11 / 23 page LD15756B- 8 6. Electrical Characteristics 6-1. TFT-LCD panel driving Ta=25℃ Parameter Symbol Min. Typ. Max. Unit Remark Vcc Supply voltage Vcc +4.5 +5.0 +5.5 V 【Note2】 Current dissipation Icc − T.B.D T.B.D mA 【Note3】 Permissive input ripple voltage VRF − − 100 mVp-p Vcc=+3.3V Differential input High VTH − − +100 mV VCM=+1.2V threshold voltage Low VTL –100 − − mV 【Note1】 Terminal resistor RT − 100 − Ω Differential input 【Note1】 V CM : Common mode voltage of LVDS driver. 【Note2】 1)On-off sequences of Vcc and data 0<t1≦10ms 0<t2≦10ms 0<t3≦1s 1s≦t4 200ms≦t5 Power sequence for Backlight is not especially specified, however it is recommended to consider some timing difference between LVDS input and Backlight input as shown above. If the Backlight lights on before LCD starting, or if the Backlight is kept on after LCD stopping, the screen may look white for a moment or abnormal image may be displayed. This is caused by variation in output signal from timing generator at LVDS input on or off. It does not cause the damage to the LCD module. 2)Dip conditions for supply voltage 1) V2 ≦Vcc< V1 td≦ 10ms 2) Vcc<V2 Vcc-dip conditions should also follow the on-off conditions. 【Note3】 Typical current situation : 16-gray-bar pattern Vcc=+5.0V, CK=54MHz Horizontal period =15.7 us Gray scale : GS(4n) n=0∼15 The explanation of each gray scale, GS(4n), is described below section 8-2. 0.9Vcc Back light data Vcc t3 t4 t1 t5 0.1Vcc 0.1Vcc 0.9Vcc 0.1Vcc t2 OFF ON OFF Vcc td V2 V1 V1 : 4.5V V2 : 3.6V RGB GS0 RGB GS4 RGB GS8 RGB GS56 RGB GS60 .... |
