Connect a 9.7″ Retina Display (iPAD 3/4) to Your Computer via a DisplayPort Adapter

One way to connect an extra Retina (2048×1536) display to your computer is to purchase Adafruit Qualia 9.7″ DisplayPort Monitor for $224.95. But in case your budget is limited, you could combine an old iPAD 3/4 display with AbuseMark 2048×1536 LCD to DisplayPort Adapter for 3,500 JPY ($29 US). If you don’t have an old iPAD, or would rather not dismantle your “old”-but-still-useful iPAD, you could purchase LG LP097QX1-SPC1/2, LG LP097QX1-SPA1/2/V, or Samsung LTL097QL01-W01 LCD panels instead for about $80 on Amazon US (LP097QX1 / LTL097QL01). If you live in Japan, AbuseMark also ships a complete kit for 12,000 JPY. Key features listed for the board: Video Input – DisplayPort Display Connector – 51-pin 0.3mm pitch FPC connector STM32F103CB 32-bit Cortex M3 MCU with native USB for firmware update and power/brightness/etc control Dual TI TPS61187 WLED drivers Power – USB or 5V-powered (separate connector) / 1.35A total current draw.

Board Bringup: LCD and Display Interfaces – ELCE 2011

Presentation “Board Bringup: LCD and Display Interfaces” by David Anders, Texas Instruments, at Embedded Linux Conference Europe 2011. Board bringup is one of the most under documented aspects of embedded development. This presentation looked at the various display technologies such as DisplayPort, DVI, LVDS, and other LCD interfacing methods with emphasis on how to bringup, debug, and validate them on new hardware. Using a case study, aspects such as interfacing timing, extended display identification data(EDID), and backlight controls have been discussed. Most embedded linux developers at some point in their career will be handed a piece of hardware that is untested. LCD bringup is one of the most challenging assignments for an embedded developer. This presentation intends to provide some core tools and methods for bringup of a new display interface.
