LCD TFT (Liquid Crystal Display with Thin-Film Transistor) displays use liquid crystals and a backlight to generate images. This technology is widespread due to its affordability and wide availability in various sizes and specifications. Although they provide good all-round performance, they typically have more limited viewing angles and lower contrast than OLED displays because the backlight can never be completely blocked.
OLED (Organic Light-Emitting Diode) displays have pixels that emit light themselves, eliminating the need for a backlight. This results in infinite contrast with perfect blacks, vibrant colors and very wide viewing angles. The technology also enables thinner, brighter and more energy-efficient displays, especially for darker images. Disadvantages are the higher cost and the risk of burn-in with prolonged static images.
The term 'LED display' generally refers to an LCD TFT display that uses an LED backlight instead of the outdated CCFL technology. These LEDs provide higher brightness, lower power consumption and longer life. This technology also allows for thinner designs. Although it is an improvement on traditional LCD, it retains the fundamental properties and limitations of LCD technology.
The ideal display choice is a trade-off between several factors. For projects where image quality, such as contrast and viewing angles, is critical, OLED is the superior option. If budget and overall usability are the priority, LCD TFT with LED backlight offers the best balance between price and performance. Aspects such as response time, lifetime and energy consumption must also be factored into the final decision.
