Embodiment Construction

[0031] In many display technologies, digital driving methods have advantages over analog driving methods because digital driving methods are generally not subject to significant deviations in the characteristics of the driving TFTs associated with using the on / off states of the driving thin film transistors (TFTs) influences. Therefore, the digital driving method is more widely used for large-sized flat panel displays than the analog driving method.

[0032] In addition, the digital driving method can also be used to substantially prevent mottle (eg, irregularity or unevenness in image quality) when displaying images. However, this method increases the number of times a data signal representing an image frame is applied compared to the analog driving method. Therefore, the digital driving method consumes more power than the analog driving method due to the charging and discharging operation of the data load generated by the resistance or parasitic capacitance of the data line...

Description

technical field [0001] The described technology generally relates to a display device and a driving method thereof, and more particularly, to a display device that reduces power consumption with a digital driving method. Background technique [0002] A display device includes a display panel formed of a plurality of pixels arranged in a substantially matrix form. A display panel generally includes a plurality of scan lines formed in a row direction and a plurality of data lines formed in a column direction. Each pixel may be driven by scan and data signals received from corresponding scan and data lines, respectively. [0003] According to the driving mechanism of the display device, the display device can be classified into a passive matrix type light emitting display device and an active matrix type light emitting display device. Based on the resolution, contrast, and response time of the display device, the general trend is towards an active matrix type that selectively...
