LC1200R, Very High Bright, 12. 1" Active Matrix Liquid Crystal Display (AMLCD) based product. It is intended for operation as a component in a high ambient light, outdoor system. The LC1200R has a scaleable video format capable of displaying a minimum of VGA (640 x 480) through XGA (1024 x 768) input resolution. [. . . ] The direction of the adjustment depends on the direction of the last adjustment. The direction will continue to be true until the maximum or minimum adjustment is reached. At this point, the direction will reverse LC1200R User's Guide 021-0183-00 Rev A 17 of 29 The Gain adjustment is to allow the full scale of the input video to be utilized. The direction of this adjustment will reverse when a limit is reached. For example, it will adjust from maximum to minimum, then reverse and go from minimum to maximum. The best way to make this adjustment is with a continuous gray scale pattern on the display. A proper adjustment will give continuous shading from black to white. Auto Adjust: All four parameters (clock, Horizontal position, Vertical position, and gain) can be adjusted automatically by pressing the Horz and DotClk+ button simultaneously. The LC1200R will sense the incoming video and optimize its settings. For best results, display a pattern containing white and black with some white pixels along all four edges while the auto adjust is performed. 6. 2 User Adjustments There are features that allow the user to adjust the properties of the LC1200R. These adjustments will require access to the video board PCB and the inverter. Access to the Photodiode Connector Section 2. 5. 3 and Dimming Control Connector Section 2. 5. 4 can be gained by removing 1 screw and a small access panel. ESD precautions should be taken when removing this panel or the back cover of the unit. Figure 6: Remove Screw and Door 6. 2. 1 Flip and Mirror The unit has the capability to flip and/or mirror the video image. This can be done to allow for the power and video connector to be located on the other side of the unit for flexibility in mounting the LC1200R. Jumpers are located on the LCD Video Controller Board. Rotating the display 180° will affect the apparent view angle. See Section 7 for view angle. LC1200R User's Guide 021-0183-00 Rev A 18 of 29 6. 2. 2 Max Bright Jumper The photodiode board can be removed from the system. When the photodiode board is unplugged the LC1200R will default to the minimum brightness mode. If the user would like to display to run at maximum brightness, the MAX BRIGHT, JP1, jumper must be inserted on the inverter board. See Figure 8 Figure 7 Install jumper to flip Install jumper to Mirror Figure 8 Insert Jumper for Max Brightness LC1200R User's Guide 021-0183-00 Rev A 19 of 29 6. 3 Dimming 6. 3. 1 Photodiode Board and Automatic Dimming Connector The photodiode board must be mounted in the user's system so that the photodiode is exposed to the ambient light. In bright conditions, the LC1200R will adjust to maximum brightness. [. . . ] dB (Decibel): A measure of the ratio of two signals. The dB value is 20 x log10 of a voltage or current ratio or 10 x log10 of a power ratio. Foot-Candle [fC]: A unit of illumination equal to the illumination which occurs when uniformly distributed luminous flux is impinging on an area at a rate of one lumen per square foot. Foot-Lambert [fL]: A unit of luminance equal to the uniform luminance of a perfectly diffusing surface emitting or reflecting luminance flux at the rate of one lumen per square foot. [. . . ]
