BlitzWolf BW-PCM1 is an Inexpensive 11.6″ Portable Display

The BlitzWolf Portable Display The BlitzWolf BW-PCM1 is an 11.6″ portable monitor designed for function and performance. The versatile screen has a number of features that other portable monitors, don’t have. This expanded ability seems to usher in a new era of portable monitors.        The Idea Behind the Portable Display The BW-PCM1 was designed to a greater extent to use a gamer’s model for resolution at Full HD for 1920 x 1080 and auto-refresh at a range of 24 – 60 Hz. It is inexpensive and has a number of positive features and some negatives as well. Power Access The screen needs to be plugged into a power source and there is no indication that there will be a battery option. That is not to say never,  just at this time there is no battery available for the unit. The BW-PCM1 Cons The display is designed to be lightweight, and thin, but not the most in either …

Fingerprint Identification with STM32 MCU and Serial TFT LCD Module

STM32 Fingerprint TFT LCD

CNXSoft: This is a guest post by Amy working for STONE Technology, a company specializing in industrial liquid crystal display modules This month, I planned to develop a fingerprint door lock project. When I selected the fingerprint identification module, the project was suspended. However, I thought that since the fingerprint identification module had been purchased, I would simply test it. This fingerprint module can be easily purchased online, connected over UART to an MCU  board. It supports fingerprint scanning, fingerprint entry, fingerprint comparison, and fingerprint deletion. Since the fingerprint module manufacturer provides a demo program for STM32F103 series microcontrollers, I bought a small development board based on STM32F103C8T6. The demo program of the fingerprint module uses LED lights to prompt the user to enter the fingerprint and compare the status (success or failure). But I want to use an LCD display, so I chose a 480×272 resolution serial LCD display. The specific model of this display is STONE STVC050WT-01, which …

BOE Showcases Rollable Displays for Smartphones (Video)

BOE Rollable display

Companies have already announced foldable smartphones, but another type of smartphone may soon come to retail shelves as BOE showcased rollable displays for next generation smartphones at SID Display Week 2019. BOE, a China-based tech company, is a global leader in the semiconductor display industry. In addition they are an IoT company providing intelligent interface products. Also, they produce Interface Devices, Smart IoT Systems and Smart Medicine & Engineering Integration. In the video, you can see two different foldable phones, one which is  about 7.7 inches display but, can be folded into a 6 inches display. And another rollable smartphone, which is up to 12.9 inches, the main attraction of the day. The 12.9 rollable smartphone, although still a prototype and not ready for the market, showed a lot of potential.  With the plan to add more features to future versions, this smartphone, BOE is really heating things up. Additionally, it is good to know that the smartphone, despite not having …

$40 Elecrow 5″ HDMI Raspberry Pi Display Features Backlight Control, a Resistive Touch Panel

5-inch HDMI Display Backlight Control

There are plenty of small touch screen displays for Raspberry Pi board, including the official 7″ display that connects to the board’s MIPI DSI connector.  Some people may prefer getting a small HDMI display however, as it can be used with most devices with an HDMI input port, and the touch screen function may be achieved over USB, I2C or SPI depending on the design. Elecrow has just launched a new 5″ HDMI display with resistive touch screen designed for the Raspberry Pi boards, and whose main feature is to support backlight control over GPIO 11 in order to lower power consumption according to the announcement tweet from the company.   Specifications for RPD19048A display: Screen – 5″ TFT resistive touch screen display with 800×480 resolution @ 60 Hz; LCD Driver IC – Display Future ILI9486L (Likely wrong as this only supports 480×320 resolution) Touch controller – XPT2046 4-wire resistive touch controller Video Input – HDMI Power Supply – 5V/1A …
