General DescriptionThe LC370EUN is a Color Active Matrix Liquid Crystal Display with an integral Light Emitting Diode (LED) b a c k l i g h t s ys t e m . T h e m a t r i x e m plo ys a- S i T h in 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 37 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 16.7 Million colors. It has 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.Mini-LVDS(RGB) LVDS EEPROM SCL LVDS 1,2 Option signal SDAG1Source Driver CircuitS1 S19202PortLVDS Select OPC EnableTiming ControllerLVDS Rx + OPC + DGA Integrated Control SignalsG1080TFT - LCD Panel(1920 × RGB × 1080 pixels) [Gate In Panel]CN1(51pin)ExtVBR-B +12.0VI2CPower Circuit BlockPWM_OUT CN2 1~3 (8 pin) PWM_OUT 1~3Power SignalsScanning Block 1 Scanning Block 2LED Driver+24.0V, GND, On/OffScanning Block 3General FeaturesActive Screen Size Outline Dimension Pixel Pitch Pixel Format Color Depth Luminance, White Viewing Angle (CR>10) Power Consumption Weight Display Mode Surface Treatment 37 inches(940.091mm) diagonal 856.4(H) × 501.0(V) X 10.8(B)/23.6 mm(D) (Typ.) 0.42675 mm x 0.42675 mm 1920 horiz. by 1080 vert.

Surface luminance are determined after the unit has been ‘ON’ and 1 Hour 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).

PrecautionsPlease pay attention to the followings when you use this TFT LCD module.9-1. Mounting Precautions(1) You must mount a module using specified mounting holes (Details refer to the drawings).(2) You should consider the mounting structure so that uneven force (ex. Twisted stress) is not applied to themodule. And the case on which a module is mounted should have sufficient strength so that external force is not transmitted directly to the module.(3) Please attach the surface transparent protective plate to the surface in order to protect the polarizer.Transparent protective plate should have sufficient strength in order to the resist external force.(4) You should adopt radiation structure to satisfy the temperature specification.(5) Acetic acid type and chlorine type materials for the cover case are not desirable because the formergenerates corrosive gas of attacking the polarizer at high temperature and the latter causes circuit break by electro-chemical reaction.(6) Do not touch, push or rub the exposed polarizers with glass,tweezers or anything harder than HBpencil lead. And please do not rub with dust clothes with chemical treatment.Do not touch the surface of polarizer for bare hand or greasy cloth.(Some cosmetics are detrimental to the polarizer.)(7) When the surface becomes dusty, please wipe gently with absorbent cotton or other soft materials likechamois soaks with petroleum benzine. Normal-hexane is recommended for cleaning the adhesives used to attach front / rear polarizers. Do not use acetone, toluene and alcohol because they cause chemical damage to the polarizer(8) Wipe off saliva or water drops as soon as possible. Their long time contact with polarizer causesdeformations and color fading.(9) Do not open the case because inside circuits do not have sufficient strength.9-2. Operating Precautions(1) The spike noise causes the mis-operation of circuits. It should be lower than following voltage:V=±200mV(Over and under shoot voltage)(2) Response time depends on the temperature.(In lower temperature, it becomes longer.)(3) Brightness depends on the temperature. (In lower temperature, it becomes lower.)And in lower temperature, response time(required time that brightness is stable after turned on) becomes longer(4) Be careful for condensation at sudden temperature change.Condensation makes damage to polarizer orelectrical contacted parts. And after fading condensation, smear or spot will occur.(5) When fixed patterns are displayed for a long time, remnant image is likely to occur.(6) Module has high frequency circuits. Sufficient suppression to the electromagnetic interference shall bedone by system manufacturers. Grounding and shielding methods may be important to minimized the interference.(7) Please do not give any mechanical and/or acoustical impact to LCM. Otherwise, LCM can’t be operatedits full characteristics perfectly.(8) A screw which is fastened up the steels should be a machine screw.(if not, it can causes conductive particles and deal LCM a fatal blow)(9)Please do not set LCD on its edge.(10) The conductive material and signal cables are kept away from LED driver inductor to prevent abnormaldisplay, sound noise and temperature rising.。
