Unit TRW Reset pulse duration TRT Reset cancel 10 - 5(Note 1,5) 120(Note 1,6,7) µs ms ms Note: 1. The reset cancel includes also required time for loading ID bytes, VCOM setting and other settings from NVM (or similar device) to registers. This loading is done every time when there is HW reset cancel time (tRT) within 5 ms after a rising edge of RESX. 2. Spike due to an electrostatic discharge on RESX line does not cause irregular system reset according to the table below: RESX Pulse Action Shorter than 5µs Longer than 9µs Between 5µs and 9 µs Reset Rejected Reset Reset starts 3. Suring the Resetting period, the display will be blanked (The display is entering blanking sequence, which maximum time is 120 ms, when Reset Starts is Sleep Out-mode. The display remains the blank state in Sleep In-mode.) and then return to Default condition for Hardware Reset. 4. Spike Rejection also applies during a valid reset pulse as shown below: 5. When Reset is applied during Sleep In Mode. 6. When Reset applied during Sleep Out Model. 7. It’s necessary to wait 5msec after releasing RESX before sending commands. Also Sleep Out command cannot be sent for 120 ms. FORM DT-030 Iss 3 Product Specification | Product No: DMT024QVNUCMI-2A REV. A ©2018 Densitron Technologies Limited. All rights reserved.

To stabilise the luminance, measurements should be executed after lighting the backlight for 30 minutes in a windless room. 1 Setup Measure output signal waveform by the luminance meter when raster of window pattern is changed from white to black and from black to white. 2 Response time Measure maximum brightness and minimum brightness at the centre of the screen by displaying raster or window pattern. Then calculate the ratio between these two values. 3 Contrast ratio Brightness of unselected position (white) Contrast Ratio (CR) = Brightness of selected position (black) Move the luminance meter from right to left and up and down and determinate the angles where contrast ratio is 10 4 Viewing angle Horizontal θ Vertical Ø 5 Colour chromaticity 6 Brightness distribution Measure chromaticity coordinates x and y of CIE1931 colorimetric system (Brightness distribution) = 100 x B/A % A: max. brightness of the 9 points B: min. brightness of the 9 points FORM DT-030 Iss 3 Product Specification | Product No: DMT024QVNUCMI-2A REV.
