1. Patch
Namely surface mounting technology, which is a more traditional installation method. The advantage is high reliability, but the disadvantage is large size and high cost, which limits the miniaturization of LCM.lcd module，
Two, COB
That is, the chip is attached to the PCB, because the IC manufacturer is in LCD control and related.
Three, TAB
Packaging (Tape Carrier Package) IC is fixed on LCD and PCB with anisotropic conductive adhesive. This installation method can reduce the weight, volume, installation convenience and reliability of the LCM!
Four, COG Chip On Glass
The chip is directly bonded to the glass. This installation method can greatly reduce the volume of the entire LCD module, and is easy to mass produce, and is suitable for LCDs used in consumer electronic products.
Five, COF
The chip is directly mounted on the flexible PCB. This connection method is highly integrated, and peripheral components can be mounted on the flexible PCB together with the IC. This is an emerging technology entering the trial production stage.

1. Minimize the possibility of direct exposure of the screen to strong light to prevent the screen from being irradiated by strong light, resulting in excessively high temperature and accelerated aging;
2. The LCD screen is one of the most vulnerable parts.3.5 inch lcd display， It is best not to point to the screen with sharp objects such as pens and keys;
3. Keep the voltage and power supply normal;
4. When using, be sure to avoid long-time booting and work, let alone display the same screen for a long time, so that it is easier to accelerate the aging of the LCD screen and promote the formation of dead pixels.

Common hard wired earphones may be split into three classes: shifting steel earbuds, transferring coil earphones, Wired Headphones，and engagement ring metal headphones.
1. Transferring metal earbuds:
It is a little confined place and can be simply motivated with just a little current. The device is very tiny, so it can reach numerous devices for example three units and four devices inside the headset. The advantages are substantial audio quality solution, rich information, and powerful expressiveness. The problem is the fact that it could be a tad high-priced.
2. Powerful earbuds:
It is currently the far more everyday sort of head set. It relies on a shifting coil to make a noise. The advantage is its sound is near natural, the reduced volume is relatively whole and wide open, and also the cost is going to be less costly. The problem is the fact that sound is lacking in specifics and environment.
3. Engagement ring steel earphone:
As the brand indicates, this is a mix of moving coil and shifting metal. The benefit is that it combines some great benefits of another two headsets, as well as the sound quality is very good. The downside is that the relationship is not really great, and you will discover a crystal clear divorce involving the moving iron as well as the transferring coil.

Put water and baking soda together. The alkaline component of baking soda is very suitable for decomposing the acid residue around the zoom lens and restoring the quality of the camera lens. buy prescription sunglasses online ，The viscous mixture of baked soft drinks and water can remove scratches and thoroughly clean the lenses.
Mix one-component drinking water and two-component soft drinks in a small container. The amount of water and soda mainly depends on the size and quantity of the mark. You can start with one tablespoon of water and 2 tablespoons of soda water. If the signs of wear are severe, you can increase the total amount.
Mix ordinary water and prepare soft drinks. Keep mixing until the mixture becomes a thick mixture. Do not put excessive drinking water. When the prepared soda cream is too thin, the effect of removing marks may be greatly reduced.
Go for a cotton ball. Partially put the cotton tennis ball in the soda mixture. You only need to use a pea-sized soda mixture to eliminate all damage.
Mix soda water on the scratches. Use a pure cotton football to massage the wear marks on the lens in a circular motion. The kneading time is about 10 minutes. This will help remove scratches.
Use a smooth, lint-free material to clean the lens. The function of this towel is very important, because it can ensure that the lens will not be scratched again during the washing process. You can get a pack of microfiber glasses fabric through visual shopping. If there is residual baking soda mixture in the zoom lens, please use the material to wipe it clean.

The damage of ultraviolet rays to the human body is cumulative. The longer the exposure to the sun, the greater the damage of ultraviolet rays. There is a statistical report in the United States that 80% of the ultraviolet rays that a person is exposed to in his lifetime are accumulated by exposure to sunlight before the age of eighteen.style of sunglasses
Therefore, to avoid the damage of ultraviolet rays, one must start from a young age.
To avoid damage to the eyes caused by ultraviolet rays, it is of course necessary to minimize exposure to strong sunlight, especially between 10 am and 2 pm, when the sun is directly on the surface of the earth and the ultraviolet intensity is the highest. Especially those ultraviolet rays reflected from cement, snow, beach or water are the most powerful and cause the most damage to the eyes, but they are the easiest to be ignored.

Note: It is best to confirm that the lens can effectively block more than 99% of ultraviolet rays (including ultraviolet A and ultraviolet B), and at the same time have polarizing characteristics.
Sunglasses are not only required to be worn in summer, in fact they must be used throughout the year. Wear it on sunny days and also on cloudy days. Don't think that the sun is not strong on cloudy days and the weather is not hot. Just take it lightly and unknowingly expose it to more harmful ultraviolet rays.

The poor stuffing cotton is black cotton, which feels bad and is very dirty.
Whether the fixed parts are firm (the standard requirement is 90N force) is very irritating, whether the moving parts are too small to prevent children from accidentally entering the mouth while playing, and whether the raw materials of the same color or the same position have the same hair direction, otherwise it will The color is different under the sun, and the hair direction is opposite, which affects the appearance.
Check the inner and outer packaging, whether the signs are consistent, and whether the moisture-proof performance is good. If the inner packaging is a plastic bag, and the opening size exceeds a certain range, there must be vents to prevent children from suffocating the head by mistake.

As we all know, new mattresses will have a little peculiar smell when they are purchased. Especially for those who are more sensitive to smell, ultra plush mattress, it is even more intolerable. So do you know how to quickly eliminate the odor of a new mattress?
1. Ventilation and deodorization method.
Generally, you can remove the plastic protective film from the outer layer of the mattress and place it outside for ventilation. This method is suitable for the situation where the smell of the mattress is not very pungent. During the mattress manufacturing process, the smell of the processing technology is normal. It only needs to be stored for about a month before the smell will disappear naturally.
2. Bamboo charcoal adsorption method.
Many families choose bamboo charcoal to absorb mattress odor. Bamboo charcoal has a super adsorption capacity and the function of radiating far infrared rays. It can absorb moisture, peculiar smell and harmful gases, and keep the indoor air fresh and the bed dry.
3. Activated carbon adsorption method.
Placing activated carbon indoors to absorb mattress odor and formaldehyde is also a more reliable method. Activated carbon has a relatively strong physical adsorption capacity, and the peculiar smell of the mattress will be reduced after a period of time.
4. Deodorizing method of grapefruit peel.
Put the pomelo peel on the head of the bed, about a week or so, the smell of the mattress will slowly fade away, leaving a faint fragrance. Similarly, pineapple and tea can also play a role in adsorbing peculiar smell.
