The difference between Oled TV and LED TV The difference between Oled TV and uled TV

Oled TV adopts new technology, which is not well understood by everyone. It is often compared with LED TV and uled TV. Next, Bian Xiao will answer the difference between them.

First, the difference between Oled TV and led TV

1, different light sources.

Each pixel of OLED TV screen panel can emit light independently without backlight. LED TV itself does not emit light, but uses LED as the backlight of the display.

2. The generated wave band has different harm to eyes.

However, due to the self-luminous characteristics of OLED TV, the blue light band produced is mainly concentrated at 460nm, which is not harmful blue light, with low energy and little harm to human eyes. In the light of traditional LED TV, blue light is everywhere. Blue light with relatively high energy in 400nm-480nm band is harmful to human eyes, and long-term exposure to blue light radiation will induce eye diseases.

3. Different color accuracy and contrast.

Each pixel of OLED TV can emit light independently, and the light source can be controlled spontaneously, which can directly control the brightness change of pixels, thus bringing true black. Black is purer, has a wider color gamut, is unlikely to leak light, and improves contrast and image quality. However, the expressive force of LED TV in high-speed dynamic pictures is obviously insufficient, and the phenomenon of afterimage cannot be eradicated.

Second, the difference between OLED TV and uled TV

1, the luminescence principle is different

ULED needs to emit light through backlight, and liquid crystal molecules themselves cannot emit light. LED refers to backlight. Organic light-emitting diodes are organic light-emitting diodes, which can emit light by themselves without backlight.

2. Technical differences

Organic light emitting diode is the next generation display technology, and ULED is just an optimization technology. These two technologies are not at the same level.

3. Differences in screen display

Compared with OLED TV, ULED based on liquid crystal principle provides 4 times better white field and 2 times better contrast, and at the same time provides 2 times brighter visual range with higher picture details.

The difference between Oled TV and led TV and uled TV is as above. I hope I can help you.
