Newhaven Display has announced a new HDMI TFT module product line that greatly simplifies the process of connecting to the display. Rather than juggling an FPC ribbon cable with a middle-man controller board, you can connect an HDMI cable from your desired board or computer right into the TFT module. This makes it easy to interface with your display from the development and prototyping stages, all the way into final application production.
The ease-of-use of these new products follows through into touch panel integration as well. For both the resistive and capacitive (PCAP) touch panel options, USB-HID driver recognition is installed. Each of the touch panel modules are also each pre-calibrated in-house to the display they’re mounted on. This means that a simple USB to micro-USB cable just needs to be connected from your board with touch interaction output (such as Raspberry Pi) to the module and your touch interactivity is ready to go immediately.
The product line is made up of three 5″ TFT modules and nine 7″ TFT modules. The 5” versions all come with MVA technology (meaning exceptional 75° viewing at all angles) and your choice of capacitive, resistive or no touch panel. The 7” modules have the same selection of touch screen options, but also allow you to choose between standard, premium or sunlight readable TFT displays.
The boards that make up the new product line are Newhaven Displays’ own design and come with a number of features. On board DC power allows the display to perform at maximum capacity without worrying about a power supply bottleneck from elsewhere. The no-touch panel versions have just two simple connections required to get the module up and running, DC power and HDMI interface. The touch versions need an additional cable to utilize their touch functionality via USB-HID__three cables and you’re ready to go. The hardware is compatible with PC systems (Windows or Linux) as well as Single-Board-Computers (SBCs) like the RaspberryPi and BeagleBone.
The HDMI TFTs’ PCB boards also have four 3.5 mm mounting holes tooled right into the board itself–no bracket or casing required, just pop in any standard M3 screws. To ensure the highest quality and long-lasting performance, these modules use the reliable Texas Instruments TFP401A HDMI/DVI receiver and the TPS61165 LED driver.
On the boards, you’ll also find a switch for Pulse Width Modulation (PWM) to control the brightness output from the display backlight. All hardware is completely open source and available as a useful reference point for any interested user.
The wait for HDMI compatibility is over. Today is the day to start designing your projects with Newhaven Display’s new HDMI TFT Modules. Stop limiting yourself to the hassles of FPC cables and clunky controllers, just grab an HDMI cable and your set up is complete. It’s Newhaven Display’s product quality fused with the reliability of HDMI interface.
