What is Pixel Memory?
Xiang Su Nei Cun Chu Dan Yuan translates into "memory in pixels" in Chinese. Pixel memory is a combination of matrix technology and a one-bit memory circuit embedded in every pixel of a TFT display. In particular, MIP LCDs offer fast response times for moving images and text scrolling. Compared to traditional graphic displays, MIP LCDs require less power during refresh, allowing longer battery life. In addition, MIP LCDs have excellent reflective display performance, without the need for backlight.
In the current MIP display technology, the in-pixel memory cell is composed of a CMOS circuit. However, a simpler version of the in-pixel memory cell can be made using a single type of MOS transistor. This allows for a relatively high yield and lower production cost. Moreover, the MIP pixel's low power consumption and small size make it a suitable candidate for battery-powered applications.
The MIP pixel's other major accomplishment is its low cost and wide development prospects. Its low power consumption allows for long battery life, which is especially appealing to mobile applications. In addition, it provides a higher resolution than E-Ink, which is popular in consumer electronics. In addition, its simple structure is conducive to mass production.
A typical pixel array includes an in-pixel memory cell, a liquid crystal display cell (LC) and a number of embedded driver circuits. The in-pixel memory cell can be constructed using a single type of MOS transistor, such as a CMOS LTPS process. In particular, the CMOS LTPS process is a low-cost alternative to conventional CMOS processes, which may be advantageous for mass production. The MIP pixel is also easy to manufacture.
The name "memory in pixels" might not be a household word, but in the Chinese language, the name means "memory in the pixel." It is also called "Xia Mian" in Chinese, which can be interpreted as "memory in a pixel." The MIP pixel can display black and white, which is an interesting feat in and of itself. There is also an economic tiling circuit, which can generate pixel generation rates of up to 25 Mhz per pixel. The aforementioned in-pixel memory cell can store a black and white voltage.
The aforementioned in-pixel memory cell may not be the smartest or the most efficient, but its a definite must-have in today's smart wearables market. Not only is it relatively inexpensive to manufacture, but its one-bit memory circuit also provides excellent image quality and low power consumption. In fact, the Kyocera Memory in Pixel display combines excellent image quality with an extremely low power LCD cell structure design. The corresponding display technology is a definite contender for future smart wear applications, and may prove to be an ideal candidate for battery powered applications.
The aforementioned in-pixel cell consists of a number of subroutines that may or may not be of use. The most interesting subroutine is the MIP's aforementioned economic tiling circuit, which generates pixel generation rates of up to 25 Mhz. The aforementioned MIP pixel also comes with a number of other interesting features, such as a data input circuit 310, a drive control circuit 340, and a second data latch circuit 330.
