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 +70℃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 angleDoes high brightness of LCD panel lead to high power consumption?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 reflectivityLED light with large chip can increase brightness under the same power consumptionThe 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 IndustriesLiquid-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 دیدن لینک ها برای شما امکان پذیر نیست. لطفا ثبت نام کنید یا وارد حساب خود شوید تا بتوانید لینک ها را ببینید.
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.

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 Displays
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 دیدن لینک ها برای شما امکان پذیر نیست. لطفا ثبت نام کنید یا وارد حساب خود شوید تا بتوانید لینک ها را ببینید.
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?[size=medium]1. Too high temperature will cause devastating damage to the LCD strip screen[size=medium]（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.[size=medium]（2）If the operating temperature of the دیدن لینک ها برای شما امکان پذیر نیست. لطفا ثبت نام کنید یا وارد حساب خود شوید تا بتوانید لینک ها را ببینید.
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.[size=medium]2. The reason why temperature affects the luminous rate of the LCD bar screen:[size=medium]（1）As the temperature increases, the concentration of electrons and holes increases, the band gap decreases, and the electron mobility decreases.[size=medium]（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 display.[size=medium]（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 display.[size=medium]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 دیدن لینک ها برای شما امکان پذیر نیست. لطفا ثبت نام کنید یا وارد حساب خود شوید تا بتوانید لینک ها را ببینید.
to provide lighting, whereas LED LCD TVs used an array of smaller, more efficient light-emitting diodes (LEDs) to illuminate the screen.[size=medium]Since the technology is better, all LCD TVs now use LED lights and are colloquially considered LED TVs.

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.
