1. General Description
The HX8257-A is a single chip digital driver supporting 480RGBX272 or
480RGBX240 resolution. The single chip includes Source, Gate, TCON, and Power
circuits. The driver receives 24-bit digital display data with single clock edge and
generates corresponding 64 level gray scale voltage outputs with dithering function to
realize 16M colors display. Positive and negative polarity voltages can be alternately
output from each channel in line (row) inversion driving method.
The HX8257-A can be applied on dual gate TFT LCD panel. Source line is half with
720 channels and gate line is double with 544 or 480-channel outputs.

7.2 VCOM block
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.

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

Figure 7.12 PWM Block
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.

In serial interface (PS=”L”), 8-bit data are transferred into the HX8257-A through
D07~D00 pins. The data are latched sequentially for display Rn, Gn, Bn, n=1, 2 … 480
when LR=”H”, and for Bn, Gn, Rn, n=480, 479, 478 … to 1 when LR=”L”.

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.

CLK_TRG=1: Data sampling at the CLK falling edge.
CLK_TRG=0: Data sampling at the CLK rising edge.
VSP: When VSP=0, VSYNC is negative polarity. When VSP=1, VSYNC is positive
polarity.
HSP: When HSP=0, HSYNC is negative polarity. When HSP=1, HSYNC is positive
polarity.
DEP: When DEP=0, DEN is negative polarity active. When DEP=1, DEN is positive
polarity active.
DEO: When DEO=0, VSYNC/HSYNC are also needed in DE mode. Under this
condition, vertical back porch is defined by VBP[6:0] and the horizontal first valid
data is defined by DE signal. When DEO=1, only DEN signal is needed in DE

If you want to check if the OTP cell is still available for COMC/COMPP programming,
you can read the current status from R61h shown below. R61h is only for read.

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.
Step VMC OTP Operation
1 Power up the module. Set nOTP=1 and find out the appropriate value of VMC[4:0] and power
off the system.
2 Power up the system with VDD=VDDIO=2.5V. If REG bit=1, set R02h=16’h3662.
3 Set appropriate values found from step 1 to register of VMC (R06h)
4 Set 04h=16’h0001 to stop internal power circuit. Wait 0.5s.
5 Set R60h=16’h8000
6 Set R60h=16’hC000
7 Connect 7.3V to VGH and 0V to VGL
8 Set R60h=16’hC200
9 Set R60h=16’hC280
10 Wait 200us for completing this program
11 Set R60h=16’hC200
12 Remove 7.3V from VGH and 0V from VGL
13 Set R60h=16’h8200
14 Set R60h=16’h0200
15 Set R60h=16’h0040
16 Set R60h=16’h0000
Step VDV OTP Operation
1 Power up the module. Set eOTP=1 and find out the appropriate value of VDV[4:0] and power
off the system.
2 Power up the system with VDD=VDDIO=2.5V. If REG bit=1, set R02h=16’h3662.
3 Set appropriate values found from step 1 to register of VDV (R06h)
4 Set 04h=16’h0001 to stop internal power circuit. Wait 0.5s.
5 Set R60h=16’h8000
6 Set R60h=16’hC000
7 Connect 7.3V to VGH and 0V to VGL
8 Set R60h=16’hC000
9 Set R60h=16’hC080
10 Wait 200us for completing this program
11 Set R60h=16’hC000
12 Remove 7.3V from VGH and 0V from VGL
13 Set R60h=16’h8000
14 Set R60h=16’h0000

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.
