    Biyografi: Due to the increasing use of electronic products, there are

    many electronic products used outdoors. How to choose a high-

    brightness LCD panel, the article content will give you a few

    points on how to choose a high brightness LCD panel.

    What are the special requirements for


    lcd/]high brightness LCD[/url] panel?

    1. The brightness should be high, visible in the case of

    direct sunlight, the brightness of the high brightness LCD

    should be 1000-3000nit.

    2. High temperature and low temperature resistance; high

    brightness LCD panel operating temperature should be -30℃ to


    3. The anti-drop performance should be reliable; the high-

    brightness LCD panel should be able to meet the drop test.

    4. The product perspective should be large, the display

    should reach 89 above the full viewing angle

    Does high brightness of LCD panel lead to high power


    The brightness of the high brightness LCD panel is

    determined by the brightness of the backlight. There are many

    ways to increase the brightness of the backlight, Classified by

    whether increasing power consumption:

    1. Directly increase the power consumption to increase the

    brightness of the highlighted LCD screen.

    increase the number of LED lights,

    increase the current of the LED lamp.

    The advantage is to increase the brightness directly.

    The disadvantage is that the power consumption is increased

    and the heat generation is increased.

    2. A conventional design that does not increase power

    consumption but can increase brightness.

    Use a film with higher optical effects, such as high

    brightness, high transparency, high reflectivity

    LED light with large chip can increase brightness under the

    same power consumption

    The advantage is that the brightness can be further

    improved, and the cost performance is higher, and the power

    consumption is increased by zero.

    The downside is that costs are rising significantly.

    The Importance of High Brightness LCD Displays For A Range

    of Industries

    Liquid-crystal display, or better known as LCD, is a

    flat-panel display technology that primarily uses liquid

    crystals. Although liquid crystals do not directly emit light,

    experts use reflectors or backlights to produce colorful or

    monochromatic images.

    Think of these liquid crystals and their light-

    modulating properties being sandwiched between thin glasses. A

    diversely wide range of applications benefits from LCD

    technology. Commonly known applications are televisions,

    smartphones, computer monitors, cockpit displays, digital

    signage, and touch screen displays. It is also applied to other

    electronic [url=http://www.risingstarlcd.com/]products[/url]

    such as DVD players, clocks, and video game devices.

    Advancements in industrial touch screen flat-panel

    liquid-crystal displays

    In nearly all fields and applications, LCD has replaced

    the older, bulkier display technology that is known as cathode

    ray tube or CRT. LCD offers more screen size options, which

    makes its flexibility more appealing to both consumer and

    provider. An LCD screen is thin and light and requires lower

    power consumption than a CRT display.

    A [url=http://www.risingstarlcd.com/lcd-

    display/industrial-high-brightness-lcd-display/]industrial high

    brightness LCD display[/url] can consume much lesser than a

    heavy CRT display screen. Due to its low power consumption,

    there is little heat emitted while it is used. LCD screens also

    display sharper images that cannot be smeared using a native

    resolution. It also has a masking effect – an LCD grid can

    create an illusion of higher image qualities. Compared again to

    a CRT display, the LCD is preferable as it emits almost no

    electromagnetic radiation.

    The Industries That Benefit from LCD High Brightness


    Many people may think that tech industries utilize LCD

    technology more than any other public or private field/sector.

    That is true to an extent. However, it is also a fact that

    people nowadays depend on the efficient and affordable

    technologies constantly developed in the modern age; thus, any

    institution or organization also depending on commercial

    investments or services would normally need the advantages

    offered by LCD.

    LCD high brightness monitors are inexpensive, making

    them a viable option for companies that manufacture smartphones

    and other electric or handheld gadgets. In the world of

    advertising, commercial services may make use of LED screens

    since they are better for large-scale outdoor displays. On the

    other hand, some companies may use LCDs if they want to provide

    displays for enclosed spaces.

    LCD touchscreen technology versus LED

    Although LCD and LED are significantly different, LCD

    is more commonly used in touchscreen technology. LEDs emit more

    light naturally, but a high brightness

    [url=http://www.risingstarlcd.com/lcd-display/]LCD display

    [/url] can still attract the attention of the viewer. Video

    display-developing businesses utilize LCDs more than commercial

    businesses in a way that they utilize the technology to develop

    laptops, desktops, and all-in-one touchscreen computers.

    Laptops have a growing demand because of its own capabilities

    and advantages, and several laptop brands have already started

    to conduct other technological integration into LCD.

    What is the impact of high working temperature on the LCD

    strip screen?

    1. Too high temperature will cause devastating damage to

    the LCD strip screen

    (1)LCD displays are usually packaged with silicone. If

    the working temperature exceeds the solid phase transition

    temperature (typically 125 °C), the packaging material will

    become a rubber state and rapidly heat and expand, resulting in

    an open circuit and failure of the LCD bar screen.

    (2)If the operating temperature of the


    display/]strip LCD display[/url] exceeds the maximum load-

    bearing temperature of the chip, its luminous rate will drop

    rapidly, resulting in light attenuation. The life of an LCD

    screen is reflected by the attenuation of light, that is to

    say, the brightness of the LCD screen will decrease over time.

    2. The reason why temperature affects the luminous rate of

    the LCD bar screen:

    (1)As the temperature increases, the concentration of

    electrons and holes increases, the band gap decreases, and the

    electron mobility decreases.

    (2)High temperature will shift the blue peak of the chip

    to the long-wave direction, causing the chip's wavelength

    to not match the phosphor's wavelength, thereby reducing

    the light extraction efficiency outside the liquid crystal


    (3)As the temperature increases, the quantum efficiency

    of the phosphor decreases, the luminescence decreases, and the

    light extraction of the liquid crystal display decreases,

    resulting in a decrease in the brightness of the liquid crystal


    Since both LED and LCD TVs are based around LCD technology,

    the question remains: what is the difference? Actually, it’s

    about what the difference was. Older LCD TVs used


    cold cathode fluorescent lamps (CCFLs)[/url] to provide

    lighting, whereas LED LCD TVs used an array of smaller, more

    efficient light-emitting diodes (LEDs) to illuminate the


    Since the technology is better, all LCD TVs now use LED

    lights and are colloquially considered LED TVs. For those

    interested, we’ll go deeper into backlighting below, or you

    can move onto the Local Dimming section.


    Three basic illumination forms have been used in LCD TVs:

    CCFL backlighting, full-array LED backlighting, and LED edge

    lighting. Each of these illumination technologies is different

    from one another in important ways. Let’s dig into each.

    CCFL Backlighting

    CCFL backlighting is an older, now-abandoned form of

    display technology in which a series of cold cathode lamps sit

    across the inside of the TV behind the LCD. The lights

    illuminate the crystals fairly evenly, which means all regions

    of the picture will have similar brightness levels. This

    affects some aspects of picture quality, which we discuss in

    more detail below. Since CCFLs are larger than LED arrays,

    CCFL-based LCD TVs are thicker than LED-backlit LCD TVs.

    Full-array backlighting

    Full-array backlighting swaps the outdated CCFLs for an

    array of LEDs spanning the back of the screen, comprising zones

    of LEDs that can be lit or dimmed in a process called local

    dimming. TVs using full-array LED backlighting to make up a

    healthy chunk of the high-end LED TV market, and with good

    reason — with more precise and even illumination, they can

    create better picture quality than CCFL LCD TVs were ever able

    to achieve, with better energy efficiency to boot.

    Edge lighting

    Another form of LCD screen illumination is LED edge

    lighting. As the name implies, edge-lit TVs have LEDs along the

    edges of a screen. There are a few different configurations,

    including LEDs along just the bottom, LEDs on the top and

    bottom, LEDs left and right, and LEDs along all four edges.

    These different configurations result in picture quality

    differences, but the overall brightness capabilities still

    exceed what CCFL LCD TVs could achieve. While there are some

    drawbacks to edge lighting compared to full-array or direct

    backlight displays, the upshot is edge lighting that allows

    manufacturers to make thinner TVs that cost less to


    To better close the local-dimming quality gap between

    edge-lit TVs and full-array back-lit TVs, manufacturers like

    Sony and Samsung developed their own advanced edge lighting

    forms. Sony’s technology is known as “Slim Backlight Master

    Drive,” while Samsung has “Infinite Array” employed in its

    line of QLED TVs. These keep the slim form factor achievable

    through edge-lit design and local dimming quality more on par

    with full-array backlighting.

    What is local dimming?

    Local dimming is a feature of LED


    tv/]LCD TV[/url]s wherein the LED light source behind the LCD

    is dimmed and illuminated to match what the picture demands.

    LCDs can’t completely prevent light from passing through, even

    during dark scenes, so dimming the light source itself aids in

    creating deeper blacks and more impressive contrast in the

    picture. This is accomplished by selectively dimming the LEDs

    when that particular part of the picture — or region — is

    intended to be dark.
