Abstract:
A display device for converting a resolution of a video signal that has been inputted, the display device being capable of displaying the video signal thus converted on a display panel, comprising:the display panel; a memory that is capable of storing said video signal; a processing circuit that converts the resolution of the video signal to the resolution of the display panel, when the resolution of the video signal and the resolution of the display panel are different from each other; and a memory control circuit for synchronizing said horizontal synchronous signal and said vertical synchronous signal of the video signal that is outputted from said memory, respectively, with said horizontal synchronous signal and said vertical synchronous signal of said video signal that is inputted into said memory, wherein frequencies of said horizontal synchronous signal of said video signal that is outputted from said memory are higher than said horizontal synchronous signal of said video signal that is inputted into said memory, when the resolution of said display panel is larger than the resolution of the video signal.
