摘要： A first path for directly inputting a control signal from the outside to a data signal processor and a second path for inputting a control signal generated by a bus interface to the data signal processor can be selectively switched by a switching portion. At the test time of a timing controller, the first path is selected by the switching portion so that the control signal is directly input to the data signal processor without being passed through the bus interface having a slow operation clock, and thus the timing controller can be reliably tested. At the normal use time, the second path is selected by the switching portion, thereby the control signal is input via the bus interface to various kinds of processors such as the data signal processor, and thus the normal operation can be reliably treated.

摘要： A liquid crystal display device includes liquid crystal pixels arrayed substantially in a matrix, a vertical driving circuit that selects the rows of pixels for video signal writing and for non-video signal writing, a horizontal driving circuit that writes a video signal in the pixels of a row selected for the video signal writing and a non-video signal in the pixels of a row selected for the non-video signal writing, and a control circuit that controls operation timings of the horizontal driving circuit and vertical driving circuit. In particular, the vertical driving circuit is configured to set a selection pattern for disabling an overlap between a selection period of selecting the pixels of each row for the video signal writing and a selection period of selecting the pixels of another row for the non-video signal writing, based on enable signals from the control circuit.

摘要： A display panel control circuit includes a controller which processes external image data and sync signals from an external signal source, and source and gate drivers which drive a display panel on the basis of processed results from the controller. The controller is configured to provide predetermined internal image data and sync signals which are generated immediately after supply of power and processed instead of the external image data and sync signals, and whose processing results are temporarily output to the source and gate drivers.
