Embodiment Construction

[0021] Exemplary embodiments will be described in detail below with reference to the accompanying drawings. This disclosure may, however, be embodied in various forms and should not be construed as limited to only the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be complete and thorough, and will fully convey the present invention to those skilled in the art. public scope. Throughout the present disclosure, like reference numerals refer to like parts in the drawings and examples.

[0022] When an element is defined by "connected to" or "coupled to" another element, it means that the former is directly connected or coupled to the latter, or another element is interposed between the two elements. On the other hand, when an element is defined as being "directly connected to" or "directly coupled to" another element, it means that no other element is interposed therebetween. Throughout this disclosure, the same reference numer...

Abstract

Provided are a source driver and a display device. The source driver may include: a gamma voltage generation unit configured to select and provide one or more of the gamma voltages in response to a first power down signal; an output buffer unit configured to provide a data voltage to a output terminal in response to a second power down signal; and a selection unit configured to provide the gamma voltage to the output terminal.

Description

technical field [0001] The invention relates to a source driver and a display device including the same. Background technique [0002] With the rapid development of semiconductor technology, the size and weight of display devices have been reduced. A flat panel display device such as a liquid crystal display (LCD) or an organic light emitting diode (OLED) display can be easily reduced in size and weight, and has relatively low power consumption. Thus, a driving device such as a source driver or a gate driver used in a display device also requires low power consumption. [0003] prior art documents [0004] patent documents [0005] Patent Document 1: KR10-2012-0059351 (published on June 18, 2012) Contents of the invention [0006] The object of the present invention is to provide a source driver with low power consumption. [0007] Another object of the present invention is to provide a display device with low power consumption. [0008] In one embodiment, the source...
