1. General Description
www.DataSheet4U.com
The LC470WUL is a Color Active Matrix Liquid Crystal Display with an integral Light Emitting Diode(LED) backlight system. The matrix employs a-Si Thin Film Transistor as the active element. It is a transmissive display type which is operating in the normally black mode. It has a 46.96inch diagonally measured active display area with WUXGA resolution (1080 vertical by 1920 horizontal pixel array). Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arrayed in vertical stripes. Gray scale or the luminance of the sub-pixel color is determined with a 10-bit gray scale signal for each dot. Therefore, it can present a palette of more than 1.06B(FRC) colors. It has been designed to apply the 10-bit 4-port LVDS interface. It is intended to support LCD TV, PCTV where high brightness, super wide viewing angle, high color gamut, high color depth and fast response time are important.Mini-LVDS(RGB)

Notes : 1. Electrical characteristics are determined after the unit has been ON and stable for approximately 120 minutes at 252C. The specified current and power consumption are under the typical supply Input voltage 24Vand VBR (ExtVBR-B : 100%), it is total power consumption. The ripple voltage of the power supply input voltage is under 0.5 Vp-p. LGD recommend Input Voltage is 24.0V 5%. 2. Electrical characteristics are determined within 30 minutes at 252C. The specified currents are under the typical supply Input voltage 24V. 3. The life time 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 25C. 4. 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. 5. The duration of rush current is about 10ms. 6. Even though inrush current is over the specified value, there is no problem if I2T spec of fuse is satisfied.

4. Optical Specification
Optical characteristics are determined after the unit has been ON and stable in a dark environment at 252C. The values specified are at an approximate distance 50cm from the LCD surface at a viewing angle of and equal to 0 . FIG. 1 shows additional information concerning the measurement equipment and method. Optical Stage(x,y) LCD Module Pritchard 880 or equivalent

Product SpecificationNotes :1. Contrast Ratio(CR) is defined mathematically as : www.DataSheet4U.com CR(Contrast Ratio) = Maximum CRn (n=1, 2, 3, 4, 5) Surface Luminance at position n with all white pixels CRn = Surface Luminance at position n with all black pixels n = the Position number(1, 2, 3, 4, 5). For more information, see FIG 2. 2. Surface luminance is determined after the unit has been ON and 120min after lighting the backlight in a dark environment at 252C. 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 , WHITE is defined as : 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 G(N) to G(M) (Rise Time, TrR) and from G(M) to G(N) (Decay Time, TrD).
