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

/mpumcu/h8_family/h8_lcd/child_folder/&title=Graphic%20Animation%2

• 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.

Figure 4.1 Bottom side of 7” TFT panel TY700TFT800480

Figure 4.2 Connect a 7” TFT panel to SSD1963 Eval Kit

User’s Guide of SSD1963 Eval Rev2A
Doc. version 1.0b 8th Feb 2010 Page 6

Important message: There are three 40-pin FPC connectors onboard. They are J1,
J2, and J3. They come from the same manufacturer of the same model but they
have been designed to connect different TFT panels. Don’t confuse them;
otherwise, your TFT panel may be damaged.

Connect the 18cm flex cable of TY700TFT800480 to only J1! This time, silver

contacts of the flex cable should be facing upwards. Then, J7 connection can be
made for backlight. Connector J7 is a high voltage connector which is wired to
CAT4139 for a driving current as high as 160mA. Figure 4.3 illustrates the
connections.

Finally, connect the FPC for Touch Panel to J5 as shown in Figure 4.4. Use a
tweezers to handle this part close to the tip (don’t clip on the soft cable part.)
Push gently the FPC into J5 with gold contacts down. Please do it slowly with

great care because this FPC is very fragile.

Doc. version 1.0b 8th Feb 2010 Page 7

4.2 Installing the 4.3” TFT panel TY430TFT480272

Installation of 4.3” TFT panel is much easier because the LED backlight, data, and
Touch Panel signals are all integrated on a single 40-pin FPC. Connection is made
to J3 as shown in Figure 4.5.

Figure 4.5 Connect 4.3” TFT panel TY430TFT480272 to J3

4.3 Installing the 3.5” TFT panel LVC75Z779V1S

Installation of 3.5” TFT panel is made to J4 on SSD1963 Eval Kit as shown in
Figure 4.6. This is the only 54-pin connector onboard with bottom contact. No
mistake can be made for this.

5. Connection to MCU

The MCU interface is routed on a standard 2x20 2.54mm box header. Figure

5.1 shows an extract from the schematic.

Figure 5.1 Schematic of the MCU interface

Important message:
a. VDD = 3.3V from the voltage regulator AMS1117-3.3V onboard
b. EXT_VIN = External voltage input from an external source applied at DC

input jack J1P. Therefore, if you have 7.5V DC applied to J1P, EXT_VIN at
pin 38 would be at 7.5V.

There are three label prefixes:

a. SSD_xxx : prefix for SSD1963 display controller
b. EVK_xxx : prefix for PIC24/32 Eval RevC2 demo board (hyperlink)

http://www.techtoys.com.hk/PIC_boards/PIC24-Eval-C/PIC24-Eval-RevC.htm

c. TP_xxx : prefix for Touch panel

The EVK prefixes are used to indicate how our PIC24/32 Eval Rev2C board is
connected to SSD_D[15:0] with various control signals. Figure 5.2 shows the
wiring to PIC24/32 Eval RevC2 board. A flat cable is provided for every SSD1963
Eval kit sold.

User’s Guide of SSD1963 Eval Rev2A
Doc. version 1.0b 8th Feb 2010 Page 9

The choice of 2.54mm box header allows you to connect the SSD1963 Eval Kit to
any microcontroller or evaluation platform.

Figure 5.3 shows the scenario when SSD1963 Eval Kit is hooked up with an
Atmel SAM AT91 mcu kit by jumper cables. Jumper cable set is also available
from our store at the following hyperlink:

6. Installing the hardware

Figure 6.1 shows the block diagram of the system.

Figure 6.1 Block diagram of SSD1963 Eval Rev2A

The board is powered from an external 7~9V DC with pin positive. This voltage is
regulated to 5V DC at U1P (AMS1117-5V) for two LED backlight circuits, CAT4237 and
CAT4139 and further stepped down to 3.3V for SSD1963 and TFT panels.

If the host PIC24/32 Eval board is used, power supply at 3.3V will be sourced from the

2.54mm interface header. Figure 6.2 illustrates the wiring with path of power supply.

7.2 Procedure

Download and uncompress the file GUIv200.rar to any location you find
convenient. For my case, it under

D:\Projects\SSD1963 Eval\MPLAB\GUIv200\Graphics AN1136\AN1136Demo PIC32.mcp.

Two folders, namely \Microchip and \Graphics AN1136 as shown in Figure 7.2
will be installed. The folder \Microchip contains the source code for the graphics
library and an individual project is located under \Graphics AN1136 folder.

The \Microchip folder is installed only once for version control.

By continuing with download and uncompress from Doc 05 to Doc 09, the
following folder hierarchy will be seen (Figure 7.3). Make sure all project folders

are located under the same path as the Microchip folder; otherwise, compilation
will fail due to missing source code location for individual project.

First, launch MPLAB and browse to your working directory. Open the project file
AN1136Demo PIC32 (or xxx PIC32.mcp) for PIC32.

Make sure no missing file message is created. Also make sure the correct MCU
has been selected under Configure→Select Device to make sure the MCU
PIC32MX360F512L has been chosen.
