Problems solved by technology

Driving in this way can reduce motion blur, but it requires twice the scanning speed compared to the normal case, so the manufacturing cost of the device that realizes this function increases, and the power consumption increases

Embodiment Construction

[0083]

[0084] FIG. 1 is a block diagram showing the overall configuration of an active matrix display device according to an embodiment of the present invention. The display device includes a display unit (display panel) 100 , a scanning signal line driving circuit 200 , a data signal line driving circuit 300 , a display control circuit 400 , a current supply unit 500 , and a coupling line driving circuit 600 .

[0085] The display unit 100 is a display panel configured by arranging a plurality of pixel formations including light-emitting elements made of organic EL and thin film transistors described later on a glass substrate, and the plurality of pixel formations are formed in an m×n matrix. . In addition, since the structure of such a display part 100 is a well-known structure, detailed description is abbreviate|omitted.

[0086] The scanning signal line driving circuit 200 is connected to n scanning signal lines, and outputs scanning signals having a predetermined pe...

Abstract

It is possible to provide an active matrix type display device which has a simple configuration for driving black insertion in each pixel formation unit and which can easily restore a display state before a black display even after the black display. The display device includes a pixel formation unit having a coupling capacity (9) and a coupling line (8) arranged in parallel to a scan signal line (6) for drive with an appropriate voltage, so as to easily set a gate voltage of a drive element (2) via the coupling capacity (9) to a voltage of the black display. The coupling capacity (9) has a small size and can be formed easier than a TFT. Moreover, by changing the potential of the coupling line (8) in the reverse direction with the same change amount as the potential change of the coupling line (8) for setting the gate voltage of the drive element (2) to a voltage to obtain the black display, it is possible to easily restore the gate voltage so as to obtain the data signal potential corresponding to the display state before the black display even after performing the black display.

Description

technical field [0001] The present invention relates to an active-matrix display panel, a display device, and a driving method thereof, and more specifically, to an active-matrix display panel, a display device, and its driving method. Background technique [0002] In recent years, as the demand for light-weight, thin, and high-speed response displays has increased, research and development of organic EL (Electro Luminescence, electroluminescence) displays and FED (Field Emission Display, field emission display) display devices is actively going on. In addition, matrix display devices are broadly classified into passive matrix display devices and active matrix display devices. However, in recent years, there have been increasing demands for an increase in the number of display pixels and an increase in display speed due to high resolution. Source matrix type display devices are becoming mainstream. [0003] In particular, active matrix organic EL displays have been widely...
