Development of Motherboards for Digital Signage

Feb. 20, 2020

The development of digital signage motherboards can be said to be a technological revolution, which has different application potentials in different environments. Nowadays, with the outstanding advantages of intelligence, interconnection, precision, and strong visibility, digital signage has become the second largest media form after TV, and it is also an important medium for the retail IoT, helping to achieve a true O2O business model. We expect that by 2020, there will be 50 million digital signage applications worldwide. High quality digital signage manufacturer share with you:

The digital signage motherboard uses Quanzhi A20 main control dual-core chip, integrates two ARM Mail-400MP graphics processing units, has strong video processing capabilities, and can be compatible with most video formats and decoding capabilities. Onboard Android 4.2 operating system, 1G of RAM and 4G of ROM, can directly drive 15-55 inch LCD LCD screen, and support large-sized infrared touch screen; 4 USB ports and 4 UART expansion ports, can meet different customers' needs Requirements; integrated RJ45 / WiFi / 3G in one, can adapt to a variety of network environments. At the same time integrated more external functions, TTL camera, human infrared sensor, 4 VIDEO input functions. Supports timing hard power on and off functions.

The Android platform now firmly occupies half of today's intelligent system platforms. It is a well-deserved boss in the field of smart phones. It is only the past two years that the advertising industry has been vying to attribute it to the company. "Industry orientation", the great promise of Android OS is an indisputable fact.

The Windows platform represents the traditional application board of the digital signage advertising machine industry. It has been widely used because of its powerful functions and stable performance, but it has been suppressed with the rise of the Android platform in recent years, and its expensive cost has led to its market. The share is getting worse.

High Brightness Digital Signage

High Brightness Digital Signage

Interface classification:

LCD screen interfaces mainly include LVDS, HDMI, and VGA interfaces. Among them, the number of LCD screen interfaces used in digital signage motherboards is the most widely used. LVDS has become more and more widespread with the rise of high-definition televisions and the gradual unification of standards. In comparison, VGA screens are used less and less.

Audio output interface:

GENIVI's open source middleware will be extended to support Android Auto integration, including authentication, audio, video, touch screen input and microphone interaction.

Network Interface:

The network interfaces mainly include RJ45 Ethernet, WIFI, Bluetooth, and 3G interfaces. Among them, RJ45 is mainly 100M and Gigabit standards. WIFI is mainly used in building systems where Ethernet is difficult to lay out, while 3G is used in mobile spaces with more complex environments, such as billboards in bus systems.

Development Status In 2013, digital signage has experienced particularly rapid growth in retail and IT spending. The fast-growing O2O model of e-commerce is also driving the evolution of the retail industry; with the help of integrated (AIO) flat panel displays and technological innovation, interactive electronic whiteboards, etc The use of high brightness digital signage is expanding day by day, and OPS is widely used in all-in-one systems.
