1. Field
Methods and apparatuses consistent with exemplary embodiments relate to an image display apparatus and an image display method, and more particularly, to an image display apparatus and an image display method capable of substantially saving power consumption.
2. Description of the Related Art
Cathode ray tubes (CRTs) have been widely used in display apparatuses such as televisions (TVs) and computer monitors. However, CRTs use a method of emitting cathode electrons from an electron gun to glass wool covered with a fluorescent material to generate light, and thus have large sizes, which is disadvantageous. Thus, a flat panel display (FPD) technology emerged, which drastically reduces the thickness of a display apparatus.
Examples of flat panel displays include a liquid crystal display (LCD) that uses a liquid crystal, a plasma display panel (PDP) that emits light by using a principle of gas discharge such as that employed in neon signs, an organic light emitting diode (OLED) panel that emits light by applying a current to a fluorescent organic compound, a field emission display (FED), an electro luminescence display (ELD), and so forth.
Various technologies are proposed to reduce power consumption in flat panel displays. However, as the size of display panels increases and the resolution becomes higher, the power saving technologies proposed in the related art have limits to substantially reducing power consumption. Therefore, there is a need for a method that may substantially reduce power consumption in a display apparatus.
