Mobile terminal having an LED backlight unit
First Claim
1. A terminal comprising:
- a housing;
a display comprising;
a liquid crystal display provided to one side of the housing; and
a backlight including a plurality of light emitting diodes for outputting backlight provided to a backside of the liquid crystal display; and
a controller adapted to control the backlight to selectively adjust brightness of the light emitting diodes, wherein the controller is to control one or more objects to be displayed on the display and to selectively control the brightness of at least one of the light emitting diodes corresponding to the one or more objects, wherein the controller is to control at least one of the light emitting diodes located at a first distance from a reference point to emit light by a first brightness and to control one or more light emitting diodes located more than the first distance relative to the reference point to emit light by a second brightness.

Abstract
A mobile terminal having a display unit provided with an LED backlight and controlling method thereof are disclosed. The present invention includes a housing, a display unit including a liquid crystal display provided to one side of the housing and a backlight unit including a plurality of light emitting diodes for a backlight provided to a backside of the liquid crystal display and a control unit controlling the backlight unit to selectively adjust brightness of the light emitting diodes in part. Accordingly, a mobile terminal according to at least one of embodiments of the present invention controls light emission of an LED backlight locally, thereby providing more various display visual effects. And, a mobile terminal according to one embodiment of the present invention is able to use at least one portion of the light emitted from an LED BLU of a display unit as an illumination of a main body without using a separate light source for external illumination. Moreover, the illumination of the main body is able to play a role as a transmitter in a visible light communication.

9. A terminal comprising:
- a display screen;
a backlight including light emitting diodes to emit light towards the screen; and
a controller to selectively control brightness of light from the light emitting diodes, wherein the controller is to control a first light emitting diode to emit a first level of light and a second light emitting diode to simultaneously emit a second level of light, wherein the first level of light is to illuminate an object on the screen and the second level of light is to illuminate an area on the screen which does not include said object, wherein the first level of light is brighter than the second level of light, wherein the first level of light illuminates the object which includes a first icon having a first preference and the second level of light illuminates said area which includes a second icon having a second preference, and wherein the first preference is greater than the second preference. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
