A touch all-in-one computer is a device that combines a touch screen, an LCD screen, an industrial PC unit, and an all-in-one computer housing, and can be operated by touch with just one power cord.
When purchasing a touch all-in-one computer, you need to consider factors such as size, price, function, touch performance, health impact, and heat dissipation performance.
Size has a greater impact on price. For example, the price range of a 55-inch computer is about 5,000-7,000 yuan, a 65-inch computer is 10,000-13,000 yuan, a 75-inch computer is 20,000-23,000 yuan, and a 98-inch computer may cost as much as 120,000-150,000 yuan.
In terms of function, a touch all-in-one computer is not just a computer with good performance. It can also connect various peripherals to achieve diversified functions. An all-in-one computer that supports multi-touch technology can provide a better control experience and higher playability.
While paying attention to touch performance, health and heat dissipation issues must also be considered. When operating a touch-screen all-in-one, the user is close to the screen, so choosing a display with good display effect and low radiation is crucial to protecting the user's health.
In long-term use, good heat dissipation performance is the key to ensuring stable operation of the equipment, and it can also effectively avoid the problem of dry skin caused by increased screen temperature. In terms of technical application, the LCD screen is the part of the touch-screen all-in-one that is most closely in contact with the user, which is crucial to improving the user experience.
Currently, the main LCD screens on the market are plasma, LCD, and LED, and their service life is usually 6 to 10 years. Users can check the quality of the LCD panel through specific software. Although replacing the lamp can extend the service life, the problem of LCD aging is still inevitable. As a key component of the touch-screen all-in-one, the performance of the touch screen directly affects the user experience.
Currently, the touch screen technologies on the market mainly include resistive, capacitive, surface acoustic wave, and infrared. Resistive touch screens have a fast response speed but low accuracy; capacitive touch screens are sensitive to operation and suitable for multi-touch; surface acoustic wave touch screens are suitable for harsh environments; infrared touch screens are easy to install and suitable for large-size screens. According to the use environment and needs, users should choose the most suitable touch screen type.
The host configuration is the basis of the quality of the touch-screen all-in-one, including CPU, chip, memory, hard disk and industrial control motherboard.
The screen material should also be considered when purchasing a touch-screen all-in-one. When choosing an LCD screen, key indicators such as color performance, viewing angle range, and response time should be considered.
In addition, the brightness and contrast of the screen are also important considerations. The higher the brightness, the clearer it is in a bright environment, while the high contrast can provide richer colors and better details.
When purchasing a touch-screen all-in-one, you should consider the size, price, function, touch performance, health impact, heat dissipation performance, touch screen technology, host configuration, power quality, decoding function, screen material and other aspects to ensure that the final device can not only meet the use needs, but also have a good operating experience and long-term stability.
