Increasing the display brightness of screen modules can be achieved through various methods, but the specific effectiveness depends on the type, design, and limitations of the screen module. Below are some common methods to increase the display brightness of screen modules:

Adjusting Backlight Brightness:

Most liquid crystal displays (LCDs) use a backlight module to illuminate the screen. By increasing the backlight brightness, the display brightness of the screen module can be directly enhanced. This is typically done by adjusting the brightness of the LEDs or other light sources within the backlight module.

The range of brightness enhancement depends on the design and limitations of the backlight module. Some high-quality backlight modules may have a wide range of brightness adjustments, while some low-cost or limited modules may have a smaller adjustment range.

Using Brightness Enhancement Films (BEFs):

As mentioned, brightness enhancement films (such as prism sheets or BEFs) can focus light and increase the brightness of the screen module. These films are usually placed between the backlight module and the LCD panel, improving brightness by changing the direction of light propagation.

Different types of brightness enhancement films have different effects. Common enhancement films, such as ordinary prism sheets and multifunctional prisms, can increase brightness by about 40-60%. However, the specific effect depends on the design and configuration of the screen module.

Optimizing the Drive Circuit:

The brightness of an LCD is also influenced by the drive circuit. By optimizing the design and parameters of the drive circuit, the response speed and contrast of the LCD panel can be improved, thereby indirectly increasing brightness.

This requires professional electronic engineering knowledge and skills, and may necessitate modifications to the hardware of the screen module. Therefore, this method is typically used for customized screen modules or high-end professional applications.

Choosing High-Brightness LCD Panels:

When designing screen modules, selecting LCD panels with higher brightness can be an option. These panels generally have more efficient backlight modules and more advanced LCD technology, providing higher brightness and better display effects.

However, high-brightness LCD panels are usually more expensive and may require additional cooling measures to ensure stable operation.

It is important to note that there are limitations to how much the brightness of a screen module can be increased. The specific amount of brightness increase depends on the design of the screen module, the capability of the backlight module, the effectiveness of the brightness enhancement films, and the optimization of the drive circuit. Therefore, when increasing the brightness of a screen module, these factors should be comprehensively considered, and testing and verification should be conducted where possible to ensure the desired brightness enhancement effect is achieved.

Lastly, it is important to note that excessive brightness may cause discomfort or fatigue to the eyes. Therefore, when increasing the brightness of a screen module, user comfort and health factors should also be considered.
