My iphone6s)

Burning screen: Pixels light up, causing the screen to age different pixels. However, as long as the brightness is below 60% and the phone does not show pictures for a long time, it can be guaranteed that the naked eye will be visible after three years.

2, the screen flicker: low brightness will have obvious stroboscopic, (light bulb flicker feeling), some people will have obvious discomfort, feel uncomfortable, dizziness. - It is very harmful to the eyes and is often criticized by the LCD party.

Low pixel density points: At the same resolution, OLED screens will have one-third the sharpness of a small square root.

The LCD is on the left and the organic light-emitting diode is on the right

LCD: RGB pixels are arranged, which can ensure the comprehensive development of sub-pixel information and display, and the imaging picture is natural.

Organic LED: Both pixels require the help of adjacent pixels to image, and there are colored jagged edges in the image.

The demand for the screen is actually to see the individual, if you need a brighter picture, faster response speed, thinner screen effect, only OLED,
