VCOM Adjust Circuit
You can use internal circuit to generate COMPP and COMC voltage level. Register
VDV[4:0] and VMC[4:0] are used to adjust COMPP and COMC voltage. If you want to
set COMPP and COMC voltage level from external, just set VDV[4:0]=00000 and
VMC[4:0]=00000. Then you can input COMPP and COMC from hardware pins. The
HX8257-A has a regulator circuit for VGR output power level. Connect VGR with
outside resistor strings. These resistor strings can generate COMPP and COMC
voltage levels for internal VCOM generation circuit. VGR voltage level is 4.5V. (Typ.)
If COMC/COMPP is generated internally, VGR circuit will be disabled.

7.5.2 Gamma adjustment register
This block is the register to set up the grayscale voltage adjusting to the gamma
specification of the LCD panel. This register can independent set up to
positive/negative polarities and there are three types of register groups to adjust
gradient, amplitude, and micro-adjustment on number of the grayscale,
characteristics of the grayscale voltage. (Use the same setting for Reference-value
and R.G.B.) Following graphics indicates the operation of each adjusting register.
Figure 7.11 Gamma Adjustment Function
7.5.2.1 Gradient adjusting register
The gradient-adjusting resistor is to adjust around middle gradient, specification of
the grayscale number and the grayscale voltage without changing the dynamic range.
To accomplish the adjustment, it controls the variable resistors in the middle of the
ladder resistor by registers (PRP(N)0 / PRP(N)1) for the grayscale voltage generator.
Also, there is an independent resistor on the positive/negative polarities in order for
corresponding to asymmetry drive.
7.5.2.2 Amplitude adjusting register
The amplitude-adjusting resistor is to adjust amplitude of the grayscale voltage. To
accomplish the adjustment, it controls the variable resistors in the boundary of the
ladder resistor by registers (VRP(N)0 / VRP(N)1) for the grayscale voltage generator.
Also, there is an independent resistor on the positive/negative polarities as well as
the gradient-adjusting resistor.
7.5.2.3 Micro adjusting register
The micro-adjusting register is to make subtle adjustment of the grayscale voltage
level. To accomplish the adjustment, it controls each reference voltage level by the 8
to 1 selector towards the 8-level reference voltage generated from the ladder resistor.
Also, there is an independent resistor on the positive/negative polarities as well as
other adjusting resistors.

7.5.3 Ladder resistor / 8 to 1 selector
This block outputs the reference voltage of the grayscale voltage. There are two
ladder resistors including the variable resistor and the 8 to 1 selector selecting
voltage generated by the ladder resistor. The gamma registers control the variable
resistors and 8 to 1 selector resistors. Also, there has pin (EXVR) that can be
connected to VSS or an external variable resistor for compensating the dispersion of
length according to different panels.
Variable resistor
There are 3 types of the variable resistors that are for the gradient and amplitude
adjustment. The resistance is set by the resistor (PRP(N)0 / PRP(N)1) and (VRP(N)0
/ VRP(N)1) as below.

8 to 1 selector
In the 8 to 1 selector, a reference voltage VIN can be selected from the levels which
are generated by the ladder resistors. There are six types of reference voltage (VIN1
to VIN6) and totally 48 divided voltages can be selected in one ladder resistor.
Following figure explains the relationship between the micro adjusting register and
the selecting voltage.

The HX8257-A is built in 2 independent PWM control circuits. The internal reference
voltage is adjustable by FBA[2:0] and FBB[2:0] in R05h. By adjusting the voltage, you
can get different VO to meet your system application. For 1st PWM, the VO also can be
adjusted by DU[4:0] setting. (Input pins or register setting) This setting is combined with
CABC function to provide power for LED backlight. 2nd PWM is designed to generate
VCIX2J if charge pump circuit is not used.

The HX8257-A has 2 modes for input interface, parallel and serial interface. In
parallel interface (PS=”H”), 24-bit data are transferred into the HX8257-A each cycle
when DE is activated. D07 to D00 is displayed for R dot on panel, D17 to D10 are
displayed for G data, and D27 to D20 are displayed for B data. The relationship
between display data and source output is shown in the following figure.

7.7.2 Aging mode
If only CLK is sent into driver IC without VS, HS, and DE signals, the HX8257-A will
enter Aging Mode after power on. In Aging mode, the display picture can change
automatically or be controlled manually by access register R04h.
7.7.3 TCON power on/off control
The HX8257-A has a power ON/OFF sequence control function. When DISP pin is
pulled “H”, blank data is outputted for 10-frames first, from the falling edge of the
following VSYNC signal. Similarly, when DISP is pulled “L”, 10-frames of blank data
will be outputted from the falling edge of the following VSYNC, too. The blank data
would be gray level 0 for normally black LC (NBW=”H”), and be gray level 255 for
normally white LC (NBW=”L”).

8. SPI Register
The HX8257-A is internally initialized by the global reset signal, RESETB. The reset
input must be held for at least 1ms after power is stable.
HX8257-A supports 24-bit serial bus interface. 24-bit data are latched by SCL’s rising
edge step-by-step. Serial bus interface is active while CSB=L (from CSB’s falling to
CSB’s rising). After CSB has transmitted twenty-four units of CLK, it has to change into
High.
Under the standard condition, the number of SCL is twenty-four units. While CSB=L, if
SCL < 24 cycles is input, then the input data won’t be latched and will become invalid
data. While CSB=L, if SCL >24 cycles is input, the 24-bit data in front of CSB’s rising
edge will become valid.

You can check the IDC/IDA bit to see if the VMC/VDV is still programmable or not. If
IDC=0, you can program new VMC[4:0] value to OTP. If IDC=1, it means that the
OTP cell have already programmed twice and you can’t program it any more. The
meaning of IDA is the same.

11. AC Characteristics
The HX8257-A both supports DE mode and Sync mode timing. The mode was
decided by DE signal internally. When DE is pulled low, the HX8257-A uses HS+VS
for timing control and this timing mode is sync mode. When DE is pulled high for
active data and pulled low for blanking data, the HX8257-A uses DE for timing control
and this timing mode is DE mode. The detail timing chart showed below.
