What are the types of mobile phone LCD screen interfaces for Hechengsheng 3C accessories?

The interface is generally 30pin, and the 19-wide and 22-wide interface lines can be used universally.

For example, inch widescreen, but due to different sizes and resolutions, most of the LCD interfaces are LVDS

There are also RSDS interfaces: 9 or 16, the number of pins used is not the same, and the size of the width needs to look at the specifications of the LCD screen: 10 wide screen, 17 wide, depending on the definition of each pin, but it is relatively rare.

Only 15 interface screen cables are needed; 19-inch widescreen, 27 strips are required. Generally speaking, the type of mobile phone LCD screen interface.

Now universal 16

MIPI is the most common interface for mobile phone LCD screens.

Nowadays, the common 16:9 or 16:10 widescreen, most of the LCD interfaces are LVDS, and there are also RSDS interfaces, but there are relatively few.

The interface is generally 30pin, but due to different sizes and resolutions, the number of pins used is also different. For example, for an inch wide screen, only 15 interface screen lines are needed; 19-inch widescreen, 27 strips are required. Generally speaking, 19 wide and 22 wide interface cables can be universal, and 17 wide, wide and other sizes need to look at the specifications of the LCD screen to see the definition of each pin.

In addition, because of the different solutions and designs adopted by each different LCD manufacturer, the same cable cannot be used on different brands of displays.

、What material is used to make the LCD screen of the above mobile phone? The LCD screen of the mobile phone is composed of: upper polarizer, upper glass, liquid crystal lower glass, lower polarizer, etc.

There are the following:

1. Lithium-ion battery.

It is a kind of battery with lithium metal or lithium alloy as the anode material and non-aqueous electrolyte solution;

2. Lithium-ion polymer battery.

It is a kind of lithium-ion battery, which is composed of positive electrode, negative electrode, electrolyte, separator, aluminum-plastic film, and other components; The materials used are: cathode: aluminum foil, lithium cobalt oxide, lithium nickel cobalt manganese oxide, lithium iron phosphate, PVDF, conductive agent, etc.;

3. Travel charger.

A static converter device that converts the constant voltage and frequency of alternating current into direct current by using power electronic semiconductor components;

4. Mobile phone LCD screen.

There are several types of TFT, TFD, UFB, STN and OLED. Generally speaking, the more colors that can be displayed, the more complex images can be displayed, and the more layers of the picture will be.

The quality is actually okay, as long as it is used normally, there will generally be no problems!

If you want to know what quality is, you have to learn how to distinguish it

1. Look at the size of the mobile phone screen: In other aspects, the larger the screen, the clearer you can see, and the better it is for your eyes.

2. Look at the resolution of the screen: the common screen resolution is 320x480; 480x800；960x540；960x640。Generally speaking, it is good to reach the "retina screen", such as inches need a resolution of 960 640; The larger the screen, the smaller the resolution you need.

3. Look at the mobile phone screen material: the materials are IPS, TFT and OLED, and now better mobile phones generally use ISP and OLED, ISP has a large viewing angle, better contrast, and good dynamic picture definition.

4. Look at the screen color: At present, there are 256 colors, 4096 colors, and 65536 colors for color screen mobile phones, and good mobile phones are as high as 16 million colors.

5. Is the touch screen of the mobile phone a capacitive screen or a resistive screen: the touch sensitivity of the capacitive screen is good, the precision is high, it can be touched at multiple points, it is cleaner and cleaner, and the visual effect is much better under the sun.

Now it has generally reached a capacity of 3000mAh, and the ordinary one has reached a capacity of 2500mAh-3000mAh, and the battery is not as big as possible, it is still necessary to control the volume and weight, and the largest battery is currently 5000mAh.

Yes, as long as it is an electronic product, it must pass the 3C certification!

1.Turn on the power of the charger first, the charging indicator light is on (red), and the color is red to charge normally.

2.Put on the battery and charge it in constant-current mode (constant current) at 500mA.

3.About 1 hour and 50 minutes full indicator light is on (green), which is shown as green not fully full, but only represents the end of the constant current charging phase.

4.At this time, it is not fully charged, but charged in constant-voltage mode (constant voltage), which can be charged for 10 to 20 minutes. Namely:

The battery can be removed 20 minutes after the green light is on. Note: When the battery voltage is lower, this charger will enter trickle-charge mode, at this time, it will charge at 50mA until the voltage is greater than entering constant-current mode, and there is no current output without discharging the battery, so this charger has a safety mechanism.

It's not bad, last year's Double 11 was bought by myself and my girlfriend, we both bought a travel charger, used it for a year, basically there was no problem, and the charging voltage of this travel charger is a standard 5V, charging***, safety is also good, there is not much impact on the life of the mobile phone battery!

Well, I used it before the manuscript was blind, and it has the following characteristics:

1. Smart charging.

2. Small and convenient.

3. The whole air surface is compatible.

4. Practical and safe, easy to carry in travel.

Compared with others, it is better, intelligent charging, easy to carry, fully compatible, practical and safe, and easy to carry in travel.
