Abstract

The invention provides a display apparatuses having an active transflective device. The display apparatus includes an active transflective device and a device panel. The active transflective device is configured to electrically control light transmissivity and light reflectivity. The display panel is configured to form an image by modulating at least one of light reflected and light transmitted by the active transflective device.

Description

technical field [0001] The present invention relates to a display device that properly adjusts reflection and transmission of incident light to improve brightness and reduce power consumption. Background technique [0002] Due to the recent increase in the use of portable devices such as mobile phones, personal digital assistants (PDAs), portable multimedia players (PMPs), and digital multimedia broadcasting (DMBs), display devices with low power consumption and good outdoor visibility are required . [0003] Therefore, research on a transflective liquid crystal display (LCD) having dual functions of a reflective display device and a transmissive display device has been conducted. The transflective LCD forms an image using a backlight unit and / or outdoor light, so that visibility of the display can be secured and power consumption can be easily reduced even when the transflective LCD is used in a bright environment including sunlight. In this case, the area of ​​the liquid...
