+
|
|
|
+Note:
|
|
|
+ 3.Viewing angle is the angle at which the contrast ratio is greater than 10. The viewing
|
|
|
+ are determined for the horizontal or 3, 9 o’clock direction and the vertical or 6, 12
|
|
|
+ o’clock direction with respect to the optical axis which is normal to the LCD surface (see
|
|
|
+ FIG.2).
|
|
|
+ 4.Contrast measurements shall be made at viewing angle of Θ= 0and at the center of the
|
|
|
+ LCD surface. Luminance shall be measured with all pixels in the view field set first to
|
|
|
+ white, then to the dark (black) state. (See FIG.2) Luminance Contrast Ratio (CR) is defined
|
|
|
+ mathematically.

|
|
+ “data” input signal ON and OFF. The times needed for the luminance to change from 10% to
|
|
|
+ 90% is Tfand 90% to 10% isTr.

|
+6.Power ON/OFF Sequence
|
|
|
+
|
|
|
+ VDDI and VDD can be applied in any order.
|
|
|
+ VDD and VDDI can be power down in any order.
|
|
|
+ During power off, if LCD is in the Sleep Out mode, VDD and VDDI must be powered down minimum
|
|
|
+ 120msec
|
|
|
+ after RESX has been released.
|
|
|
+
|
|
|
+ 7 / 12
|
|
|
+ During power off, if LCD is in the Sleep In mode, VDDI or VDD can be powered down minimum
|
|
|
+ 0msec after
|
|
|
+ RESX has been released.
|
|
|
+ CSX can be applied at any timing or can be permanently grounded. RESX has priority over CSX.
|
|
|
+ Note 1: There will be no damage to the display module if the power sequences are not met.
|
|
|
+ Note 2: There will be no abnormal visible effects on the display panel during the Power On/Off
|
|
|
+ Sequences.
|
|
|
+ Note 3: There will be no abnormal visible effects on the display between end of Power On
|
|
|
+ Sequence and before receiving Sleep Out
|
|
|
+ command. Also between receiving Sleep In command and Power Off Sequence.
|
|
|
+ Note 4: If RESX line is not held stable by host during Power On Sequence as defined in the
|
|
|
+ sequence below, then it will be necessary to
|
|
|
+ apply a Hardware Reset (RESX) after Host Power On Sequence is complete to ensure correct
|
|
|
+ operation. Otherwise function is not
|
|
|
+ guaranteed.
|
|
|
+
|
|
|
+6.1The power on/off sequence is illustrated below
|
|
|
+
|
|
|
+ 8 / 12
|
|
|
+ 6.2 Uncontrolled Power Off
|
|
|
+
|
|
|
+ The uncontrolled power-off means a situation which removed a battery without the controlled
|
|
|
+ power off
|
|
|
+ sequence. It will neither damage the module or the host interface.
|
|
|
+ If uncontrolled power-off happened, the display will go blank and there will not any visible
|
|
|
+ effect on the
|
|
|
+ display (blank display) and remains blank until “Power On Sequence” powers it up.
