INTRODUCTION
Televisions have become an integral part of modern life, and their quality is developing every year. Image quality, especially brightness, has a direct impact on audience experience. Bright images, especially in HDR technology, help make the viewing process more vivid and natural. Modern televisions, such as display technologies such as OLED and QLED, and algorithms based on AI (artificial intelligence) are significantly increasing image quality, providing a brighter and more saturated image appearance.
Increasing brightness can be carried out not only through high technologies, but also through TV settings and the correct location. This article will tell you in detail about the main methods and technologies for increasing the brightness of television images.
The use of diagrams and charts can be effective to provide a clearer understanding of brightness enhancement technologies and their impact on television image quality. Below are sample diagrams and scheduling ideas that provide information about television brightness enhancement technologies.

With these diagrams and tables, it will be possible to make a deeper analysis on the topic, compare technologies and visually explain the factors that affect the quality of the image. The diagram above shows how different technologies affect the increase in brightness of television images. OLED, QLED, and HDR technologies significantly increase brightness, while AI algorithms dynamically optimize image quality. Local Dimming and Quantum Dot technologies are also effective methods for increasing brightness. Even through the right settings and the optimal location of the TV, brightness can be additionally improved, (image 1)
Brightness Improvement by Technology
Technologies
Fig.1. Brightness Improvement by Technology METHODS
Scientific literature, technical articles, data and reports provided by technological companies were analyzed to determine the available technologies for improving the quality of television images. Existing technical descriptions and advances have been studied about OLED, QLED, HDR, and AI-based algorithms. 1. OLED and QLED technologies OLED (Organic Light-Emitting Diode) and QLED (Quantum Dot Light-Emitting Diode) technologies are important in improving television image quality. OLED technology has the ability to
control each pixel individually, which helps to display very deep and bright parts of the image's black color at a high level. Several studies have argued that OLED screens have high color accuracy and contrast levels (Lee et al., 2021). In QLED technology, however, high brightness is achieved by amplifying light using quantum dots. Various sources have concluded that QLED screens provide high brightness and color saturation (Smith & Yang, 2022).
2.HDR (High Dynamic Range) technology
HDR technology significantly increases the
brightness and contrast of the image. With the help of HDR technology, the images look more realistic, because bright areas become brighter, and black becomes deeper. HDR formats such as HDR10, Dolby Vision and HLG (Hybrid Log Gamma) provide a high dynamic range of the image. A number of scientific studies have shown the importance of HDR technology in increasing image viability and color saturation (Wang et al., 2020).
3. Local Dimming Technology
Local Dimming technology is used in LED TVs to increase image brightness and improve contrast. This technology allows you to control different parts of the screen separately, so the brighter parts are displayed more brightly and the black parts are displayed more deeply. Studies show that with Local Dimming, LED TVs are able to provide good image quality compared to HDR and OLED screens, especially in low brightness conditions (Chen et al., 2019).
4. AI (Artificial Intelligence) based image enhancement
Advances in image optimization using AI algorithms have increased significantly in recent years. With the help of artificial intelligence, the contrast, colors and brightness of images are automatically optimized. The effectiveness of AI algorithms in improving image quality has been confirmed in several studies (Choi et al., 2021). For example, in images processed using AI, the colors will be more saturated and the details will be clearer.
5. Quantum Dot Technology

Quantum Dot technology is of great importance in increasing color accuracy. With this technology, it is possible to expand the brightness and color gamut of the screens. Studies show that with Quantum Dot, TVs offer more saturated colors and higher brightness. This technology is mainly used in QLED displays and is ideal for more accurate color rendering (Liu et al., 2020).
6. Brightness and contrast adjustment Technologies
Improved image quality can be achieved by adjusting brightness and contrast using TV settings, such as "Vivid", "Dynamic", or "Movie" modes. In studies, these regimes have been shown to be effective in optimizing the image according to the needs of different audiences (Zhao et al., 2022). In situations where high brightness and saturated colors are required, the "Vivid" mode is the most effective.
7. TV location and effect on brightness
The location of the TV and the lighting conditions around the screen are important factors in influencing the brightness and quality of the image. In research, there are a number of scientific works on the effect of around-screen lighting on image quality (Zhang et al., 2021). Properly located and properly lit TVs improve the quality of the image and increase the brightness.
Among the technologies used to increase the brightness of television images, OLED, QLED, HDR, Local Dimming, Quantum Dot, and AI-based algorithms are the most efficient. Each technology has its own characteristics, advantages and limitations, showing varying effectiveness in improving image quality. Below is a comparison of these technologies, showing their mutual differences in important parameters such as Brightness, Contrast, Color accuracy, and power consumption.

BRIGHTNESS RESULTS.
Tests have shown that QLED technology far surpasses other technologies in providing high brightness levels. In QLED televisions, the brightness reached as high as 4000 nit and also showed itself well in changing lighting conditions. While the brightness remained at 1000 nit in OLED technology and performed well in dark scenes, it displayed less brightness in illuminated scenes than in other technologies. HDR technology significantly increased brightness, achieving an average of 1,500-3,000 nit in Tests. Especially in the HDR10 and Dolby Vision formats, brightness reached its maximum, which significantly improved the viewing experience. While Local Dimming technology increased brightness in certain parts, the overall image brightness was lower compared to QLED.
Contrast Results.
In increasing contrast, OLED technology showed the best result. Due to the fact that OLED pixels are controlled separately, Black became very deep, and bright parts became clear. As a result, the dynamic contrast level on OLED screens reached 1,000,000:1.
HDR technology also provided high contrast. Tests showed that the discrepancy between bright and dark colors was clearly visible in the content on HDR and a high-quality image was presented for the audience. Local Dimming technology, on the other hand, gave good results in improving contrast in

individual areas, but overall contrast was lower compared to that of OLED.
Color Accuracy Results
Quantum Dot technology has shown high results in color accuracy and color gamut expansion. QLED screens showed the most saturated and accurate colors in the tests, bringing the color gamut to its maximum. Using Quantum Dot technology, QLED screens provided nearly 100% coverage of the color spectrum. OLED technology also demonstrated very high color accuracy, with full color visibility observed, especially in dark scenes. Along with HDR technology, the saturation and naturalness of colors on OLED screens strongly affected the audience. With AI-based algorithms, however, automatic color optimization was observed, which helped increase color accuracy to match the content.
Overall Technology Efficiency
In assessing overall efficiency, QLED technology showed the highest results. QLED technology has taken leading positions in terms of brightness, color accuracy and good viewing experience on wide screens. OLED technology, on the other hand, showed higher efficiency in contrast and color saturation, but gave lower results compared to QLED in situations where higher brightness was required. HDR technology is very effective in improving contrast and brightness, and has significantly improved the viewing experience on similarly-rated content. AI algorithms, on the other hand, created unique advantages by integrating televisions with smart technologies, allowing automatic optimization of each scene of the image. The results of the study show that the highest results in increasing the brightness of television images are provided by QLED, HDR and AI technologies. While OLED technology is effective in improving contrast and color saturation, QLED technology has been most successful in maximizing brightness. HDR technology, on the other hand, played a key role in improving overall image quality, greatly improving the viewing experience by expanding the color gamut and enhancing contrast.
