OLED Module technology and development with echoes, OLED drive also plays an increasingly important role. Not only from the low duty cycle increases to support high duty cycle, and the application of such a control current for each RGB, wider IC operating temperature (-45 to 80 ℃), the internal DC-DC boost, as well as graphics acceleration instruction and some other features.

Optical Design Character LCD Modules
Geometry of the light guide plate and the luminance distribution is determined by the liquid crystal display manufacturers to design the light distribution of the light guide plate is usually utilized raytrace light guide plate, the shape of the light guide plate speculation intensity of light emitted. Total reflection within the light guide plate caused by a guide, so the light emitted from the light guide and can not fully satisfy this condition. For example, a flat plate-shaped light guide, for example, if the light is in full compliance with the conditions for total reflection critical angle of the emitted light does not exist, similar to the light guide plate of this type must be in the bottom of it and the front set MR device. 256x64 oled
The design surface of the backlight unit of the light intensity distribution, it is necessary for the MR, or MD optical design and simulation. Required when the optical design of the cold cathode fluorescent lamp into a diameter, length and shape of the lamp the parabolic reflection film and other parameters (parameter), with these parameters can assume that the surface of the backlight unit presumed light intensity distribution. They can also take advantage of LIGHT TOOL's backlight unit using optical design software, the estimated value for the light intensity distribution determines the location of MR or MD. 16x4 lcd display
