Active matrix driving display device and image displaying method using the same

摘要

LCD device includes two substrates, a first and second color filters, two liquid crystal layers. The first color filters are formed on portions of the second substrate corresponding to border area The second color filters are formed on portions of the second substrate corresponding to the display area except the border area. A first liquid crystal layer between the first and the second substrate is comprised in border area, and a zero electric field is formed on the first liquid crystal layer so as to completely transmit light incident into the first liquid crystal layer therethrough. A borderline having various colors can be displayed by forming various patterns of color filters having various colors on portions of the second substrate corresponding to the border area under normally white mode, thereby producing picture frame effect while images are displayed on the screen.

主权项

1. An active matrix driving display device comprising:
a timing controller generating a first dummy line data, a second dummy line data, a first dummy pixel data and a second dummy pixel data, receiving a first display area data to generate a second display area data that is obtained by adding the first and second dummy pixel data to the first display area data, and generating a first control signal that allows the second display area data and the second dummy line data to be outputted to each row of a display area having a plurality of rows and columns, the first dummy line data having a first color information for each pixel in a first border area corresponding to an upper borderline, the second dummy line data having a second color information for each pixel in a second border area corresponding to a lower borderline opposite to the upper borderline, the first dummy pixel data having a third color information for each pixel in a third border area corresponding to a left borderline, the second dummy pixel data having a fourth color information for each pixel in a fourth border area corresponding to a right borderline, the first display area data having a fifth color information for each pixel in the display area except the upper, lower, left and right borderline; a first driver generating a first dummy line driving signal and a second dummy line driving signal base on the first control signal and generating a plurality of second control signals base on the first control signal, the first dummy line driving signal allowing the first dummy line data to be displayed on the first border area, the second dummy line driving signal allowing the second display area data to be displayed in a row unit on the display area except the upper, lower, left and right borderline; a second driver receiving the first dummy line data, the second display area data and the second dummy line data from the timing controller and allowing the first dummy line data, the second display area data and the second dummy line data to be displayed on the display area in response to the first dummy line driving signal, the second control signals and the second dummy line driving signal.
