1.78 inch AMOLED is a low power consumption AMOLED with 368x448 resolution and mipi/spi interface.
The IC mode is RM69090 which is widely used in wearable AMOLED displays such as 1.39" AMOLED.
It has a integrated CTP with TMA525C touch IC.
Application: Wearable, Medical equipment
Compare to LCD, OLED has many advantages as follows:
Thin Like Paper:More than 50% thinner and lighter than LCD, creating an edgy form factor in style.
Green Power:Clock-mode standby can be up to 60 hours, much lower consumption compare to LCD displays.
"Wow" Effect:High contrast ratio and wide color gamut offer sharp and vivid image, and consistent display from any angle.
OLED driver as well as two divided into passive (PMOLED) active (AMOLED), which PMOLED simple structure, each pixel is represented by a separate cathode and anode control, no additional driver circuit, but too much control lines restrict its application of high-resolution large screen; AMOLED entire cathode surface electrode via a drive circuit driving the light emitting anode, significantly reducing the number of control lines, it has a low-power, high-resolution, fast response and other characteristics, AMOLED therefore gradually become the mainstream OLED display.
For high-resolution AMOLED, the size of the driving circuit smaller and smaller, but the electrical performance requirements have become more sophisticated, conventional Si (Amorphous Silicon, A-Si) technology has been difficult to meet the requirements, and low-temperature polysilicon (low Temperature Poly Silicon, LTPS) a technical solution to this problem, the core is by an excimer laser annealing the amorphous silicon into polysilicon, has higher carrier mobility, lower defect density, the device in a small size can still have better electrical properties.
