Capacitive screen: capacitive screen is operated by electrostatic induction, that is to say, the screen feels the static electricity of your fingers, and then accepts the operation. Sensitive touch, no need to press the screen, support multi-point touch, but can only touch with fingers, the relative accuracy is not very high.

it is sensitive to touch.
it does not need to press the screen, and supports multi touch, but it can only be touched by your fingers, and the relative accuracy is not very high.

generally speaking,
resistive screen can achieve more accurate positioning, You can operate with your fingers or a stylus; However, the capacitive screen can only be operated by fingers with static electricity, and the pen is not available. If the person is over, the fingers will not be used, ha ha.
(of course.
there are also special pens for capacitive screen, But it's not very easy to use).
the difference between the two is that the capacitive screen doesn't use a stylus, but uses a finger to touch the screen (now there are special stylus suitable for capacitive screen).
while the resistive screen needs a stylus or other sharp objects to complete the operation.
for example, after you get your mobile phone.
touch the screen with your nails or hard objects, as long as you can operate it, that is the resistive screen, On the contrary, it is capacitive screen.
in the sun, the visual effect of capacitive screen is better than that of resistive screen.
capacitive touch screen is easy to realize multi touch function (key point).
resistive screen is point touch.
often with touch pen, low sensitivity, capacitive screen is face touch.

LED is light emitting diode.

simply speaking, it is screen based on light emitting diode.
can not touch screen, When you press it, it doesn't respond.

LCD is the abbreviation of liquid crystal display.
the difference between LED and LCD is not very big.
the difference between LED and LCD only lies in the backlight.
the panel is the same.
the business said so.
the business said thatIt's a bit deceptive.
the real LED is like the big billboard we see on the wall.
the panels of both of them are liquid crystal.
also called TN panel.
backlight type.
LED and CCFL are diodes and cold cathode lamps, respectively. You can find them when you search Baidu.
of course, diodes are better.
energy saving, environmental protection, small space, high brightness, Fashion.
but the price is more expensive.
if you are optimistic that the two prices are similar.
you still buy led, if the difference is too much, you need LCD.
.
the LED of LED backlight LCD TV, which is popular in the market, is only used as backlight.
strictly speaking, it is not led display. Small and high-resolution video LED displays are all using OLED. OLED has self illumination, wide viewing angle, high-resolution and high-resolution With the advantages of high contrast, low power consumption and high reaction rate, OLED display can be made thinner than LCD display because it does not need backlight. However, the life of OLED display is only one fourth of that of LCD display. Toshiba and Panasonic in Japan have new technologies in recent years to double the life of OLED.
.
capacitive screen.
when fingers touch the screen, The capacitance changes between the finger and the screen to sense the position.
resistive screen.
pressing the finger causes the screen to deform, and the internal resistance changes to determine the position.
therefore, the resistive screen must contact the screen surface.
capacitive screen can be sensed as long as it is close to the screen surface.

LED is a light emitting diode.
there is a large outdoor advertising screen, and the LED dot matrix display is used.
