Current Consumption Analysis of LCD and AMOLED Display Technologies: An Approach Based on Multi-Text Input Modalities

When evaluating battery consumption in mobile devices in the fifth-generation (5G) network, it is crucial to consider the display technology used, as different technologies consume varying amounts of energy. Liquid Crystal Display (LCD) and Dynamic Active Matrix Organic Light-Emitting Diode (AMOLED) are two prevalent display technologies. LCD is an older technology that remains widely used due to its affordability and widespread availability. On the other hand, Dynamic AMOLED is a more advanced display technology in modern smartphones. Typing on a keyboard, swiping through screens, and using voice commands consume different amounts of power. This paper aims to analyze the current consumption of display technologies, in different baseline scenarios, and text input methods. A comparative analysis was conducted between smartphones equipped with LCD and Dynamic AMOLED displays. The results demonstrated that Dynamic AMOLED technology consistently saved energy, achieving reductions of up to approximately 40% in specific modes such as standby or reading. In contrast, PLS LCD has around 30% higher average current consumption than Dynamic AMOLED. Dynamic AMOLED offers notable advantages in energy savings under specific modes, understanding the nuances between display technologies and input modalities helps users and manufacturers of 5G mobile devices make informed decisions about smartphone selection and usage patterns.
