3 1 Introduction ED312TT2 is a reflective electrophoretic E Ink technology display module based on active matrix TFT substrate. It has 31.2" active area with 2560 x 1440 pixels, the display is capable to display images at 16 gray levels (4 bits) depending on the display controller and the associated waveform file it used. LVDS Driving Board is an E Ink display controller for E Ink panel. The data interface (LVDS) is comparable with normal LCD module. It could be developed a new application with same system structure like LCD. LVDS Driving Board only support 1280x720@60Hz resolution with 2 channels LVDS input. LVDS Driving Board will re-process the image to fit the resolution of 31.2 E Ink panel. 31.2" display panel is suitable for various applications, e.g. bus stop, museum etc (1) PACKAGE CONTENTS This demo kit contains the following: LVDS TCON board LVDS cable AD board ( HDMI input/lvds output) FFC cable*4 Adapter AC100V-240V to DC12V 5A Power cable 1

9 2 Hardware Guide This section describes the hardware setup of the 31.2 EPD display demo kit. (1) Hardware Requirements This demo kit should needs some items as following: 1. LVDS Driving Board E Ink display (EPD). 3. FFC cable 4. A/D Board or SOC platform with LVDS output interface 5. 12V power adaptor ED312TT2 EPD EVK LVDS System Board A/D Board with LVDS cable (No included in demo kit) 7

12V power adaptor FFC (2) Demo Kit Hardware Description 31.2 EPD display (ED312TT2) demo kit includes an FPGA driving board and an E Ink display adapter board.

The source of LVDS signal would be from A/D Board or SOC platform which support LVDS signal output. The FPGA driving board and A/D Board or SOC platform are connected via a LVDS cable.

10 12V power adaptor FFC (2) Demo Kit Hardware Description 31.2 EPD display (ED312TT2) demo kit includes an FPGA driving board and an E Ink display adapter board. The FPGA driving board and E Ink display adapter board are connected via a 50 pin FFC. The LVDS interface on the EVK is for image data receiving. The source of LVDS signal would be from A/D Board or SOC platform which support LVDS signal output. The FPGA driving board and A/D Board or SOC platform are connected via a LVDS cable. FPGA driving board receives the image data from LVDS interface and display on E Ink panel. There is a power circuit on LVDS Driving Board. The 12V power could be input from LVDS Driving Board or from LVDS cable. Note:Only allow one power path input for system (12V power from LVDS Driving Board or from LVDS cable), otherwise it will cause great damage for the system. Demo Kit 8

16 (2) How to operate the system LVDS Driving Board only support standard 2 channels LVDS signal input. There is no others control pin for LVDS Driving Board. LVDS Driving Board supports pattern mode for E Ink display. Pattern mode is 16 Gray levels with refresh update and image algorithm. Display mode will be auto enabled by auto mode selection function. This function is based on image content to select the display mode. If image content is static now and next image is changed, LVDS Driving Board will use pattern mode to make a full refresh update to show the new pattern on E Ink display. Note: 1. Lower LVDS frame rate Standard video frame rate (60Hz) from LVDS signal is too fast for EPD. It gets higher power consumption for system. If the speed of LVDS signal could be slowed down, it will get better power consumption. 2. Source video signal should be pure clear video signal for LVDS TCON Auto display mode selection is based on pure digital image signal. Unstable source video signal will cause auto mode selection fail. Analog video signal (VGA) is not allowed. High compression rate steaming video is not allowed, too. Only allow picture display. 3. Don t support handwriting mode 14
