At present, large-size touch-control all-in-ones mainly use liquid crystal display (LCD) or plasma (PDP) display. The liquid crystal display is commonly known as LCD, which controls the liquid crystal through a circuit and cooperates with the backlight to produce a picture. Plasma display screen is abbreviated as plasma, which discharges inert gas by high-voltage electricity, and then emits light to produce a picture.
For users, the better or worse of the two has always been the most concerned issue.
Because of the different principles of light emission, the contrast, brightness, and color saturation of the plasma screen are slightly higher than those of the LCD. However, the larger the pixels of the plasma screen, the stronger the graininess of the display effect; the LCD will not have similar problems.
One of the important factors that determine the popularity of the two on the all-in-one touch controller is the power consumption, usually the power consumption of the plasma screen is more than 3 times that of the LCD. A 65-inch LED backlight LCD has an average power consumption of 220W-240W; a 63-inch plasma screen of similar size has an average power consumption of 700W. Because the power consumption is too high, in actual use, the plasma screen heats up seriously, and the user will feel a strong burning sensation when operating at close range. Because of high power consumption and high heat generation, the radiation of the plasma screen is much higher than that of the LCD.
From the perspective of product life, the life of LCD can generally reach more than 50,000 hours, which is equivalent to about 10 years. Plasma screen life is relatively shorter, the screen brightness will also decline with the use of time.
Plasma screen will appear "altitude sickness" in high altitude areas. In view of the display principle of the PDP, the plasma chamber inside the glass substrate is filled with inert gas. As the altitude increases, the external pressure decreases and the internal pressure relatively increases, especially when the internal temperature of the inert gas increases and the molecules The intense exercise will cause the pressure to rise further, thus affecting its use effect. Therefore, Panasonic and other well-known plasma screen manufacturers will clearly remind users that plasma screens cannot be used at altitudes above 2,000 meters.
In addition, plasma screens play fixed images for a long time, which will cause the problem of afterimages. Although technologies such as dynamic screensavers make up for this defect to a certain extent, they cannot be fundamentally overcome.
Because LCD has no radiation, low energy consumption, long service life and other advantages, the application rate of LCD is much higher than that of plasma screen in the application of touch one machine.
What are the functions of face powder?
1. Make up is lasting. This is its most basic function, and it is also the most recognized and familiar function, because if you do not fix makeup, it is easy to spend makeup, and will also take off makeup. With powder powder, these problems will be solved.
2. Concealer. Loose powder also has a concealer effect, which can block the defects on the face that cannot be covered by liquid foundation or air cushion. It also has the function of hiding large pores. If there are prominent pores or blackheads, it can be solved by powder dispersion.
3. Absorb oil and brighten skin. The powder has a strong adsorption effect on oil. Whether it is applied on the face or hair, it can ensure the dryness of the skin and hair, without worrying about too bright oil. And its brightening effect on skin color is obvious.
