What is the difference between uled and oled?

The difference between ULED and organic light emitting diode is that:

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.

Comparative evaluation of image quality between ULED and organic light-emitting diodes

China electronic chamber of commerce organized experts and consumers in the industry to make subjective evaluation on the image quality of Hisense ULED and OLED. The evaluators are the Third Research Institute of China Electronics Technology Group, Beijing Film Academy, Tsinghua University Academy of Fine Arts and National Radio and Television Product Quality Supervision and Inspection Center.

Seven experts and eight ordinary consumers from Tsinghua University Department of Electronic Engineering, Certification Center of China Institute of Electronic Technology Standardization and China Photographers Association conducted a blind test in four groups.

This comparative test of subjective evaluation is conducted according to GB/T 22 123-2008 Subjective Evaluation Method for Images and Sounds of Digital TV Receiving Equipment, and the image quality of Hisense ULED and the comparative prototype OLED TV is compared and evaluated by stimulus comparison method. After testing, ULED scored more than organic light-emitting diodes in eight key image quality indicators, especially in moving picture performance, clarity and color.
