The LC640.480.33-AC is a 1000 nit 10.4" diagonal VGA color AMLCD flat panel display module intended for commercial applications requiring outdoor viewability and long life. Special attention to the total backlight design gives the display a wide, “single- BEF” viewing angle while maintaining luminance efficiency greater than 45 nit/W. The display is convection cooled and does not require a fan, yet features a wide operating temperature range. It is lightweight, compact, and rugged, and includes

Installation and Handling Do not drop, bend, or flex the display. Do not allow objects to strike the surface of the display. using all four mounting hole locations. There are two recommended mounting configurations as shown in 1 using the hardware listed in Table 1 below. Appropriate changes to these mounting configurations may be needed to meet specific requirements or applications. Figure 1 . Mounting Options.

Vent Clearance The LC640.480.33-AC display is a wide temperature display utilizing convection cooling. It is imperative to allow ambient air unrestricted access to the cooling vents in order to reliably operate the display at high temperatures The vents for the lamp cavity are along the top and bottom edges of the display with the openings facing the rear. The vents for the inverter cavity are along the top and bottom faces of the display: four along the top surface and four along the bottom sur

Allowing V L L to remain “on” for a long period of time after video signals are removed—which stops the cell scanning—may produce a latent image. In addition, there is a restriction regarding dropouts on the V supply as illustrated in 3 (“Vcc”= V ). This is L L related to the reset circuit for the LCD’s internal logic. If a

Video Characteristics Colors are developed in combination with 6-bit signals (64 steps in grayscale) of each primary red, green, and blue color. This process can result in up to 262,144 (64x64x64) colors. The mapping of the eighteen video data inputs is shown in Table 12 .
