In terms of display effect, the advantages of OLED screens are too attractive compared to LCD screens. The OLED screen has the function of individually controlling the pixels. In daily use, not every scene needs to light up all the pixels of the screen. Therefore, it can display a more pure black effect, and can also achieve 1000000:1 in terms of contrast ratio, so that the bright places are bright enough, and the dark places are very dark, bringing a more realistic display effect. 0.96Inch Oled,0.96Inch Oled Display,OLED screens,Lcd Panel Oled Display Shenzhen Newvision Technology Co.Ltd , https://www.newvisionlcd.com
1. Select the measurement range
As with measuring weight and temperature, the humidity sensor is selected first to determine the measurement range. In addition to meteorological and scientific research departments, temperature and humidity measurement and control generally do not require full wet range (0-100% RH) measurement.
2. Select measurement accuracy
Measurement accuracy is the most important indicator of the humidity sensor. For every percentage point increase, it is the last step for the humidity sensor, or even the previous level. Because of the different precisions, the manufacturing costs vary widely, and the selling price is far from the same. Therefore, the user must tailor the clothes, and should not blindly pursue "high, fine, sharp".
If the humidity sensor is used at different temperatures, the indication will also take into account the effects of temperature drift. It is well known that relative humidity is a function of temperature, which severely affects the relative humidity within a given space. The temperature changes by 0.1 °C. A humidity change (error) of 0.5% RH will be produced. In the case of use, if it is difficult to achieve constant temperature, it is not appropriate to propose excessive humidity measurement accuracy.
In most cases, the accuracy of ±5% RH is sufficient if there is no precise temperature control or if the space being tested is unsealed. For areas requiring precise control of constant temperature and constant humidity, or where it is necessary to track and record humidity changes at any time, select a humidity sensor with an accuracy of ±3% RH or higher.
The requirement that the accuracy is higher than ±2% RH may be difficult to achieve even the standard humidity generator of the calibration sensor, not to mention the sensor itself. Relative humidity measuring instruments, even at 20-25 ° C, to achieve 2% RH accuracy is still very difficult. The characteristics given in the general product data are measured at room temperature (20 ° C ± 10 ° C) and clean gas.
In addition, compared with LCD screens, OLED screens have removed components such as backlights and polarizers. In terms of sliding and touch, OLED screens can provide a touch response speed of 0.2ms, and dynamic content such as content sliding and games. In the scene, the OLED screen can provide a clearer look and feel.
It is precisely because of this that more and more notebook manufacturers are beginning to deploy and promote OLED screens on their own products to further improve the display effect of their own products. Among the notebook computer manufacturers, ASUS is the most active. The slogan of #ASUSscreen# has been played before, and with the help of high-quality OLED screens, it brings a more amazing display effect than LCD. The recently launched new product, the ASUS Unparalleled series, has brought the 120Hz high-brush OLED screen to the 5K price range, reducing the dimension of products at the same price.
What should I pay attention to when using the humidity sensor?
Human survival and social activities are closely related to humidity. With the realization of modernization, it is difficult to find a field that has nothing to do with humidity. Due to different application fields, the technical requirements for humidity sensors are also different. So what should you pay attention to when choosing a humidity sensor?
