Produce full-color Character LCD Modules device program adopted

Produce full-color OLED device, you can use the following scenarios:
1. RGB mode superposition device
This mode is not the way to achieve color display light color conversion or color filter, thus increasing the luminous efficiency.Character LCD Modules  This superposition model requires material better performance and better driving characteristics, process conditions demanding.
2. Blue light emitting device + color conversion layer mode
This model was first developed by Japan's Idemitsu success, there is a blue light-emitting organic electroluminescent devices is the highest energy, so let through light color conversion medium blue, green and red excitation. The blue organic electroluminescent device structure of anode / hole injection layer / hole transport layer /
Emitting layer / electron transport layer / cathode, wherein the emitting layer is a blue electroluminescent DSA materials. Luminous efficiency of 61m / W, life of 20,000 hours, on the basis of light-emitting color conversion medium to produce a multicolor pattern organic electroluminescent device. This process requires efficient blue hair
Optical layer.
3. White device + color filter pattern
This technology was first launched in Japan TDK Corporation, the white light emitted by the device to obtain a color filter color. High cost of the color filter, the light emitting efficiency is not high, although this pattern can obtain high color purity, red, green and blue light emitting device trichrome different aging characteristics,color lcd display module the color purity will change over time.
Encapsulated OLED device performance characterization tests must be carried out, mainly brightness - voltage curve and the current density - voltage curve. The steeper the curve rises, the brightness with voltage, current density with the faster voltage rise, the luminous efficiency will be higher.
