First, the lighting principle of AMOLED screen is different from that of LCD screen. LCD screen is made up of lighting template, which is composed of lamp beads. In theory, the more lamp beads, the higher the brightness. AMOLED is pixel self luminous, which means the brightness is not as bright as LCD.

Simple understanding of the difference between AMOLED screen and LCD screen

AMOLED is pixel self luminous.
this means that the brightness is not as good as that of LCD.
the brightness of AMOLED is lower than that of LCDSecondly,
because AMOLED is pixel self luminous, it does not emit light at all when displaying black, which can save power to a certain extent.
and because of the characteristics of pixel self luminous, the AMOLED screen will not have light leakage.
the reason for the light leakage phenomenon is that the backlight template of LCD screen is not packaged properly.
the backlight template of LCD screen is not packaged properlyThe third problem is the thickness.
AMOLED screen has no backlight template, so the thickness is lower than LCD screen, which means that mobile phones can be thinner and the screen shape can be changed. For example, Samsung's curved screen is actually AMOLED screen.
without backlight module, the screen can be made into a flexible screen.
the thickness of the screen is lower than that of the LCD screenThe main disadvantages of AMOLED screen are as follows.
the main disadvantages of AMOLED screen are as followsFirst, the brightness is not as good as that of LCD.
LCD screen can achieve the purpose of improving brightness by adding lamp beads, but if the brightness of AMOLED is too high, there is a risk of screen burning.
the brightness of AMOLED is too highSecond, due to the special pixel arrangement of AMOLED screen,
the display effect is only three-quarters of that of LCD screen. In the case of the same resolution,

LCD is the abbreviation of liquid crystal display.
the structure of LCD is to place liquid crystal in two pieces of parallel glass, and there are many vertical and horizontal small wires between the two pieces of glass, The direction of the rod crystal molecules can be controlled by electrifying or not,Light emitting diode (LED) is a kind of semiconductor solid-state light-emitting device, which uses solid-state semiconductor chips as light-emitting materials. When the positive voltage is applied at both ends, the carriers in the semiconductors will compound, causing photon emission and producing light.
LED can directly emit red, yellow, blue, blue, white light Green, green, orange, purple and white light.
principle and characteristics of LED: LED (light emitting diode).
is a semiconducting solid-state light-emitting device.
it uses solid-state semiconductor chips as light-emitting materials.
when the positive voltage is applied at both ends.
it directly emits red, yellow, green, green, orange, purple, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green, green White light.
changeable and illusory: LED light source can make use of the principle of LED short time and red, green and blue three primary colors.
under the control of computer technology, it can realize multiple changes of color and pattern, and is a kind of "dynamic light source" that can be controlled at will.
long life: LED light source has no filament and low working voltage.
its service life can reach 50000 to 100000 hours, That is 5 years to 10 years.
environmental protection: no harmful elements in production, no harmful substances in use, no radiation.
High Tech Tip: compared with traditional light source.
LED light source integrates computer, network, embedded and other high-tech, with the characteristics of online programming, unlimited upgrade and flexibility.
