Grayscale panel case is still in the chase oled module

Therefore decided to display the product's performance capabilities, and ultimately decided on the performance of the panel itself. Because no matter how good the display, showing how the internal use of high-end products arithmetic processor, when the display richer grayscale image, if the panel itself does not have a high degree grayscale display capability, so good display, high computing processors are no longer meaningful sex. If you look for panel multi-grayscale of study will find that it shows in terms of capacity, the 256x64 oled there is a considerable degree of room for improvement, because including plasma panel, DMD display components, etc., as opposed to the LCD panel, in the performance technical capabilities have been considerable lead, and the panel is still in catch-up situation.
Because of the panel will be different, gray scale display capabilities are different, which is the gray scale of the control principle is completely different reasons. The liquid crystal panel is a liquid crystal molecule alignment according to the different angle, the light flux from the control worn through. That is, the panel is a liquid crystal alignment according to the angle to determine the brightness of the display, and wish to improve the control of the alignment angle of the liquid crystal is very difficult. And the corresponding response, plasma panel, DMD display components, etc., is itself only shows 0 (black) or 1 (white) two brightness values. So you can take a picture of change during the (usually around 16.7ms) emitting pulses to control the brightness, which is the so-called "pulse amplitude" approach. Simple terms, just need to increase the luminous detail can be separated grayscale performance ability, therefore, compared with LCD panels, plasma panels, DMD and other grayscale performance capabilities for superior LCD panel also compared.
And on the circuit part of the explanation is that the 128x32 oled grayscale display capability is responsible for controlling the alignment of liquid crystal molecules Source Driver IC, their analytical ability to determine the output voltage, that panels can increase the number of gray scale capability, is determined by the driver IC. Now on the market, the mainstream driver IC with 6 ~ 8 bit resolution capability, mostly multi-panel TVs are using 8bit driver IC, but I believe in the years after 2006, 10 bit driver IC will gradually be applied to the liquid crystal TV panel.
