(six bits each for red, green, and blue) as is common for AMLCD displays. Because the EL320.240-FA3 requires just 4 bits (two each for red and green), the 18 bits would need to be mapped into 4 bits. -
Page 7: Display Overlay Considerations
SGD data into the color data required by the EL320.240-FA3. SGD data is one bit per pixel, and 4 pixels of data are latched per video clock edge. The EL320.240-FA3 is 4 bits per pixel with one pixel of data latched per clock edge. Display Overlay Considerations Though not a requirement, often the end system will employ some type of transparent cover over the front the display. -

Page 20: Dimming
Dimming is used to reduce the display luminance to better match ambient conditions or to reduce power consumption. There are two methods for dimming the EL320.240-FA3 display. The preferred method is digital dimming, where the internal display frame rate is controlled using the LUM0 and LUM1 inputs. The internal frame rate is the frequency at which the drive voltage is applied to the display phosphor and thus impacts luminance and power consumption. -
