LCD is the abbreviation of liquid crystal display, which uses liquid crystal to adjust the polarization direction of light to realize the display of images. With the continuous development of technology, LCD is also constantly upgraded and improved, especially with the addition of touch screen technology to meet the user's more convenient and fast control needs. The following is related to touch screen operation and LCD display related aspects.

 

First of all, the display principle of the liquid crystal display is to deflect the cross-section of the internal LCD material through the adjustment of the voltage of the liquid crystal layer, so as to achieve the effect of controlling the light transmission of the pixels and forming an image. Therefore, the intervention of the touch screen principle will not basically affect the LCD display effect. At the same time, the touch screen operation also adopts more advanced technology, which is realized by multi-layer coating, which has the advantages of shading, wear resistance, and anti-pollution. However, it should be noted that the touch screen operation also requires a very fast click response time, because the refresh rate of the liquid crystal display is very fast. If the response time is too long, errors will occur, which in turn will affect the user experience.

 

Secondly, for the touch screen operation of the liquid crystal display, the first thing to pay attention to is the technology selected by the touch screen, because there are currently many technologies such as capacitive, resistive, and image pressure-sensitive. Among them, the capacitive touch screen has the best operation effect, but the premise is that the capacitive screen must be grounded and subject to various interference problems such as moisture and static electricity. Therefore, users need to pay attention to maintenance and avoid contact with conductive objects such as metal. Resistive touch screens have also become popular, and an external object is pressed against the touch screen when touching, so that electricity is energized between two electrodes, thereby realizing operation. This technology is relatively popular and low in cost, but it requires high pressure and does not support multi-touch, so it has certain limitations. In addition, image pressure-sensing technology is also a very good choice. It can track fingers sliding up and down, left and right, and realize multi-touch at the same time. This is also the main way to use laptops and tablets.

 

Finally, in the selection of liquid crystal display and touch screen operation, it is also necessary to consider different needs and applications, including processing speed, transmission speed, definition, contrast and other factors. Safe, reliable and durable. Therefore, merchants and users need to fully understand relevant knowledge and technologies when purchasing LCD monitors or using touch screen operations, so as to avoid wasting time and money due to wrong choices.
