The size of a touchscreen is usually measured in terms of diagonal length in inches (1 inch = 2.54cm). According to the size of the screen size, touch screen can be divided into three categories: small size, medium size and large size. Touch panels come in a variety of sizes, and different sizes are suitable for different applications due to their characteristics.
The following is a summary of common sizes and their main application areas:
1. Small size touch screen (usually less than 10 inches)
(1) 4.3 inches
Application areas: home appliances (such as microwave ovens, air conditioning control panels), industrial control (small equipment status monitoring), medical equipment (portable instruments), transportation (vehicle information interaction terminal).
Characteristics: Compact size, intuitive operation, suitable for space-sensitive and fast interaction scenarios.
(2) 5-inch / 5.7-inch
Application areas: industrial control (handheld terminals, portable equipment), medical equipment (ultrasound diagnostic instruments), car navigation systems.
Features: balancing portability and display clarity, capacitive touch technology supports multi-touch to meet the needs of complex operations.
(3) 7-inch
Applications: in-vehicle entertainment systems, smart home center control panels, e-book readers.
Characteristics: One-handed, suitable for multimedia interaction or basic equipment control in mobile scenarios.
2. Medium-sized touch screen (10-20 inches)
(1) 10.4 inches
Application areas: industrial equipment (automated production line consoles), medical instruments (operating room monitoring terminals), self-service terminals (bank ATMs).
Features: standard industrial size, mature technology, strong adaptability, meet the interaction needs of medium and large equipment.
(2) 12.1-inch
Application areas: industrial control equipment (factory automation system), interactive terminals (public information inquiry machine), medical equipment (bedside monitor).
Characteristics: moderate display area, taking into account the operating space and portability, suitable for scenes requiring efficient human-computer interaction.
(3) 15.6-inch
Application areas: retail self-service terminals (self-checkout machines), educational equipment (electronic whiteboards), commercial display screens (digital signage).
Characteristics: balancing display effect and cost, widely used in scenes requiring medium-sized visual interaction.
3. Large-size touch screen (20 inches and above)
(1) 21.5 inches -27 inches
Application areas: conference room touch one machine, teaching whiteboard, digital signage (shopping mall guide screen).
Characteristics: high resolution and wide viewing angle design, support for multi-person collaboration or remote viewing, suitable for public places of information display and interaction.
(2) 43 inches -55 inches
Application areas: commercial display (product experience screen), corporate meeting system, retail store interactive window.
Features: large touch area, enhance immersive experience, suitable for marketing scenes that need to attract eyeballs.
(3) 65-inch-86-inch
Application areas: exhibition display (corporate showroom), education and training (smart classroom), large conference room (video collaboration system).
Characteristics: large size to provide stunning visual effects, support complex gesture interaction, to meet the needs of high-end commercial or public places.
4. Ultra-large size touch screen (100 inches and above)
Application areas: digital sand table (urban planning display), immersive experience museum (science and technology museum interactive devices), large meeting rooms (holographic projection collaboration).
Characteristics: break through the traditional size limitations, combined with optical or infrared technology to achieve simultaneous operation of multiple people, suitable for scenes with high requirements for visual impact.
5. Core logic of size selection:
(1) The needs of application scenarios. Different application scenarios have different requirements for touch screen size. For example, smart phones and tablet PCs need portable touch screens, so the size is relatively small; while touch screen TVs and industrial touch screen computers need a larger display area to show complex information and operation interfaces.
(2) Users' operating habits and needs. Different users have different needs for touch screen size. For example, some users may prefer a larger touch screen to better view and operate the content; while others may focus more on the portability of the device and prefer a smaller touch screen.
(3) Cost and budget considerations. Touchscreens of different sizes vary in cost. Therefore, when choosing the size of the touch screen, you need to consider the application scenario, user needs and cost budget and other factors.
