General DescriptionThe LC420EUN 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 41.92 inch 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 8-bit gray scale signal for each dot.Therefore, it can present a palette of more than 16.7Milion colors. Ithas been designed to apply the 8-bit 2-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.LVDSEEPROMSCLLVDS 1,2Option signalSDAG1EPI(RGB)2PortLVDS SelectOPCEnableS1Source Driver CircuitS1920Timing ControllerLVDS Rx + OPC + DGAIntegratedControlSignalsG1080TFT -LCD Panel(1920 ×RGB ×1080 pixels)[Gate In Panel]CN1(51pin)ExtVBR-B+12.0VI2CPWM_OUTCN21~3(4 pin)PWM_OUT1~3+24.0V, GND, On/OffPower Circuit BlockPower SignalsScanning Block 1LED DriverScanning Block 2Scanning Block 3General FeaturesActive Screen SizeOutline DimensionPixel PitchPixel FormatColor DepthLuminance, WhiteViewing Angle (CR>10)Power ConsumptionWeightDisplay ModeSurface TreatmentVer. 0.141.92 inches(10.77m) diagonal958.0(H) ×559.1(V) X 9.9(B)/17.4 mm(D) (Typ.)0.4833 mm x 0.4833 mm1920 horiz. by 1080 vert.

The performance of the electro-optical characteristics may be influenced by variance of the verticalrefresh rate and the horizontal frequency3. Spread Spectrum Rate (SSR) for 50KHz ~ 100kHz Modulation Frequency(FMOD) is calculated by (7 –0.06*Fmod), where Modulation Frequency (FMOD) unit is KHz.

Please set proper Spread Spectrum Rate(SSR) and Modulation Frequency (FMOD) of TV system LVDS output. 2. Please check FOS after you set Spread Spectrum Rate(SSR) and Modulation Frequency(FMOD) to avoid abnormal display.
