1. Overview
The display is a TFT active matrix electrophoretic display, with interface and a
reference system design. The 12.48” active area contains 984×1304 pixels, and has 1
-bit white/black and 1-bit red full display capabilities. An integrated circuit contains
gate buffer, source buffer, interface, timing control logic, oscillator, DC-DC, SRAM, LUT
, VCOM, and border are supplied with each panel.

Note 5-1: This pin (CSB) is the chip select input connecting to the MCU. The chip is
enabled for MCU communication only when CSB is pulled Low.
Note 5-2: This pin (DC) is Data/Command control pin connecting to the MCU. When the
pin is pulled HIGH, the data will be interpreted as data. When the pin is pulled Low, the
data will be interpreted as command.
Note 5-3: This pin (RST_N) is reset signal input. The Reset is active Low.
Note 5-4: This pin (BUSY_N) is BUSY_N state output pin. When BUSY_N is low, the
operation of chip should not be interrupted and any commands should not be issued to
the module.
The driver IC will put BUSY_N pin low when the driver IC is working such as:
- Outputting display waveform; or
- Programming with OTP
- Communicating with digital temperature sensor
Note 5-5: This pin (BS) is for 3-line SPI or 4-line SPI selection. When it is “Low”, 4-line
SPI is selected. When it is “High”, 3-line SPI (9 bits SPI) is selected. Please refer to
below Table.
