LC640.48 0.33-AC Operations Manual (OM600-01) 15 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.
LC640.480.33-AC Operations Manual (OM600-01) 16 Pixel Position The position of pixel data, relative to the color filter orientation and scan direction inputs is shown in Figure 8 . Refer to the timing diagrams in Figures 5, 6, and 7 for horizontal pixel position (D1 through D640), and for vertical line position (DH1 through DH480).
LC640.48 0.33-AC Operations Manual (OM600-01) 17 Video Connector (J3) Video signals and LCD display power (V L ) are applied via a polarized 34-pin dual-row 2 mm pitch header with gold plated (30 µ ") contact surfaces and ejector/latching ears.
LC640.480.33-AC Operations Manual (OM600-01) 18 Dimming Connector (J2) A dimming voltage or potentiometer, plus optional backlight mode and disable logic inputs are applied via J2, which is a polarized 5-pin inline, 2.5 mm pitch header, tin plated with a friction lock.
LC640.48 0.33-AC Operations Manual (OM600-01) 19 Optical Features Viewing Angle Viewing angles are defined per Figure 10 below: Figure 10 . Viewing Angles.
LC640.480.33-AC Operations Manual (OM600-01) 20 Backlight Dimming Modes The backlight may be operated in one of four modes without the use of jumpers or switches. The mode is selected based on the state of the /ABCOFF input and on whether the dimming input is left open or connected to a voltage source.
LC640.48 0.33-AC Operations Manual (OM600-01) 21 Method A represents sourcing the dimming input from a voltage source such as a DAC or analog op amp. The device should be powered from +5 Vdc such that the device’s output will not exceed the allowable input range of the dimming input.
LC640.480.33-AC Operations Manual (OM600-01) 22 Temperature Considerations Thermal Shutdown A thermal sensor referenced to the center of the backlight/inverter ECA prevents the inverter from starting at an ambient temperature of –30 ° C or below, and will shut off the backlight at an ambient temperature of approximately +90 ° C and above.
