Interface Timing Mode The 8080 mode MCU interface consist of CS#, D/C#, RD#, WR#, D[15:0] and TE signals. This interface use WR# to define a write cycle and RD# for read cycle. If the WR# goes low when the CS# signal is low, the data or command will be latched into the system at the rising edge of WR#. Similarly, the read cycle will start when RD# goes low and end at the rising edge of RD#. Revision: 13-Dec-13 6 Document Number: 37489

Rise time, Tr, is the time between photo detector output intensity changed from 90%to 10%. And fall time, Tf, is the time between photo detector output intensity changed from 10%to 90% Display Data 100% 90% W hite(tft OFF) Black(TFT ON) W hite(tft OFF) 10% 0% Note 4: Definition of contrast ratio: The contrast ratio is defined as the following expression. Contrast ratio (CR) = Luminance measured when LCD on the "White" state Luminance measured when LCD on the "Black" state Note 5: White Vi = Vi50 ± 1.5V Black Vi = Vi50 ± 2.0V ± means that the analog input signal swings in phase with VCOM signal. ± means that the analog input signal swings out of phase with VCOM signal. The 100% transmission is defined as the transmission of LCD panel when all the input terminals of module are electrically opened. Note 6: Definition of color chromaticity (CIE 1931) Color coordinates measured at the center point of LCD Note 7: Measured at the center area of the panel when all the input terminals of LCD panel are electrically opened.
