LCD display driver solutions

Character drivers
Graphics drivers
These low-power CMOS LCD controller/drivers are designed to drive dot-matrix LCD displays. The PCF2113x controls
up to two lines of 12 or one line of 24 characters, with a dot format of 5 x 8, and supports up to 120 icons.
The icon-driving feature can also be used to drive a number of segments, such as a line of 7- or 14-segment digits.
The PCF2119x is the same as the PCF2113x, but controls up to two lines of 16 or one line of 32 characters and supports
up to 160 icons. Both devices are standalone ICs with on-chip generation of LCD bias voltages, including temperature
compensation. The result is fewer external components and lower current consumption. Both devices interface to
most microcontrollers using a 4- or 8-bit parallel bus or the two-wire I²C-bus. Both devices also include a character
generator and display alphanumeric and kana (Japanese) characters. Custom character sets can be provided on request.
Combining a number of digits results in a full-graphic block with up to 16 x 40 pixels. The block can be controlled by the
16-digit CGRAM, which can also be used to generate custom, user-specific characters. To reduce power consumption
during idle time, the Icon Mode can be used to show device activity status on the display.
Also known as dot-matrix drivers, these are low-power CMOS LCD row/column drivers, designed to drive dot-matrix
graphic displays at multiplex rates up to 80. They can drive a large number of icons, and can drive a series of
7- or 14-segment digits. Each driver is a standalone IC, including on-chip generation of VLCD and the LCD bias voltages.
The result is fewer external components and lower power consumption. Most of the drivers communicate with a
microcontroller using the two-wire, bidirectional I²C-bus; some use the SPI-bus or a parallel bus. Large display matrixes –
such as 65 x 133 or 80 x 128 – make it possible to display more text, and ensure that fonts are sharp and easy to read,
with almost invisible pixels.

LCD display drivers
Segment drivers
NXP’s standalone LCD display drivers bring high reliability and low power consumption to a broad range of applications.
They require few external components for operation, operate over a wide temperature range, support a wide range
of supply voltages, and integrate vital interfaces. They are available in several different packages and delivery forms,
to support various assembly technologies, and can be used in conjunction with an NXP RGB LED controller for LED
backlighting.
These peripheral devices can be interfaced to almost any LCD with low multiplex rates. They generate the drive signals
for any static or multiplexed LCD, with up to four backplanes and up to 160 segments, making it possible to drive up
to 640 elements at once. Some devices can be used to drive eight or 16 backplanes. Most drivers are easy to cascade
together for use with larger LCDs. Most of the devices communicate via a two-line I²C-bus; a driver for the SPI bus is
also available. Several features minimize communication overhead, including a display RAM with auto-incremented
addressing, hardware sub-addressing, and display memory switching (in static and duplex drive modes).
NXP’s portfolio includes segment, character, and graphic display drivers. NXP’s segment display drivers lead the industry
in terms of the number of segments that can be driven per device. That means more information can be displayed,
at a lower cost. For automotive applications, NXP even has options that are AEC-Q100 compliant, ensuring reliable
operation under the harshest conditions. NXP’s character display drivers can be configured to drive almost any character
set, including Japanese, and support a large number of icons. The graphic display drivers, for use with monochrome,
dot-matrix LCDs, are available in two resolutions: 34 x 128, and 80 x 128.
Key features

The NXP I2C-bus LCD driver evaluation board (OM6290)
demonstrates the features of NXP’s LCD drivers.
The board contains three displays, each controlled by an
I2C-bus LCD driver. One member of every driver family is
present, thus there is one segment driver, one character
driver and one graphic driver on board. In addition, the
segment display has a backlight driven by LED driver
PCA9633. All drivers are controlled by an LPC2148
microcontroller.
Key features
} Standalone LCD controller / driver
}Industry-leading in terms of number of segments that can be driven per device
} Internal LCD bias generation with voltage follower buffers
} Internal oscillator, with external clock also possible
} On-chip RAM with auto-incremental addressing for storing display data
} Cascadable with auto-incremented display data loading across device sub-address boundaries
} Versatile blinking modes
} AEC-Q100 compliant options for automotive applications
} Low power consumption
} I²C-bus, C-bus or SPI-bus interface
} Wide range of packages for different assembly technologies, including chip-on-glass (COG)
NEW:
PCA9620 – Automotive 60 x 8 segment driver for multiplex rates up to 1:8
This 60 x 8 LCD high-drive segment driver offers AEC-Q100 grade 2 compliance and is optimized for use in automotive applications
such as instrument clusters, car radios, and climate-control units. It also supports displays in demanding industrial applications,
including machine control systems and measuring equipment.
The PCA9620 generates the drive signals for static or multiplexed LCD containing up to 8 backplanes, 60 segments, and 480
elements. Housed in a single LQFP80 package, it can drive almost any LCD with low multiplex rates. It is compatible with most
microcontrollers and communicates via the two-line bidirectional 400 kHz I2C-bus.

NEW:
PCF8536 and PCA8536 – Automotive and industrial 40 x 8 segment driver with integrated PWM channels for LEDs
This advanced, highly integrated LCD controller drives up to eight backplanes, up to 44 segments, and up to 320 elements. It includes
an on-chip PWM controller for LED backlight illumination. The PWM controller has six outputs with 7-bit resolution (128 steps), and is
ideal for driving external transistors. Up to six independent channels can be configured. The 128 levels per channel can control two
RGB backlights with a spectrum of more than 2 million colors. Each channel can also be used for static LED drive or as a logic output.
Communication overheads are minimized by using a 320-bit display RAM with auto-incremented addressing. The device is available
in an industrial version (PCF8536, for white goods and consumer products) and in an automotive version (PCA8536, e.g. for car radios,
climate control and dashboard displays). The automotive type supports an extended operating temperature range up to 95 °C, and is
AEC-Q100 compliant.
Both types of the peripheral device are equipped with a low-power serial interface: either the two-line bidirectional I2C-bus (400 kHz) or
the three-line unidirectional SPI bus (5 MHz). The interface controls and drives almost any LCD display with multiplex rates up to 1:8.
