Abstract

The invention provides a display panel driving device, an operation method thereof and a source electrode driver of the display panel driving device. The display panel driving device comprises a time schedule controller and the source electrode driver, wherein the time schedule controller outputs display data and error checking data; and the source electrode driver generates source electrode driving signals for driving the display panel according to the display data provided by the time schedule controller, and checks whether the display data are wrong or not according to the error checking data provided by the time schedule controller. The display panel driving device can prevent wrong source electrode driving signals from being written into the display panel.

Description

Technical field [0001] The present invention relates to a display device, and more particularly to a display panel driving device, an operating method of the display panel driving device, and a source driver thereof. Background technique [0002] In the conventional display panel driving device, the data / control signal transmission between the timing controller and the source driver is only unidirectional, that is, from the timing controller to the source driver. The timing controller frequently transmits a large amount of display data to the source driver. During the transmission of display data from the timing controller to the source driver, various types of noise, such as electromagnetic interference (EMI), may change the display data. When the source driver receives wrong display data, the source driver will use the wrong source driving signal to drive the display panel. However, the conventional source driver cannot determine whether the display data received from the tim...
