LCD / OLED Comparative Analysis

【R&D Department of Blaze Display】Let's take a look at the long history of LCD display technology, LCD display is a multi-layer complex structure, LCD structure is placed in the two parallel glass substrates which are placed in the liquid crystal cell, the lower substrate glass set TFT (thin film transistor), the upper The color filter is arranged on the substrate glass to control the rotation direction of the liquid crystal molecules through the signals and voltage changes on the TFT so as to achieve the display purpose by controlling whether the polarized light of each pixel exits or not.

In accordance with the backlight light source, LCD display is divided into two kinds of CCFL (cold cathode fluorescent lamp) and LED (light emitting diode), many manufacturers advertise themselves as LED displays, led us generally believe that LCD and LED are two kinds of display is Wrong, completely misleading the vast number of manufacturers, both of which are only different from the backlight light source.

OLED panel and the LCD panel is very different, compared to the OLED panel structure will be more simple, OLED's full name for the organic light-emitting diode, that is, OLED panel of light-emitting materials for organic materials, compared to inorganic materials, organic Materials have a natural short board in terms of longevity. OLED display technology with self-luminous features, the use of very thin coatings of organic materials and glass substrates, when the current through these organic materials will light, and the OLED display screen viewing angle, and can save power. Because of its self-luminescent properties, OLEDs perform more purely in black because the materials are black as long as they do not emit light, while wide viewing angles, high contrast, low power consumption, and high reaction rates are all characteristics of the OLED panel. Currently there are RGB OLED and white OLED, RGBOLED mainly used in small screen, and white OLED mainly used in big screen TV and the like.
