12.5-inch 4K IPS Touchscreen Display Works with Raspberry Pi 4B and other 4K SBC’s

There are plenty of displays for the Raspberry Pi boards, but if you are looking for a high-resolution display with capacitive multi-touchscreen it may be challenging to find. DFRobot may have what you are looking for though with a 12.5″ 4K IPS touchscreen display. The company says it’s compatible with Raspberry Pi 4B SBC, but since it comes with a mini HDMI input port, it should really work with any 4K capable SBC’s or computers. Key features & specifications: 12.5-inch IPS Pro display with 4K UHD (3840×2160) resolution, 60 Hz refresh rate,  HDR, 10-point touch 100% Color gamut, 400cd/㎡ brightness, 178° viewing angle Video Input – Mini HDMI input Audio – Built-in left and right loudspeaker, 3.5mm audio jack (output) USB – 2x USB Type-C ports both supporting touch/data and power Misc – Function menu button, power LED, power button Power Supply – Via USB-C port (USB-PD supported) Dimensions – 286 x 186 x 5.5 to 10 mm Material – […]

AirView Wireless Touchscreen Display Works with Phones, Laptops, Raspberry Pi, Etc. (Crowdfunding)

We’ve already written about several displays that take USB-C, HDMI or/and WiFi inputs to add a monitor to phones or computers including DUO add-on display and LAPSCREEN. AirView is another one of those and has launched on Kickstarter with a 13.3″ and 15.6″ Full HD versions featuring a touchscreen, built-in Miracast & AirPlay support, as well as HDMI and USB-C ports. It works with Android/iOS phones, traditional laptops & computers, SBC’s such as Raspberry Pi, and even game consoles. Two Airview models are available with the following hardware specifications: 15.6-inch model 1920×1080 resolution @ 60 Hz (4K model planned, but not available in KS) IPS display Multi-touch support Brightness – 250cd/m2 SRGB gamut – 98% Dimensions – 352 x 228 x 9.4 mm Weight – 1080 grams 13.3-inch model 1920×1080 resolution @ 60 Hz IPS display Multi-touch support Brightness – 300cd/m2 SRGB gamut – 100% Dimensions – 310 x 200 x 9.4 mm Weight – 850 grams Common Features Video […]

Manga Screen 2 is Smartphone Touchscreen Display with USB and HDMI Ports for Makers (Crowdfunding)

Most touchscreen displays aimed to be connected to a development board work through a display interface such as MIPI DSI or LCD RGB (and USB or I2C for touch support), and come with somewhat low resolution such as 800×480 which can be suitable for HMI applications. They also often don’t work with all boards due to the different interfaces used, and there’s no way to easily connect such small display to your computer. Taking those limitations into account, and since most boards and computers come with HDMI and USB ports, Elias Bakken and his team have added HDMI and USB ports to two smartphone displays, and Manga Screen 2 was born. The two displays – made by Sharp – have the following hardware specifications: Big (5.9”) Small (4.8”) Resolution 1920×1080 1280×720 FPS (max) 60 57 Color mode 24-bit PPI 376.2 307.9 Brightness 400 cd/m2 500 cd/m2 Contrast ratio 1000:1 800:1 Viewing angle 80 degrees Power draw (max.) 600 mA 520 […]

PQ Labs iStick A200 Android mini PC Connects to G4 Series Multi-Touch Screens

PQ Labs iStick A200 is a Rockchip RK3066 Android 4.1.1 mini PC with 2 GB RAM, 4 GB Flash, an HDMI (female) output, a USB 2.0 Host port, and a miniUSB port for power. Pretty boring stuff if you ask me… And I would not be writing about it, if the company hadn’t interfaced their infrared touch frames to this mini PC to allow 10-point multi-touch on a large screen or projector output, making it a pretty good solution for conferences and interactive digital signage. Before going further, let’s have a look at the details of specifications for the iStick A200: SoC – ARM Cortex A9 Dual Core @ 1.6Ghz with HyperSpeed (Equivalent to 2.0Ghz Dual Core) and Quad Core Mali400 GPU (cnxsoft: It has to be Rockchip RK3066) System Memory – 2 GB DRAM chipset Storage – 4 GB NAND flash + microSD socket (Up to 32 GB) Video Output – HDMI (female connector) Connectivity – WiFi (802.11 b/g/n) […]

Baanto ShadowSense Technology Enables Virtual Graffiti Drawings on Multitouch Displays

Baanto ShadowSense is a new 2D and 3D tracking technology using sensors that allow the system to determine the relative angle and as well as other characteristics of the shadow cast by an object. The system is provided as a frame with several sensors (4 typically) that you can connect via USB to your computer. It is an USB HID device, does not need drivers and support Windows XP/7, Linux and Android. This proprietary technology has the following key features: Traceability of multiple points or objects simultaneously (up to 5 points) Up to 10,000 fps. 16 MPixel resolution of shadow position. Simple algorithm that can be implement in 8-bit MCU. Low power draw. Less than $10 US per sensor. A typical configuration uses 4 sensors and plenty of small LED emitters as shown the illustration. Up to 1mm resolution of object position. No optical lenses are required The resolution is not quite at the level of the Leap Motion (0.01 […]

Toshiba Resistive Multi-touch Screen

Toshiba developed a proprietary algorithm for multi-touch resistive touchscreen and they exhibited a demo at Embedded World 2011. The hardware is based around Toshiba TMPA900 (ARM926EJ-S core running at 200 Mhz) and runs embedded Linux. This type of system is aimed at home appliances (washing machine, refrigerator…), industrial and medical applications and can be used with a pen, stylus or gloved hand. For example, a doctor wearing gloves would be able to use multi-touch gestures on such screens whereas it would not be possible on capacitive touchscreens or standard resistive touchscreens. It was not specified but I suppose that technology would only support 2 points since they only showed two fingers gesture in the demo. This should not be a problem for the type of application. An another advantage of this solutions is that it brings multi-touch technology to cost sensitive industrial applications. The technology is still under development and will be introduced to the market later this year. You […]

Digital Signage at CES 2011: HumanKiosk, ng Connect Program and Displays

Digital Signage solutions were also presented at CES 2011. Mediatile HumanKiosk Mediatile showcased its HumanKiosk solution, a digital signage system allowing face to face conversion (customer <-> representative) via 4G/LTE cellular networks at the Verizon Wireless and Alcatel Lucent booths. This system allows potential customers to ask questions about a particular product or service to a (hopefully) knowledgeable person. In case of very specific knowledge (e.g. some banking products), the company providing the products can save money (no need to have such persons in all branches) and provide a better customer service. Here’s a demo below of the HumanKiosk. ng Connect Program Alcatel-Lucent made several announcements about its ng Connect Program and three features are aimed directly at digital signage / dooh applications: Media Hotspot: Alcatel-Lucent, Atlantic Records and MediaTile developed a new jukebox concept that allows consumers to purchase their favorite music, movies and more via their mobile phone taking advantage of 4G/LTE or Wifi connectivity. Gametime Media Table: […]
