Mobile Phone Sub Display 128x128 Color 160x100 Color Such resolution (128x128 or 160x100) provides more pixels than 96x64 in unit area, so you can reach the better display quality. Furthermore, such resolution (128x128 or 160x100) can be identical with the Main Display, so data can be shared with the Main display without further processing to reduce the loading of the MPU. See Large Picture We use the SPRD (Shared Pixels Rendering Display) technology to improve the display quality and efficiency. SPRD can reduce the required output numbers, and improves the display qualities of photographs. Except for the various applications above, ST7528 has other advantages... Minimize the external component. Accurate mass production uniformity. High real world ESD resist ability. No flicker problem in application. Provide partial display to minimize the power consumption...etc. Product Qulity Assurance
