This has become a common display type for mid-range to high-end phones. OLED/AMOLED. OLED & AMOLED utilizes 'organic' LEDs which emits light and in the majority of cases does away with the need for the back-light of an LCD display resulting in a potentially thinner panel.
1 The model number is located on a small label located on the frame around the computer screen. (e.g., VGN-FW550F)  The computer information and compliance label, located on the bottom of the laptop case, indicates the actual model number.
The model represents the system itself, whereas the simulation represents the operation of the system over time. Simulation is used in many contexts, such as simulation of technology for performance optimization, safety engineering, testing, training, education, and video games. computer simulation (or sim) is an attempt to model a real-life or hypothetical situation on a computer so that it can be studied to see how the system works. By changing variables in the simulation, predictions may be made about the behaviour of the system.
