OLED Technology

OLED display screen is a display screen made of organic spontaneous light diode control. It is considered to be a new application technology for the next generation of planar display because of the excellent characteristics of self-luminous organic excitation diode, no backlight, high contrast, thin thickness, wide angle of view, fast reaction speed, flexible panel, wide temperature range, simple construction and process.

Feature of OLED Technology


OLED is a self-luminous material, no need to use backlight board, at the same time wide angle of view, uniform quality, fast reaction speed, easy to color, with a simple drive circuit to achieve luminous, simple process, can be made into the flexible panel, in line with the principle of thin and short, the application range belongs to the small and medium-size panel.

Display: active luminescence, large range of viewing angle; fast response speed, stable image; high brightness, rich color, high resolution.

Working conditions: low driving voltage, low energy consumption, can be matched with solar cells, integrated circuits, etc.

Wide adaptability: large area flat panel display can be realized by using a glass substrate; if flexible material is used as a substrate, the foldable display can be made. since OLED is an all-solid-state, non-vacuum device, it has the characteristics of anti-seismic swing, low-temperature resistance (-40℃), and so on. It also has very important military applications, such as of modern weapons such as tanks and aircraft."

Type of OLED Technology


OLED is divided into active OLED (AM OLED) and passive OLED (PM OLED) according to driving mode)

PMOLED advantages and disadvantages

 Advantages: simple AM_OLED process and simple structure.

Disadvantages: large size is difficult. In order to maintain the brightness of the whole panel, it is necessary to improve the brightness of each Pixel and increase the operating current, which will reduce the OLED Device's life. Current Drive control is not easy.

AMOLED advantages and disadvantages

Advantages: large size, power saving, high resolution, long panel life, simple Data Driver design.

Disadvantages: complex process and high TFT variability."

Application of OLED Technology


Owing to the above advantages, in the commercial field OLED the display screen can be applied to POS and ATM machines, photocopiers, game consoles, etc.; in the communication field, it can be applied to mobile phones, mobile network terminals, etc.; in the computer field, it can be widely used in PDA、 commercial PC and household PC、 laptops; in the consumer electronics field, it can be applied to audio equipment, digital cameras, portable DVD; in industrial applications, instruments, etc.; in the transportation field, it can be used in GPS、 aircraft instruments, etc."
