LED display backlight meter is generally greater than 12V, according to different display settings. You can try the following methods:
The backlight of LED display is generally greater than 12V, which can be detected according to different display settings.
the following methods can be tried:
1
2. Adjust the power supply voltage from 12V to gradually increase<

What is the backlight voltage of LED display

3. Until the LED light is on.
the voltage range can be determined.

4. Some led voltages may be above 30V.
pay attention to the operation safety.






extended data:  <

display is also called monitor.
display is an I / O device of computer.
it is a display tool that displays certain electronic files on the screen through a specific transmission device and then reflects them to the human eye.

according to the different manufacturing materials, it can be divided into cathode ray tube display (CRT), cathode ray tube display (CRT), cathode ray tube display (CRT), cathode ray tube display (CRT), cathode ray tube display (CRT), cathode ray tube display (CRT), Plasma display panel (PDP), liquid crystal display (LCD) and so on.

working principle
liquid crystal is liquid crystal.
it is a very special substance.
it can flow like liquid.
it also has some optical properties of crystal.
liquid crystal was discovered by Austrian botanist reinitzer in 1888.
it is between solid and liquid, Organic compounds with regular molecular arrangement.

the arrangement of liquid crystal molecules has a certain order.
and this order is very sensitive to the changes of external conditions, such as temperature and electromagnetic field.
under the action of electric field.
the arrangement of liquid crystal molecules will change, thus affecting its optical properties, which is called electro-optic effect.
this phenomenon is called electro-optic effect
Led
LED panel: LED is the abbreviation of light emitting diode.
it is a display mode by controlling semiconductor LED.
it is used to display text, graphics, images, animation, market, video, etc Source: Baidu Encyclopedia - displays are all 12V.
n   It has a photosensitive control system.
it can automatically adjust the brightness of the display screen according to the change of the brightness of the outdoor environment, saving energy and protecting the environment, greatly reducing your operating cost; It can also make the audience more receptive.

n   It has high refresh rate and high gray level.
it makes the picture of LED display more realistic and meets the requirements of high visual quality for commercial use.

n   It has the function of brightness.
color point by point correction, which makes the LED display screen richer and meets the requirements of high visual quality for commercial use.

n   The advertising content on the advertising LED display screen can be changed at any time.
display different advertisements for different customers all day long.

n   It has dual network line hot backup function.
two computers control one screen at the same time. When one computer has problems, the other computer will take over automatically to ensure the normal work of the screen.

n   An efficient optical fiber transmission system is adopted.
the phenomenon of signal delay caused by long transmission distance is effectively reduced, and the consistency of picture playback is ensured.

n   All the display information can be controlled by remote network.
the screen information can be easily changed with the mouse click operation, so as to realize the clustering of advertising display network in cities and regions.
in this way, the display information can be easily changed
n   Support network control function.
enables you to control the display screen of several cities in one place and change the content you want to play at any time.

n   With our multi-function card.
it can be turned on and off at any time by software or manually to realize the unattended function.

n   The screen is equipped with an environmental monitoring system.
to let you know the operation of the display screen anytime and anywhere.

n   Not only mounting bracket is provided.
a complete set of LED is also provided   Display system, including control system, power supply (socket), software, accessories, installation structure drawings and other services   The standardization of box design makes the same box size suitable for different pixel display requirements, and makes the installation of LED advertising screen more convenient.

n   The LED box is thinner and lighter, saving transportation cost.

n   Good waterproof effect.
with IP65 protection grade, it is suitable for outdoor use.

n   The LED display screen has built-in lightning protection device.
to prevent the display screen from burning down due to lightning stroke.

n   The LED video control system has a dual backup system.
in case of failure, customers can switch to the backup system immediately.

n   The company also provides relevant maintenance spare parts for customers.
all spare parts are modular design, which is convenient for after-sales maintenance.

n   According to customer requirements and site environment.
tailor the most suitable LED display solution.
