The backlight is another component that is essential to the operation of the LCD module. It plays a significant part in the display. TFT LCD panels, in contrast to OLED displays, are incapable of actively producing light; as a result of this limitation, they are classified as passive devices rather than active ones. Due to the see-through nature of the TFT LCD panel, the backlight is the sole factor in determining whether or not the panel is capable of producing the required degree of brightness. In a TFT LCD display module, it is possible for a good backlight source to deliver light that is uniform, which will result in a display effect that is more nuanced and uniform. This is possible because it is possible for the backlight source to deliver light that is uniform. By delivering light that is uniform, it is possible to achieve the desired effect. As a company that possesses this competence, Huizhou Kelai Electronics is able to personalise backlight modules so that they conform to a wide range of specific needs. In addition to the mechanical structures that we are familiar with, such as size and shape, we have extensive expertise in a variety of other areas, including brightness levels, the NTSC colour gamut, colours, driving circuits, heat dissipation, longevity, power consumption management, connections, and other components. This knowledge has the potential to be applied to a wide number of facets associated with the product.
100–2000 nits; it is evident that due to differences in size and design, different LCD panel devices would have differing brightness constraints. There is a possible range of 100–2000 nits for these limitations. These limitations can have an intensity of anywhere from one hundred to two thousand nits. We are able to attain 1000nits on the great majority of screens, which satisfies the standards for readability when exposed to sunlight. These standards were developed to ensure that digital content can be easily read.
It is difficult to significantly enhance the value of NTSC for the traditional backlight industry because of the competition from other standards. Our organisation is now conducting research and development on the quantum dot technology, which has the potential to easily circumvent 100% of NTSC's security measures. This leads to an increase in the brightness of the image as well as a more natural appearance for the colours in the image that are too saturated.
3.Color temperature: the white backlight that's utilised for TFT LCD displays is the one that's used the most out of all the available colours for the backlight. When discussing white, there is a normal white that has a temperature of approximately 5500K, a warm white that has a temperature of about 3500K (and seems yellow), and a cold white that has a temperature of about 6500K (and appears very cold). We are able to change the colour of the LED lighting to correspond with the preferences you've expressed or the settings that you've chosen for the user interface.
each the voltage and current needs of a small-sized backlight are relatively low, and the vast majority of motherboards are able to provide it with sufficient values in each of those categories. Some products with high brightness requirements, particularly those with larger screens, may have dozens of LEDs, each of which may require either a high voltage or a high current. Because of this, backlight driver circuits are required in order to meet the requirements of these LEDs. In addition to this, we will be providing driver circuits for these products so that we can meet the output requirements of our clients and reduce the amount of time needed for secondary development.
The backlight also has to be connected using a cable. Through an FPC, this cable may be linked to the LCD's front panel connector (FPC), and a port may be used to control it. An additional cable that is connected by a connector can be used as an alternative method of controlling the illumination. The structure of your product will determine how this works out. Cables continue to be our control method of choice whenever it is practical to do so since they offer a higher level of protection even when the current flowing through them is fairly high.
When it comes to LCD screen products that have a high brightness, their power consumption is frequently too high, and their creation of heat also increases, which is why they require a good structure for heat dissipation. This is because the higher the brightness, the more light is reflected back into the screen, which in turn creates more heat. When creating a backlight, it is essential to give careful consideration to the construction of an acceptable heat dissipation structure in advance, as well as the addition of heat dissipation films and the use of aluminium substrates. All of these things need to be taken into account at the very beginning of the design process.
When compared to the power consumption of TFT LCD liquid crystal modules, the power consumption that is required by the backlight source is substantially larger. It is reasonable to assume that the backlight is responsible for the most share of the total amount of power that is consumed by LCM. When given the option to choose between the level of brightness and the amount of electricity it uses, some consumers go with the latter. This is because the product in issue can be a handheld gadget that gets its power from a battery. Such a device is not allowed to have an excessive amount of power consumption because this will shorten the amount of time the battery will last while powering the product. By incorporating film materials into the display, such as DBEF and brightening films, we are frequently able to increase the display's brightness without concurrently causing an increase in the amount of power that it uses.
The material that has been presented up until this point is an introduction to the process of customising the backlight of LCD modules, which involves a variety of aspects that are quite important. A customization design strategy that is more comprehensive is required because there is a need for it. We would like to use this opportunity to offer Huizhou Kelai Electronics a very warm welcome.
