Health has always been a very important topic. In today's scientific and technological era, computers are used very frequently. For most office workers, they almost always face computers during working hours, and at least eight hours a day, they face computer screens. Many people know that the long-term face of computer screens is harmful to the human body, and dealing with users who use computers frequently, Display manufacturers are also committed to researching new eye care health displays. At present, there are many mainstream eye care health displays on the market, most of which are non flashing screens and anti blue light displays. This display experience I brought is also about health, not only including non flashing screens and anti blue light functions, but also adding negative ion generators, During use, the concentration of negative ions in the environment can be continuously increased, so as to achieve better health use effect.

[What is negative ion?]

The charged particles formed after atoms or atomic clusters lose or acquire electrons are called ions. Negative ions refer to the ions with one or more negative charges, also called "anions". Some molecules can also form ions under special circumstances. For example, the ionic state of oxygen is generally anion, also called negative oxygen ion.

The positive and negative ions in the air can be divided into large, medium and small ions according to their mobility. The negative ions with small particle size have good biological activity, which can easily penetrate the blood brain barrier and enter the human body to exert their biological effects.

[Negative ion action?]

The medical care principle of negative ions is mainly because negative ions have antioxidant (reducing) properties ）Anti aging And the oxidation resistance of negative ions (Reducibility) is a basic chemical principle. Chemical reaction is the exchange of electrons on the electronic layer. The loss of electrons is called oxidation, and the gain of electrons is called reduction. The molecules (clusters) or atoms that lose electrons show positive electricity are called positive ions, and the molecules (clusters) or atoms that gain extra electrons show negative electricity are called negative ions. Therefore, negative ions with small particle size have negative potential, that is, there are redundant electrons, which can be added to the electrons of aging cells or blood cells. So as to realize the function of anti-oxidation, anti-aging and reducing free radicals. Negative ions are negative oxygen ions that obtain extra electrons. In the organism, the electron of lipid is robbed, and it will be oxidized into senile plaque; The electron of the protein is robbed, and the cell function will be abnormal; If the electrons of genes are robbed, they will get cancer In the organism, this substance that grabs electrons is called "free radical", From the perspective of quantum medicine, the seizure of electrons is the source of all diseases Similarly, iron rust, stone weathering and plant decay are all the result of oxidation. The negative oxygen ion has a negative potential, that is, there are redundant electrons. After the electrons are added to the free radicals, the free radicals are reduced to eliminate the free radicals, and they themselves become oxygen molecules O2.

Through understanding, we know that the concentration of negative ions has a great impact on health. The negative ion concentration in the rooms and offices where we often live is relatively low, which is easy to cause insomnia, headache and other problems. This is one of the reasons why many people feel obviously uncomfortable sitting in front of the computer for a long time. However, in cities where the concentration of negative ions is extremely low, negative ion products are needed to improve our environment and health. Yopai vx2415-sh is the first LCD equipped with a negative ion generator at present, which can always release negative ions when in use, thus increasing the concentration of negative ions around our environment and improving our health.

There are so many negative ions mentioned above. Now let's get to the point. As a computer monitor, negative ions are not enough. To become an eye care health monitor, its basic requirements must be met. How about the parameters such as color, response, etc?

[With its own negative ion generator, the display appearance has little impact]

As a negative ion liquid crystal display, Yopai vx2415-sh has its own negative ion generator, which is located below the front of the display and above the base. Although it looks a bit different, it is not too disharmonious in appearance. The overall black integrated design plus silver support makes the black glass base look good. As a display, do not expect it to change the negative ion concentration of the whole room, but for users in front of the computer, it is enough to increase the negative ion concentration appropriately. Especially for long-term computer users, they need a display that always releases negative ions.

The negative ion generator on the base releases certain negative ions from here to meet the demand of improving the concentration of negative ions around.

[Narrow border design, local workmanship is acceptable]

Youpai vx2415-sh adopts the design of ultra narrow frame, which reduces the volume on the premise of ensuring the display area. This is also a mainstream direction of display design today. From the figure, Youpai vx2415-sh adopts the edging design. The details are not bad, there is no obvious gap. Many of the displays with this design refer to domestic displays, which have problems such as large gap and light leakage. However, after experiencing vx2415-sh, these problems are almost invisible. The overall appearance of Youpai vx2415-sh is simple and fashionable, and it has a sense of business under the support of all black panels. It's OK to work at home.

Small arc chamfering

The base is made of glass, which is easy to clean, but it is easy to leave fingerprints. Use cloth to clean it in time.

Youpai vx2415-sh has a certain radian design on the back, taking care that the keys are on the back, so that the radian processing can just reserve a certain space for the keys. The monitor is hung on the wall so that the keys cannot be used because there is no space.

Youpai vx2415-sh interface, one HDMI interface and one VGA interface, have abandoned DVI interface, which is enough. At present, 2 Hdmi interface is basically used for the above displays.

[24 inch IPS panel, medium to high color, mainstream display effect]

Although Youpai vx2415-sh is a negative ion health display, its main function is still the display function after all. We pay more attention to the display function of the screen. In fact, Youpai vx2415-sh uses the current mainstream IPS wide view panel, showing good color restoration and transparency, especially adding eye protection methods such as non flashing screen and anti blue light, As a display integrating mainstream visual functions, eye health care, anion release and other functions, Youpai vx2415-sh performs commendably. The following is a real machine picture.

[The software test performance is good, and the panel quality control performance is good]

It can be seen from gray scale, excessive and distortion tests that the Youpai vx2415-sh performs well. As a mature technology of IPS wide view panel, it can present a good display with good quality control. In grayscale display, through eye observation, each color can be well distinguished. Of course, this is what mainstream IPS screens can do. Compared with TN screens, the IPS of Youpai vx2415-sh has more obvious advantages. The screen color is too natural, under solid color. There are no bright spots, bad spots and obvious light leaks. The solid color is also quite positive, and the degree of reduction is relatively good. The overall color of the display is not too warm or cold.

Of course, as a display with HDMI interface, it can also be directly connected to games such as PS4 for use. Youpai vx2415-sh is also a good choice to play games with PS4.

[The longer you watch TV, the more attention you need]

Of course, many people also like watching movies and TV plays. A movie lasts at least an hour and a half, and an episode lasts about 40 minutes. Most fans watch TV plays or even watch a TV play in two days. Although I personally do not approve of facing the monitor for such a long time, I have done so myself. Long term playing games, watching TV for a long time, and feeling dizzy and distended after a rest. As a health eye protection monitor, I personally think it is impossible to completely eliminate the fatigue and harm of facing computers for a long time. However, it can alleviate our bad habit. After all, the production of negative ion concentration will affect our environment and bring some health effects. Personally, it's OK to watch the computer occasionally. If you have been watching the computer for a long time, you should pay attention to your own usage habits.

[Color temperature can be adjusted and anion switch can be controlled]

The function menu of Youpai vx2415-sh is rich. Because it has its own speaker, Youpai vx2415-sh can adjust the volume, the anion switch can also adjust, and the color temperature can be adjusted. According to your preference for color, you can adjust it to cool or warm colors. The function menu is very user-friendly. At the same time, it provides options for filtering blue light, and you can control the amount of blue light according to your needs.

[Total price eye protection+anion, health monitor price is the key]

Youpai vx2415-sh does not use the direct listing sales model, but uses the crowdfunding model in JD. The price of such a special display may be higher than that of ordinary displays. After all, there is no precedent for the use of negative ion liquid crystal displays in China at present. As for the price, it is still a question. Is it acceptable or high-end?
