Depending on the panel architecture, between 4 and 18 different gamma voltages may be needed. These gamma voltages provide the reference voltages for the column driver RDACs. Due to the capacitive nature of LCD panels, it is necessary for these drivers to provide high capacitive load drive. In addition to providing gamma reference voltages, these parts are also capable of providing the VCOM voltage. VCOM is the center voltage common to all the LCD pixels. Since the VCOM circuit is common to all the pixels in the panel, the VCOM driver is designed to supply continuous currents up to 35 mA. INPUT The ADD8704 has four amplifiers specifically designed for the needs of an LCD panel. Figure 36 shows a typical gamma correction curve for a normally white twisted nematic LCD panel. The symmetric curve comes from the need to reverse the polarity on the LC pixels to avoid “burning” in the image. The application therefore requires gamma voltages that come close to both supply rails. To accommodate this transfer function, the ADD8704 has been designed to have four different amplifiers in one package. VDD VG1 GAMMA VOLTAGE VG2 Amplifier D has an NPN follower input stage. This covers the upper rail to GND plus 1.7 V. This amplifier is suitable for the upper range of the RDAC. OUTPUT The outputs of the amplifiers have been designed to match the performance needs of the gamma correction circuit. All four of the amplifiers have rail-to-rail outputs, but the current drive capabilities differ. Since amplifier A is suited for voltages close to VSS (GND), the output is designed to sink more current than it sources; it can sink 15 mA of continuous current. Likewise, since amplifier D is primarily used for voltages close to VDD, it sources more current. Amplifier D can source 15 mA of continuous current. Amplifiers B and C are designed for use as either midrange gamma or VCOM amplifiers. They therefore sink and source equal amounts of current. Since they are used as VCOM amplifiers, they have a drive capability of up to 35 mA of continuous current. The nature of LCD panels introduces a large amount of parasitic capacitance from the column drivers as well as the capacitance associated with the liquid crystals via the common plane. This makes capacitive drive capability an important factor when designing the gamma correction circuit. IMPORTANT NOTE VG3 VG4 VG5 VG6 VG7 VG8 VG9 0 16 32 GRAY SCALE BITS 48 64 00001-0-038 VG10 VSS Amplifier C is a rail-to-rail input range that makes the ADD8704 suitable for use anywhere on the RDAC as well as for VCOM applications. Figure 36. LCD Gamma Correction Curve Amplifier A has a single-supply PNP input stage followed by a folded cascode stage. This provides an input range that goes to the bottom rail. This amplifier can therefore be used to provide the bottom voltage on the RDAC string. Amplifier B (PNP folded cascode) swings to the low rail as well, but it provides 35 mA continuous output current versus 15 mA. This buffer is suitable for lower RDAC range, middle RDAC range, or VCOM applications. Because of the asymmetric nature of amplifiers A and D, care must be taken to connect an input that forces the amplifiers to operate in their most productive output states. Amplifier D has very limited sink capabilities, while amplifier A does not source well. If more than one ADD8704 is used, set the amplifier D input to enable the amplifier output to source current and set the amplifier A input to force a sinking output current. This means making sure the input is above the midpoint of the common-mode input range for amplifier D and below the midpoint for amplifier A. Mathematically speaking, make sure VIN > VS/2 for amplifier D and VIN < VS/2 for amplifier A. Figure 37 shows an example using 4 ADD8704s to generate 10 gamma outputs. Note that the top three resistor tap-points are connected to the amplifier D inputs, thus assuring these channels will source current. Likewise, the bottom three resistor tap-points are connected to the amplifier A inputs to provide sinking output currents.
