DISPLAY PANEL WITH ASPECT RATIO OF MATRIX-ARRAYED PIXEL, AND DISPLAY DEVICE THEREOF

摘要

PURPOSE: A display panel having the aspect ratio of matrix-arrayed pixels set to the predetermined value and a display device by using the display panel are provided to display the picture on the screen by adjusting the aspect ratio of pixel properly without lowering the quality of image. CONSTITUTION: A liquid crystal display device using an LCD panel(1) displaying computer output, wherein video signals of a predetermined television system are converted by a decoder into field-unit picture data, and frame-unit picture data obtained by a converter are supplied to an LCD panel to display a picture composed of such video signals. The picture is displayed on an effective screen of the display panel at the original aspect ratio of the video signals of a television system by changing the width-to-height ratio of each unit pixel formed on the effective screen of the display panel, on the basis of the ratio of the number of horizontal pixels to the number of vertical pixels of the frame-unit picture data, and also on the basis of the aspect ratio of the predetermined television system.
