2.0 DESCRIPTION
2.1. This application note provides guidance for interfacing, programming, and using the T-55264 and
T-55265-series displays. This document, along with the LCD module specification, references (a)
and (b), provides the application information needed design the display into electronic products.
This document IS NOT INTENDED to be the sole source of guidance for using the display.
2.2. The LCD module drawing provides size and information for the connector(s) built in the product.
The drawing does not provide the source for flexible printed circuits (FPC) that mate to the zero-
insertion force (ZIF) connectors since there are many potential sources available. The drawings
are provided within references (a) and (b).
2.3. The LCD Module Technical Specification provides electrical and optical performance
specifications, cosmetic specifications, and qualification information.
2.4. The T-55264- & T-55265-series displays include the following components:
262K Color thin film transistor (TFT) liquid crystal display panel.
Either a white cold cathode fluorescent lamp (CCFL) backlight [T-55264] or white light emitting
diode (LED) backlight [T-55265].
TFT timing controller, source drivers and gate driver.
DC-to-DC Boost Circuits to generate gate and source driver voltages. The displays require a
single 3.3 VDC source.
http://www.DataSheet4U.net/
2.5. The displays require additional components to integrate into the end unit:
CCFL backlight inverter (T-55264) or LED power supply / LED driver (T-55265).
Interconnect flat flex cable or flexible printed circuit.
Mounting screws
LCD controller.
3.0 PRINCIPLES OF OPERATION
3.1. A microprocessor writes to an LCD controller to configure it for operation. The configuration data
tells the device the polarity and sequencing of control signals and their timing. The
microprocessor then writes or ports image data to the LCD controller for storage in RAM. The
controller reads the RAM and automatically generates the control signals to write data to the
display. There are 18 data bits in RAM for each pixel location (6 red, 6 green, and 6 blue). 18
data bits are latched into the display with each pixel clock.
The controller generates control signals to tell the display when to begin writing a new line (HSYC)
and when to start writing a new page (VSYC). The DENA signal controls the horizontal position of
the data on the page.
The source driver in the display takes the data and performs a digital to analog voltage conversion
on the groups of six bits. The corresponding drive voltage controls the twist of the liquid crystal
and thus the light passage through it.
With 6 bits of data, 64 gray shades are generated for each red, green, and blue sub-pixel, within a
pixel. There are 262 K combinations or red, green, and blue shades possible.

3.2. TFT displays use TN-mode liquid crystals. Temperature compensation is not required as for
passive LCDs.
3.3. LCD controllers are often built-in microprocessors. .This design is often found on ARM-based
devices, high end microprocessors, and system on a chip (SOC) designs.
Sources for external LCD controller include:
Seiko Epson LCD Controllers
Fujitsu Graphics Controllers
Toshiba Automotive Graphics Controllers
4.0 MECHANICAL
4.1. The display is attached via 4 screws on the rear side. The screws self-tap into the polycarbonate
internal frame.
The recommended screw sizes are:

(4.4 to 5.0 pound-inch)
4.2. The connection between the display and the customers PCB is via a flexible printed circuit (FPC)
or flat flexible cable (FFC). The thickness of of the FPC / FFC is set by the connector mounted to
the display. The FPC / FFC must be 0.3 mm thick at the contact point stiffener.
http://www.DataSheet4U.net/
CAUTION
THE FPC / FFC MUST NOT TIGHTLY BEND AND PERMANENTLY DEFORM THE COPPER
TRACES (FORM A CREASE).
During bending, the inner side of the copper traces are compressed while the outer side is placed
in tension; fracturing the trace and electrically opening the circuit. The minimum bend radius
should be 10 times the thickness of the FPC / FFC to prevent permanent deformation.
Typical FPC are rated 0.3 mm thick at the contact point stiffener. This is not the bending point.
Most FPC are thinner away from that point. For an FPC that is 0.120 mm thick in the bend area,
the minimum bend radius is 1.2 mm for a 90 degree bend. A 180° bend requires a larger radius to
prevent creasing. Small radius bends greater than 90° should be formed ONCE and not unbent.
5.0 ELECTRICAL
5.1. INTERFACE CONNECTION & VOLTAGES
5.1.1. The displays interface via a 33-conductor FPC / FFC to ZIF connector mounted to the
display.
Kyocera Elco 08-6210-033-340-800 – 33 pin, zero insertion force (ZIF), right angle,
bottom contact, surface mount, 0.5 mm pitch FPC, 0.30 mm thick, with front slide lock.
5.1.2.
A major design consideration for the customer’s PCB is the contact location in the mating
connector. The display ZIF has contacts on the bottom (PCB) side. The designer must take
FPC bending and connector location into account and choose the correct contact location
when selecting connectors. If the FPC exits straight from the display with no bends, then a
top contact connector is required. If a single 180-degree bend is made, then a bottom
