1. General Description
The LD470DXS is a Color Active Matrix Liquid Crystal Display with an integral Light Emitting Diode (LED) b a c k l i g ht s ys tem . T he m atr ix em p lo ys a- S i T hin F i lm T r ans is to r as the ac t i ve e lem ent. It is a transmissive display type which is operating in the normally black mode. It has a 46.97 inch diagonally measured active display area with WXGA resolution (768 vertical by 1366 horizontal pixel array). Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arranged in vertical stripes. Gray scale or the luminance of the sub-pixel color is determined with a 8-bit gray scale signal for each dot, thus presenting a palette of more than 16.7M(true) colors. It has been designed to apply the 8-bit 1-port LVDS interface. It is intended to support Public Display where high brightness, super wide viewing angle, high color gamut, high color depth and fast response time are important. EEPROM

Notes : 1. Electrical characteristics are determined after the unit has been ‘ON’ and stable for approximately 60 minutes at 25±2°C. The specified current and power consumption are under the typical supply Input voltage 24Vand VBR (Ext VBR-B : 100%), it is total power consumption. 2. The life time (MTTF) is determined as the time which luminance of the LED is 50% compared to that of initial value at the typical LED current (ExtVBR-B :100%) on condition of continuous operating in LCM state at 25±2°C 3. LGD recommend that the PWM freq. is synchronized with One time harmonic of Vsync signal of system. Though PWM frequency is over 120Hz (max 252Hz), function of LED Driver is not affected. 4. The duration of rush current is about 200ms. This duration is applied to LED on time. 5. Even though inrush current is over the specified value, there is no problem if I2T spec of fuse is satisfied. 6. Ext_PWM Signal have to input available duty range. Between 99% and 100% ExtVBR-B duty have to be avoided. ( 99% < ExtVBR-B < 100%) But ExtVBR-B 0% and 100% are available.

Notes : 1. Contrast Ratio (CR) is defined mathematically as : Surface Luminance at all white pixels CR = Surface Luminance at all black pixels It is measured at center 1-point. 2. Surface luminance is determined after the unit has been ‘ON’ and 1Hour after lighting the backlight in a dark environment at 25±2°C. Surface luminance is the luminance value at center 1-point across the LCD surface 50cm from the surface with all pixels displaying white. For more information see the FIG. 2. 3. The variation in surface luminance , δ WHITE is defined as : δ WHITE(5P) = Maximum(Lon1,Lon2, Lon3, Lon4, Lon5) / Minimum(Lon1,Lon2, Lon3, Lon4, Lon5) Where Lon1 to Lon5 are the luminance with all pixels displaying white at 5 locations . For more information, see the FIG. 2. 4. Response time is the time required for the display to transit from any gray to white (Rise Time, TrR) and from any gray to black (Decay time, TrD). For additional information see the FIG. 3. ※ G to G Spec stands for average value of all measured points. Photo Detector : RD-80S / Field : 2 ° 5. Viewing angle is the angle at which the contrast ratio is greater than 10. The angles are determined for the horizontal or x axis and the vertical or y axis with respect to the z axis which is normal to the LCD module surface. For more information, see the FIG. 4. 6. Gray scale specification Gamma Value is approximately 2.2. For more information, see the Table 11. Table 11. GRAY SCALE SPECIFICATION
