Black Side Gamma Measurement Method

Measure the output voltages y1 to y10 which correspond to the input voltages a1 to a10 using SG8 as the input signal. (Measure the voltage from the reference level. Label the white side from the reference level as positive, and the black side as negative.) Select the two points where | yn – yn–1 | (n = 2 to 10) is a maximum, and label these points yk and yk – 1. Also, label the input voltages which correspond to yk and yk – 1 as ak and ak – 1, respectively.

Next, measure the output voltages y1 to y10 which correspond to the input voltages a1 to a10 using SG9 as the input signal. Select the two points where | yn – yn – 1 | (n = 2 to 10) is a maximum, and label these points yh and yh – 1. Also, label the input voltages which correspond to yh and yh – 1 as ah and ah – 1, respectively.

From the above:

Maximum gain GM = (yk – yk – 1)/(ak – ak – 1) Minimum gain GN = (yh – yh – 1)/(ah – ah – 1)

The black side gamma gain is defined as the ratio of the maximum gain to the minimum gain. In other words:

Gamma gain = 20 log (GM/GN)

The gamma breakpoint is defined as the intersection between the straight line passing through points (ak, yk) and (ak – 1, yk – 1) and the straight line passing through points (ah, yh) and (ah – 1, yh – 1). In other words:

Gamma breakpoint = (GM ∗ GN ∗ (ak – ah) – GN ∗ yk + GM ∗ yh)/(GM – GN)

Description of Operation

Reference signal

The reference level is inserted into the RGB signal by inputting the XCLP2 signal shown below during the RGB input signal pedestal level interval. Gamma compensation and clamping operation are performed based on this level.

Bright adjustment

The position of the RGB signal relative to the reference level changes according to the voltage applied to RGB MBRT (Pin 1). Bright can be controlled without changing the γ characteristics to the panel because the input bias is changed with the breakpoint for output kept constant.

Gamma compensation

The gamma compensation curve establishes the gain change points (breakpoints) on both the black and white sides from the reference level. The black and white side gains and the black and white side gain change points can each be adjusted independently.

Sample-and-hold, gain control and pedestal clamp

Since sample-and-hold circuits are established in the R, G and B lines and each of these circuits is operated by an independent pulse, the delay can be set freely. In addition, the pulse leak is canceled by establishing a sample-and-hold circuit in the clamp loop and inputting the differential input of the gain control circuit.

SID output

The CXA1853Q outputs a side black signal for 4:3/16:9 aspect conversion. The black level is adjusted by the SID CTR pin. In addition, the PRG level can be set in part of the side black signal by inputting the PRG pulse. The PRG level is adjusted by the PRG CTR pin. The relationship between each input and output is as shown in the figure below.

Signal center control

The RGB and SID output center voltages are adjusted by the SIG CENT CTR (Pin 37). When SIG CENT CTR is preset, the output pin center voltage goes to VCC2/2.

Output clamp

The average value of each RGB and SID output signal is detected with external RC circuits and input to the RGB CLP and SID CLP pins. Then the center voltage offsets among R, G, B and SID outputs are reduced by feedback which equalizes these detected values and the signal center voltage set by the SIG CENT CTR pin.

Notes on Operation

1) R IN (Pin 9), G IN (Pin 10), B IN (Pin 11) input signal impedance An external capacitor is used as the hold capacitor for the clamp at the input of this IC. Therefore, the input signal impedance must be sufficiently low (75Ω or less) and the external capacitor must have a small leak current.

2) Clamp hold capacitors (Pins 51 to 53 and 65 to 67) The external capacitors connected to these pins must have a small leak current.

3) R, G, B, SID OUT load capacitance The output signal will tend to oscillate if the R, G, B and SID OUT load capacitance increases. Be sure to insert a 100 to 220Ω resistor in series to these output pins, and design to keep the load capacitance from exceeding 30pF.

4) External capacitor at the output The leak current absolute value and tolerance for the R, G, B and SID OUT average value detecting capacitors should be small. Note that if there is an offset in the leak current between R, G and B, offset voltage is also generated between R, G and B in the external resistor, which causes a DC offset of the output signal.

5) GND and power supply pins Pins 12, 22, 34, 48, 55 and 64 (GND) should be set to the minimum identical potential applied to the IC, and should not be left open. In addition, the potential at Pins 8, 18, 50 and 62 should be the same.
