1. Introduction
SSD1963 Eval Rev2A is a development board for Solomon SSD1963 display
controller which provides 1,215K byte frame buffer with parallel MCU interfaces
for RAM-less LCD panels up to 864x480 at 24-bit per pixel resolution. With linear
voltage regulators, LED backlight circuits, and FPC connectors for touch panels
all built-in, users are provided with all necessary circuitry for testing TFT panels
of different size with their own choice of host microcontrollers.
A representation of the board layout is shown in Figure 1.1. The board includes
these key features, as indicated in the diagram:

1. Voltage regulators for 5V, 3.3V, and 1.2V driving LED backlight (5V), interface
supply power for LCD and digital I/O (3.3V), as well as the core supply
voltage (1.2V) for SSD1963.
2. Four FPC connectors (J1~J4) for different LCD panels. There are dozens of
TFT pin-out definitions as there is no industrial standard for this. Only four
connectors will not cover all of the TFT interfaces but at least four panel sizes
have been verified including 3.5”, 4.3”, 5.6”, and 7” TFT panels on this
evaluation board.
3. Two FPC connectors (J5, J6) of bottom contact for touch panels. Some panels
have individual FPC for Touch Panel while others have Touch Panel signal
integrated with data bus on a single FPC. These FPC connectors of 0.5mm and
1.00mm pitch provide a convenient access to Touch Panel signals in case the
signals are separated from the data-bus-FPC. This is very common for large
panel size like 5.6” and 7” panels.
4. Two LED backlight circuits for
a. High voltage 20mA constant current white LED driver (CAT4237, On
Semiconductor Inc). The CAT4237 is a DC/DC step-up converter that
delivers an accurate constant current source driving 6 to 8 white LEDs
in series. Output of CAT4237 is routed to J3 and J4 for 4.3” and 3.5”
panels, respectively.
b. 22V high current boost white LED driver (CAT4139, On
Semiconductor Inc). The CAT4139 is a DC/DC step-up converter that
delivers an accurate constant current ideal for driving parallel strings
of up to five white LEDs in series or up to 22V. TFT panels of larger
size (>5.6”) require a lot more white LEDs than small panels. Let’s take
an example from our 7” TFT panel. The white LEDs are organized in 8
parallel groups of 3 LEDs in series as shown in Figure 1.2. The current
required is 160mA (20mA x8) and the voltage requirement is 9.9V.
The CAT4139 is capable of delivering 750mA with voltage as high as
22V under a single 5V DC supply. Output of CAT4139 is routed to the
high voltage connector J7.

5. Standard 40-pin 2.54mm box header for MCU interfaces. This box header
provides a direct stack with our PIC24/32 Eval RevC2 board via a flat cable
which is included with every board SSD1963 Eval Rev2A sold.

3. Software
Several demo programs are provided for quality assurance. These programs
have been developed under Microchip Graphics Library Version v2.00 with a low
level driver for SSD1963 developed by us.
However, I must emphasize that, it is not restricted to use Microchip’s
microcontrollers to interface the SSD1963. Any microcontroller or processor
that is able to generate the required control signal (CS#, DC, RD#, WR#, and
D[23:0]) will be able to drive SSD1963. There are few Graphical Libraries such as:
• Luminary (now belongs to Texas Instruments) Micro Graphics Library
o http://www.luminarymicro.com/products/stellaris_graphics_library.html
• Renesas Graphics Library
o http://america.renesas.com/fmwk.jsp?cnt=sw_lib_child.htm&fp=/products

• PEG embedded Graphical User Interface
o http://swellsoftware.com/products/
• Easy GUI by IBIS Solution ApS
o http://www.easygui.com
• emWin supplied by Segger Microcontroller GmbH & Co. KG
o www.segger.com
Some of these libraries are free as long as you would use their products while the
others provide port to various MCUs at a certain cost. Users may select their host
and decide which GUI is the best for the application. Microchip Graphics Library
has been chosen because it is free as long as the library will be embedded in
Microchip products.

4. Installing different LCD Panels
4.1 Installing 7” TFT panel TY700TFT800480
The TFT panel (model # TY700TFT800480Rev01) is a WVGA 262k color LCD
module. LED backlight and Touch Panel are connected by individual connectors.
Including the FPC for data, there are three connectors to be installed. Turning to
the bottom side of the LCD module, we will see a 40-pin bottom contact FPC
connector as shown in Figure 4.1. Most likely an 18cm flex cable has been
installed for you. If not, please connect it with the silver contacts of the flex cable
downwards. Figure 4.2 illustrates how the 7” TFT panel is connected.
