Government affairs touch screen monitor

Government affairs touch screen monitor is a display terminal that integrates touch technology and is designed for government affairs service scenarios. It usually appears in the form of "touch query all-in-one machine" or "self-service terminal", and is used for information query, business processing, queuing, calling, etc., in order to divert the pressure of manual windows and improve work efficiency. The following is a summary of technical parameters, key points of model selection, brand products and procurement suggestions.

Core technical parameters

The government affairs scenario has high requirements on the stability, durability and display effect of the equipment, and the following indicators are usually paid attention to when purchasing:

Display parameters

Size: 21.5 inch, 23 inch, large screen inquiry machine can reach 55 inch, 65 inch or more

Resolution: medium and small size ≥ 1920 × 1080, large size ≥ 3840 × 2160 (4K)

Brightness: ≥ 350cd/m ², some government halls require ≥ 450cd/m ² to cope with strong light environment

Viewing angle: ≥ 178 °

Contrast; ≥ 1400:1, some high-end models can reach 12000:1

Touch parameters

Touch technology: infrared touch or capacitive touch, infrared touch is mostly used in government affairs scenes, with strong adaptability and long service life

Touch points: support more than 10 points, and some large screens require 20 points or even 40 points

Touch resolution: 32768 × 32768 (infrared) or 4096 × 4096 (capacitance)

Touch precision: ≤ 2mm, touch height ≤ 2.5mm

Surface material: tempered explosion-proof glass, Mohs hardness ≥ 7, light transmittance ≥ 88%

Service life: touch life ≥ 50 million times, and some infrared screens can reach 60 million times

Host and interface configuration

The government affairs terminal is usually equipped with an industrial control host. The common configuration is Intel i3/i5 processor, 8GB memory, and storage above 128GB SSD. Some require domestic operating systems or Android systems. In terms of interfaces, USB (≥ 2), HDMI, RJ45 network ports, VGA, etc. shall be reserved for interfacing with ID card readers, printers, scanning modules and other peripherals.

Key points of model selection

Size and installation method: 19 – 23 inch vertical or horizontal screen is commonly used for window inquiry desk; 43 – 55 inch vertical machine for hall guide; Large exhibition or conference scenes can be 65 – 86 inch wall mounted or mobile bracket. Some manufacturers support wall mounted/vertical/horizontal customization.

Selection of touch technology: infrared touch has low cost and strong adaptability, and is suitable for public scenes of high-frequency use; Capacitive touch experience is smoother, but the cost is higher. The government hall has a large flow of people, and infrared touch is a more secure choice.

Full fitting process: full fitting screen is preferred, which can reduce reflection, improve touch sensitivity, and have better visibility in strong light environment.

ICT adaptation: if the project requires localization, it is necessary to confirm whether the equipment supports UniTrust UOS, Kirin and other domestic operating systems, and whether domestic CPUs (such as Feiteng, Godson) are used.

Durability and maintenance: pay attention to MTBF (Mean Time Between Failures) ≥ 100000 hours. The shell is made of cold rolled steel or aluminum alloy, with rust proof, antimagnetic and anti-static treatment.
