The display screen can be divided into three types: normal temperature, wide temperature, and ultra-wide temperature according to the supported working temperature range. The normal temperature display supports the working temperature between 0 °C and 50 °C, and the wide temperature display supports the working temperature between -20 °C and +70 °C. ℃, the ultra-wide temperature display supports the working temperature between -40℃～+90℃. Usually, the display screen with good low-temperature performance will have poor high-temperature performance. The wider the operating temperature range, the higher the price. Users can choose suitable display products according to actual use conditions.

Recently, the price rise trend of LCD is very obvious. Some original manufacturers have adjusted the ex-factory price many times, and some even adjusted the price more than 20% at one time “A panel factory recently raised its price twice in a row, each time adding 5 yuan to the original price. In fact, this kind of increase is not surprising in the industry”. The source said.   The cause and effect of this price increase   As for price increase, we are more concerned about price increase, duration and category. In fact, in this round of price increase, the rise of different LCD screens is not the same.   There are structural differences in the price increase. The main performance is that the price of low-end LCD products increased by 20% – 30% or even 40% – 50%.LTPS (low temperature polycrystalline silicon) screen and AMOLED (active matrix organic light emitting diode panel) used in high-end mobile phones have little or no price increase. At the same time, 32″ and 38.5″ LCD screens for small size TV sets have fallen below the cost price of materials, and manufacturers have been seeking price increases in recent months, while the price of 70″ or more LCD screens for large size TV sets has not fluctuated much. LCD agent Shenzhen weishixin Co., Ltd. Chairman Lu Naiming said.   According to reports, the last price rise cycle of LCD was from 2016 to 2017, and its overall market price has been falling since 2018.

The LCD screen is the most intimate part of the touch all-in-one machine and the audience, and it is also the most critical part to improve the user experience. Therefore, the quality of the LCD screen directly determines the quality and application efficacy of the touch all-in-one machine. At present, in the touch all-in-one market, the most used LCD screens are plasma, LCD, and LED. The use period is usually between 6 and 10 years. Although we can extend the use period by replacing the lamp tube, but With the lamp tube replaced, a new problem has arisen because the liquid crystal in the screen will also age. In this case, the screen display of the touch all-in-one will inevitably affect the picture quality displayed by the touch all-in-one. The touch screen is a very important part of the touch all-in-one machine. It is an inductive liquid crystal display device that can receive input signals such as contacts. The current touch screens on the market mainly include resistive touch screens, capacitive touch screens, surface acoustic wave touch screens, and infrared touch screens. Each touch screen has its own advantages and disadvantages. You must combine your own use environment and the advantages and disadvantages of the touch screen to choose a touch screen suitable for your product. As the pillar supporting the normal operation of the control integrated machine, the quality of the power supply needs to be seen in the long-term use process. You can consult the supplier about the
