What is the difference between Hisense ULED and OLED?

ULED and OLED differences are:

1, the principle of light-emitting different

ULED needs to be lighted by the backlight, liquid crystal molecules can not emit light themselves, LED refers to the backlight. And OLED is an organic light-emitting diode, can be self-emitting, so do not need a backlight.

2, technically different

OLED is the next generation of display technology, and ULED is just an optimization technology, these two technologies are not at a level.

3, the picture display on the different

Compared with OLED TV based on the principle of liquid crystal ULED provides four times better than its white field, two times the contrast, while providing two times the brightness of the visual range, the picture detail level is higher.

About ULED

ULED is a display image quality technology processing engine developed for e-medical displays and LCD televisions, using multi-zone independent backlight control and Hiview Picture Engine technology, which can be used to provide a more accurate reproduction and smoothness of the picture in terms of picture brightness, picture contrast, picture hierarchy, dark field details, color, and color. In terms of picture brightness, picture contrast, picture hierarchy, dark field details, color reproduction, picture smoothness and response speed, the picture quality performance has been greatly improved compared with traditional LED display, and its picture quality performance has comprehensively surpassed that of OLED in a number of subjective evaluation data.

ULED technology research and development in the initial stage of the National Development and Reform Commission project support, the project name of the liquid crystal display LED backlight and its key materials research and development and industrialization, also won the 2014 Ministry of Industry and Information Technology professional (medical) display module key technology research and development and industrialization of innovation and major special support.

ULED has obtained 13 invention patents, including the U.S. and European patent authorization, breaking the situation in which major display technology innovations were dominated by foreign companies.

ULED has developed to version 3.0 and realized 8K display with wider color gamut and higher contrast ratio than OLED.

On OLED

Organic Light-Emitting Diode (English: Organic Light-Emitting Diode, abbreviation: OLED), also known as Organic Electroluminescence Display (English: Organic Electroluminescence Display, abbreviation: OELD), organic light-emitting semiconductors. OLED technology was first researched by the French and Americans in the 1950s and 1960s, and then mass-produced by Sony, Samsung and LG in the 21st century.

and thin-film transistor liquid crystal displays for different types of products, the former has a self-luminous, wide viewing angle, high contrast, low power consumption, high response rate, full-color and process simplicity, etc., but the relative price of large panels, technology selectivity

, life, resolution, color reproduction can not be matched with the latter, organic light-emitting diode displays can be divided into monochrome, colorful and full-color and other types. Full-color and other types of full-color production technology is the most difficult, organic light-emitting diode displays can be divided into passive (Passive

Matrix, PMOLED) and active (Active Matrix, AMOLED) according to the different driving methods.
