Comparison and analysis of the functional characteristics of the touch all-in-one machine and the projector:
One, performance
Touch all-in-one machine is a perfect combination of touch screen, LCD screen, industrial PC unit (commonly known as the host) and all-in-one shell, and finally touch operation can be realized through a power cord. The touch all-in-one machine is equipped with the world's most advanced multi-point infrared touch screen. There is no delay in touch and the response is sensitive. All controls are completed on the screen surface. Any object touch, including fingers and pens on the touch screen, controls all applications, and easily realizes handwriting, Functions such as drawing and refilling are smooth, stable and reliable in use. The biggest advantage of the touch all-in-one is that it has all the functions of a computer TV. The projector has to be connected to a computer, which looks cumbersome and troublesome to operate.
2. Response speed
The touch all-in-one machine is highly integrated, integrated PC, projection system, screen, display system, audio, and multi-touch in one; high-definition display, clear images, no glaring problems of front projection light; not affected by external light sources, simple installation , Built-in computer; high-definition multimedia interface with HDMI. In terms of response speed, the touch all-in-one machine also has an advantage, which can reach 5ms to respond quickly. However, the traditional projector equipment will be calculated in seconds, and it will be very stuck during a meeting, which is inefficient for education or corporate meetings.
Three, clarity
Projectors are all controlled by the connection of a computer, and because the projected screen is usually a curtain, when the picture on the computer is enlarged, it will not be very clear! At least the visual effect is a bit far from what you see on the computer, and sometimes the color difference is large. The touch all-in-one is a computer and a monitor, and generally uses an industrial-grade LCD A screen, the control is relatively simple, more intuitive, and its fidelity is high! It is more demanding than the high-definition LCD TVs we usually watch, so the touch all-in-one is more high-definition and full of colors.
