Recently, Xiaobian was inexplicably allergic. He went to the dermatology department of the hospital and found that it was more lively than the morning market. In the spring, allergies seem to be the commonplace of many people. Allergic rhinitis, dermatitis, rash and other problems follow the arrival of spring, and you will be caught inadvertently. Although allergies are not a big problem, they are really upset. Xiaobian here advises friends who are allergic to allergies. Spring is here, and there must be an air purifier at home.

Can effectively remove formaldehyde, PM2.5 and other pollutants in the room. It has Sharp's unique purification particle group technology, which can release high concentration of net particles to purify the room air, and bring fresh air to the decomposition and harmless treatment of dust, pollen, mites and viruses.
Resistive Touch Screen
The outermost layer of resistance screens is usually a soft screen that connects the internal contacts up and down by pressing. The inner layer contains the oxidized metal of the physical material, namely N-type oxide semiconductor (indium oxide), also known as indium oxide, with an optical transmittance of 80% and the upper and lower layers separated by the middle. ITO is the main material used in both resistive and capacitive touch screens. Their working surface is the ITO coating. The outer layer is pressed by fingertips or any object to make the surface film concave and deformed. According to the leading line number of screen, divide again have 4 line, 5 line and much line, threshold is low, cost is opposite cheap, advantage is not affected by dust, temperature, humidity. Disadvantages are also obvious, the outer screen film is easy to scratch, can not use sharp objects to touch the surface. In general, multi-touch control is not allowed, that is, it can only support a single point. If two or more contacts are pressed at the same time, they cannot be recognized and accurate coordinates can be found. To enlarge a picture on the resistance screen, you can only click "+" several times to make the picture be enlarged step by step. This is the basic technical principle of the resistance screen.
Control by pressure induction. When a finger touches the screen, the two conductive layers are in contact at the touch point and the resistance changes. A signal is generated in both X and Y directions and transmitted to the touch screen controller. The controller detects the contact and calculates the position of (X, Y), then works according to the simulated mouse mode. Resistive touch screen is not afraid of dust, water and dirt, and can work in harsh environments. But because the outer layer of the composite film is made of plastic material, its anti-explosion property is poor, and its service life is affected to some extent.
The resistive touch screen is controlled by pressure induction. The surface layer is a layer of plastic and the bottom layer is a layer of glass, which can withstand the interference of harsh environmental factors. However, it has poor hand feel and light transmittance, so it is suitable for wearing gloves and occasions that cannot be touched directly by hand.
