Embodiment Construction

[0025] In the following detailed description, only specific exemplary embodiments of the present invention have been shown and described, simply by way of example. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. Accordingly, the drawings and description are to be regarded as illustrative in nature and not restrictive. Throughout this specification, the same reference numbers refer to the same elements.

[0026] Throughout this specification and the claims, when an element is described as being "coupled" to another element, the element can be "directly coupled" to the other element, or the element can be "electrically coupled" through one or more additional elements to another element. Additionally, unless expressly stated to the contrary, the term "comprising" should be understood to mean the inclusion of stated elements and not the exclusi...

Abstract

A display device and a method of driving the display device are provided. The display device includes a scan driver for transmitting scan signals to a plurality of scan lines, a data driver for transmitting data signals to a plurality of data lines, and a signal controller for controlling the transmissions of the scan driver and the data driver. The scan driver and the data driver are configured to begin operating in response to a reset signal. The signal controller is configured to detect the reset signal, to determine whether the detected reset signal is a normal reset signal or an abnormalreset signal applied after an on time at which power is supplied to the scan driver and the data driver, and to apply a normal reset signal when the detected reset signal is determined to be an abnormal reset signal.

Description

technical field [0001] The present invention relates to a display device and a method of driving the display device. Background technique [0002] When the display apparatus starts up and starts to operate, a reset signal is input to a driver that controls the operation of the display apparatus. The reset signal is a start signal to initialize the driver to operate the display device. [0003] After power is supplied to the display device, the reset signal has a predetermined waveform. When the reset signal is sensed, the driver starts to operate. In some examples, the reset signal may not have the predetermined waveform, or the driver may not recognize the reset signal. Then, the drive does not start normally, and therefore, the display apparatus may not function normally. In particular, when the display apparatus operates abnormally, during the initial operation of the driver, abnormal driving voltages and / or abnormal driving commands are provided to control the driver...
