Page 25: Basic Operation Of Tft-Lcd
Basic operation of TFT-LCD 1. After turning on power switch, PSU board sends 5Vst-by Volt to Main IC MT5371 waiting for ON signals from Key Switch or Remote Receiver. 2. When the ON signal from Key Switch or Remote Receiver is detected, MT5371 will send ON Control signals to Power.

Page 102 3. Electrical Specification The T315XW02 V7 requires two power inputs. One is employed to power the LCD electronics and to drive the TFT array and liquid crystal. The second input power for the BLU, is to power inverter.. 3-1 Electrical Characteristics Parameter Values Unit...
Page 103 3. Measurement condition : Trush = 470 uS 4. VCIM = 1.2V VCIM 5. The performance of the Lamp in LCM, for example life time or brightness, is extremely influenced by the characteristics of the DC-AC Inverter. So all the parameters of an inverter should be carefully designed so as not to produce too much leakage current from high-voltage output of the inverter.

Page 112 4. Optical Specification Optical characteristics are determined after the unit has been ‘ON’ and stable for approximately 45 ℃ minutes in a dark environment at 25 . The values specified are at an approximate distance 50cm from the LCD surface at a viewing angle of Φ and θequal to 0°. Fig.1 1 presents additional information concerning the measurement equipment and method.
Page 113 Note: 1. Contrast Ratio (CR) is defined mathematically as: Surface Luminance of Contrast Ratio= Surface Luminance of off1 2. Surface luminance is luminance value at point 1 across the LCD surface 50cm from the surface with all pixels displaying white. From more information see FIG 2. When VDDB = 17.5V, IDDB = TBD L =Lon1 ,Where Lon1 is the luminance with all pixels displaying white at center 1 location.
Page 114 FIG.3 Response Time The response time is defined as the following figure and shall be measured by switching the input signal for “any level of gray(bright) “ and “any level of gray(dark)”. Any level of gray(Bright) Any level of gray(Dark) Any level of gray(Bright) L0,15,L31,….L255 L0,15,L31,….L255...

Page 123 9. PRECAUTIONS Please pay attention to the followings when you use this TFT LCD module. 9-1 MOUNTING PRECAUTIONS (1) You must mount a module using holes arranged in four corners or four sides. (2) You should consider the mounting structure so that uneven force (ex. Twisted stress) is not applied to module.
Page 124 9-3 ELECTROSTATIC DISCHARGE CONTROL Since a module is composed of electronic circuits, it is not strong to electrostatic discharge. Make certain that treatment persons are connected to ground through wrist band etc. And don ’t touch interface pin directly. 9-4 PRECAUTIONS FOR STRONG LIGHT EXPOSURE Strong light exposure causes degradation of polarizer and color filter.
