When consumers choose a projector, they usually encounter two keywords, LCD and DLP. What are the LCD and DLP seamless splicing screen projection technologies of the projector and what are the differences? Please see below. With the development of science and technology, projection technology has gradually entered the era of digital technology from LCD technology. Nowadays, the application of projectors has spread to all walks of life and came into being. There are also various brands in the technology market. For users who want to choose products, there is only one old saying: choose only the right ones, not the ones Dear. What are the LCD and DLP seamless splicing screen projection technologies of the projector? Here, I only use my personal understanding of the two major technologies of the projector to make some comments on the adaptation direction of the two types of technical products, so as to facilitate the majority of users to consider when choosing products. Liquid crystal technology is famous for its bright colors, lifelike images, high number of colors, and rich image levels. Suitable for multimedia, film and television, advertising and other industries. The disadvantage is that the light source loss is large, and the background color of the screen cannot achieve a pure white effect; after long-term use, the LCD panel is easy to age, the color is easy to attenuate, the imaging unit is larger, and the heat dissipation requirements are high. Therefore, the appearance of the LCD technology projector is general The

Bank ATM teller machines and traditional supermarket cash registers that we see every day belong to traditional touch panels instead of touch all-in-ones. Traditional touch panels are generally single-point or double-point touch, and touch all-in-ones are actually It can realize infrared or capacitive multi-touch. We will talk about the advantages and disadvantages of infrared touch and capacitive touch and their application fields next. What is the difference between a touch all-in-one machine and an ordinary touchpad, you must know Capacitive touch screens are currently mainly used for the display of high-end devices such as mobile phones, tablets, and computers. The touch function can be realized with the skin of a human finger, multi-point, handwriting, etc. can be realized without any problem. Capacitive touch screens cannot be touched with gloves, and there is no response to touch with gloves, and the larger the size of the product required, the more expensive it is. The capacitive screen all-in-one machine is more beautiful, more beautiful, lighter and thinner, pure flat surface, and easy to realize. With waterproof function, the reaction speed is more sensitive at the same time. Infrared touch screens are currently not used for the display of high-end devices such as mobile phones, tablets, and computers. The infrared touch screen is currently only for the display.
