Ckingway HDMI Displaysare designed to work with theRaspberry Pior embedded system, single board computers (or desktop/laptops) which with HDMI output. This series display modules come with a control board with HDMI interface; it is designed to make Raspberry Pi usage become easily.

IPS, also known as In-Plane Switching,is a type of monitor display and screen technology. More specifically, an IPS panel is a type of TFT LCD (or "active matrix" LCD). LCD, or Liquid Crystal Display, is the use of light modulating properties from unlit liquid crystals for providing a flat panel or electronic visual display.

Ckingway offers a full range of wide temperature TFT LCD modules; available sizes are including 3.5", 4.3", 7". These TFT modules can be operating at Wide Temperature Range from -30℃ to 80℃ or up to 85℃. Related Product Keyword :

The RPi LCD can be driven in two ways: Method 1. install driver to your Raspbian OS. Method 2. use the Ready-to-use image file of which LCD driver was pre-installed.

2) Connect the TF card to the PC, open the Win32DiskImager software, select the system image downloaded in step 1 and click‘Write’ to write the system image. ( How to write an image to a micro SD card for your Pi? See RPi Image Installation Guides for more details)

3) Connect the TF card to the Raspberry Pi, start the Raspberry Pi. The LCD will display after booting up, and then log in to the Raspberry Pi terminal,(You may need to connect a keyboard and HDMI LCD to Pi for driver installing, or log in remotely with SSH)

This LCD can be calibrated through the xinput-calibrator program. Note: The Raspberry Pi must be connected to the network, or else the program won"t be successfully installed.

To interface any random piece of hardware with a raspberry pi you need to know a few things 1) voltage limits, 2) pinout (you can kill any device by swapping GND and Vcc, 3) the interface (SPI, I2C, 1-wire, USB, 8-bit) and 4) the bytes you need to send to the device to control it.

The makers of reliable, well documented devices publish all of that information in a document called a datasheet. It tells you what you need to know to a) wire it to your RPi and b) drive it from software.

For something random bought from some unknown Chinese vendor on eBay you may not get that info. For something bought from Adafruit or CPC/Farnell/Element14 you are 100% guaranteed to get the datasheet, you may even get pictorial wiring diagrams and software code samples to drive the devices they"re selling.

A parallel RGB interface up to 24 bits is available on all Raspberry Pi boards with the 40-way header (A+, B+, Pi2, Pi3, Zero) and the compute module. This interface allows to connect parallel RGB displays to the Raspberry Pi GPIO either in RGB24 (8 bits for red, green and blue) or RGB666 (6 bits per color) or RGB565 (5 bits red, 6 green and 5 blue).

This interface is controlled by the GPU firmware and can be programmed by a user via special config.txt parameters and by enabling the correct Linux device tree overlay.

This mode is accompanied by new overlays, which allow to produce an RGB signal thanks to the VGA666 (get the 666 passive VGA adapter for Raspberry-Pi B+ : code and hardware).

A number of people have used a Motorola Atrix Lapdock to add a screen and keyboard with trackpad to RasPi, in essence building a RasPi-based laptop computer. Lapdock is a very clever idea: you plug your Atrix smart phone into Lapdock and it gives you an 11.6" 1366 x 768 HDMI monitor with speakers, a keyboard with trackpad, two USB ports, and a large enough battery for roughly 5 hours of use. The smart phone acts as a motherboard with "good enough" performance. The advantage over a separate laptop or desktop computer is that you have one computing device so you don"t need to transfer files between your phone and your desk/laptop.

Unfortunately for Motorola, Lapdock was not successful (probably because of its US$500 list price) and Motorola discontinued it and sold remaining stock at deep discounts, with many units selling for US$50-100. This makes it a very attractive way to add a modest size HDMI screen to RasPi, with a keyboard/trackpad and rechargeable battery power thrown in for free.

Lapdock has two connectors that plug into an Atrix phone: a Micro HDMI D plug for carrying video and sound, and a Micro USB plug for charging the phone and connecting to the Lapdock"s internal USB hub, which talks to the Lapdock keyboard, trackpad, and two USB ports. With suitable cables and adapters, these two plugs can be connected to RasPi"s full-size HDMI connector and one of RasPi"s full-size USB A ports.

The RasPi forum has a long thread on Lapdock with many useful suggestions, photos, and links: I made a Raspberry PI Laptop. There"s also a good "blog entry at element14 with photos and suggestions of where to get cables and adapters: Raspberry Pi Laptop. TechRepublic has a tear-down article with photos of Lapdock internal components here: Cracking Open the Motorola Droid Bionic Lapdock. Paul Mano has a wealth of photos of Lapdock innards at Motorola Atrix Lapdock mod projects.

Lapdock uses the HDMI plug to tell if a phone is plugged in by seeing if the HDMI DDC/CEC ground pin is pulled low. If it"s not, Lapdock is powered off. As soon as you plug in a phone or RasPi, all the grounds short together and Lapdock powers itself on. However, it only does this if the HDMI cable actually connects the DDC/CEC ground line. Many cheap HDMI cables do not include the individual ground lines, and rely on a foil shield connected to the outer shells on both ends. Such a cable will not work with an unmodified Lapdock. There is a detailed "blog entry on the subject at element14: Raspberry Pi Lapdock HDMI cable work-around. The "blog describes a side-benefit of this feature: you can add a small power switch to Lapdock so you can leave RasPi attached all the time without draining the battery.

The Lapdock Micro USB plug is the upstream port of Lapdock"s internal USB hub, and connects to one of RasPi"s full-size USB ports. Lapdock is not USB compliant since it provides upstream power on its Vbus pin. Lapdock uses this to charge the Atrix phone. You can use this feature to power RasPi if you have a newer RasPi. The original RasPi rev 1 has 140 mA polyfuses F1 and F2 to protect the USB ports, which are too small for powering RasPi using upstream power. Newer RasPis replace F1 and F2 with zero Ohm jumpers or eliminate them entirely, which allows Lapdock to provide power. If you don"t mind modifying your original RasPi, you can add shorting jumpers over F1 and F2 or replace them with higher-current fuses.

What gets powered on depends on whether Lapdock is open or closed. If it"s open, the screen and all Lapdock USB ports are powered. If you close Lapdock, the screen and full-size USB ports are powered down, but the Micro USB still provides upstream power. This is for charging an Atrix phone. When you open or close Lapdock, the Micro USB power switches off for about a second so if your RasPi is connected it will reboot and you may have a corrupted file system. There"s discussion about this at the RasPi forum link, and someone has used a supercapacitor to work around the problem: Raspberry Pi lapdock tricks.

When you do not connect a HDMI monitor, the GPU in the PI will simply rescale (http://en.wikipedia.org/wiki/Image_scaling) anything that would have appeared on the HDMI screen to a resolution suitable for the TV standard chosen, (PAL or NTSC) and outputs it as a composite video signal.

The Broadcom BCM2835 only provides HDMI output and composite output. RGB and other signals needed by RGB, S-VIDEO or VGA connectors are however not provided, and the R-PI also isn"t designed to power an unpowered converter box.

Note that any conversion hardware that converts HDMI/DVI-D signals to VGA (or DVI-A) signals may come with either an external PSU, or expects power can be drawn from the HDMI port. In the latter case the device may initially appear to work, but there will be a problem, as the HDMI specs only provide in a maximum of 50mA (@ 5 Volt) from the HDMI port, but all of these adapters try to draw much more, up-to 500mA, in case of the R-PI there is a limit of 200mA that can be drawn safely, as 200mA is the limit for the BAT54 diode (D1) on the board. Any HDMI to VGA adapter without external PSU might work for a time, but then burn out D1, therefore Do not use HDMI converters powered by the HDMI port!

The solution is to either only use externally powered converters, or to replace D1 with a sturdier version, such as the PMEG2010AET, and to replace the power input fuse F3 with a higher rated one, as the current one is only 700mA, and the adapter may use 400mA itself. Also notice that the R-PI"s power supply also must be able to deliver the extra current.

Alternatively, it may be possible to design an expansion board that plugs into the LCD headers on the R.Pi. Here is something similar for Beagleboard:

The schematics for apples iPhone 3gs and 4g suggest they speak DSI, thus they can probably be connected directly. The older iPhones use a "Mobile Pixel Link" connection from National Semiconductor. The 3GS panel (480×320) goes as low as US $14.88, while the 4G one (960×640, possibly the LG LH350WS1-SD01, with specifications) can be had for US $17.99 or as low as US $14.28. The connectors used might be an issue, but this connector might fit. Additional circuitry might be necessary to provide the display with required 1.8V and 5.7V for operation, and an even higher voltage for the backlight.

The Raspberry Pi provides one clock lane and two data lanes on the S2 connector, as can be read from the schematics. It is currently unknown whether this is enough to drive the iPhone 4G screen, as that screen seems be driven with three data lanes in its original application.

I2C/SPI ADC can be used to interface 4 pin resistive Touch Screens, For example STMPE812A. Texas Instruments has a solution for 4 or 8 wire touchscreens using their rather cheap MSP4309.

These have controllers and interfaces for feeding in text (and symbols). Common screen sizes include 16x2 to 40x4. They"re often seen in keypads, industrial machines, cash registers, laser printers etc.

Parallel interface displays can be found in many sizes, usually up to 7" and more. Parallel interfaces are usually 8 or 16-bits wide (sometimes 18 or 24-bit wide), plus some control-lines. The Raspberry Pi P1-connector does not contain enough GPIOs for 16-bit wide parallel displays, but this could be solved by borrowing some GPIOs from the CSI-connector or from P5 (on newer Raspberry Pis). Alternatively, some additional electronics (e.g. shift-registers or a CPLD) can be used, which could also improve the framerate or lower the CPU-load.
