The L D1041 products are a family of high bright LCD monitors intended for use in a variety ofindustrial and commercial applications. Some of these applications include Car TV, Kiosk, Control Panel,Fish Finder, Marine, POI, Teketing, Aviation, Advertising, Gas Pumps, Signage... The LCD panel forL D1041 has a particularly fast response time of 35ms and consequently very well suited for video applications.The L D1041 is a 10.4” active matrix TFT LCD with a native resolution of 800X600 (SVGA). It has a typical luminance of 1500 nits with a +12VDC input. The video interface is through a standard 15 pin analog input with an integrated On-Screen Display (OSD).OUTLINESTRUCTURE AND PRINCIPLEL D1041 module is composed of the driver LSIs for driving the TFT (Thin Film Transistor) array with anamorphous silicon thin film transistor liquid crystal display (a-Si TFT LCD) panel structure and a backlight.The a-Si TFT LCD panel structure is injected liquid crystal material into the narrow gap between a TFT array glass substrate and a color filter glass substrate.RGB (Red, Green, and Blue) data signals from a source system are modulated into a form suitable for active matrix addressing by the onboard signal processor and sent to the driver LSIs which in turn address theindividual TFT cells.Working as an electro-optical switch, each TFT cell regulates transmitted light from the backlight assembly when worked by the data source. Color images are created by regulating the amount of transmitted light through the array of red, green and blue dots.APPLICATIONSE Car TV, Kiosk, Control Panel, Fish Finder, Marine, POI, Teketing, Aviation, Advertising, Gas Pumps, Signage...

When you are designingthe inverter, the output voltage of the inverter should comply with the following conditions.(1) The area under the positive and negative cycles of the waveform of the lampcurrent and lamp voltage should be area symmetric (the symmetric ratio should be larger than 90%).(2) There should not be any spikes in the waveform. (3) The waveform should be sine wave as possible.(4) Lamp current should not exceed the maximum value within the operatingTemperature (It is prohibited to over the maximum lamp current even if operated in The non-guaranteed temperature). When lamp current over the maximum value for a long time, it may cause fire. Therefore, it is recommend that the inverter should have the current limited circuit.Note 3: Lamp frequency may produce interference with horizontal synchronous frequencyand this may cause line flow on the display. Therefore lamp frequency shall be detached from the horizontal synchronous frequency and its harmonics as far as possible in order to avoid interference.Note 4: Brightness (I L =6mA/Lamp) to be decrease to the 50% of the initial value.Note 5:CN2~4 connector (backlight): JST BHR-03VS-1Pin no.
