10bit grayscale Character LCD Modules panel high above

In terms of the ability to display, 10bit driver IC seems to be required in the future to meet this regard, while the development of the next generation of driver IC can also come to an end. However, the fact is not the case, the driver IC industry is still actively preparing a new generation of technology, because Source driver IC output voltage resolution capability can be improved, then more than RGB color 10bit 20x2 oled panel, may also be made out, for example, from 2006 onwards, including Oki and NEC Electronics, they began selling 13bit and 12bit respectively the Source Driver IC samples. Some may be high above the 10bit gray scale capability to question the liquid crystal panel, the output voltage will be that even with the higher resolution capability of the driver IC, if the liquid crystal molecules with the deviation of each pixel, if more than the control precision of gray , then the end is still to no avail.
Therefore, compared with the reality, it seems that the Source 13bit and 12bit driver IC meaningfulness big, but this aspect of the product development industry does not think so, including Oki and NEC Electronics developed the Source 13bit and 12bit driver IC's intentions, not to achieve beyond 10bit grayscale display, but in order to make 10bit grayscale image displayed more clearly, that want to be able to pass higher resolving power of Source Driver IC for more precise control of RGB GAMMA features, and to up to compensate for backlight, color filter deviations caused by the object in RGB color registration errors. Because the panel is a backlight character oled display  the optical film, and so a combination of components, a component of any difference of the panel display capabilities are affected, resulting in varying degrees in RGB color registration error occurs, so that even with the 8bit Source Driver IC, for the panel, the panel does not necessarily guarantee equivalent to the output 8bit grayscale images.
