Embodiment Construction

[0027] The following is a detailed description of preferred embodiments of the present invention, with reference to the accompanying drawings as an example.

[0028] Attached figure 2 A diagram showing a display device using COF according to the first embodiment of the present invention.

[0029] Reference attached figure 2 , The display device includes a display panel 30, a COF 80 having a connecting portion 20 on which the display panel 30 is placed and a chip portion 10 on which a driving chip 60 is placed, data lines and scan lines 40 and 50 respectively extending from the display panel 30, In addition, the reference number '70' refers to the SMD part.

[0030] The scanning line 50 is connected to the COF 80 in a straight line from the display panel 30 toward an IC (Integrated Circuit) chip (hereinafter referred to as a chip) 60 for driving the display device. The data line 40 that forms a curve from the display panel 30 toward the chip 60 is connected to the COF 80. And the...

Abstract

Disclosed is a display device using a COF operating with a low driving voltage. The present invention includes a display panel, a COF having a connection part on which the display channel is placed and a chip part on which a chip is placed, data lines connected to the COF in a direction toward the chip, the data lines forming curves starting from the display panel, scan lines straightly connected to the COF, the scan lines starting from the panel in the direction toward the chip, scan line connection lines on the connection part, the scan line connection lines connecting the scan lines electrically to the COF, and data line connection lines on the connection part, the data line connection lines connecting the data lines electrically to the COF.

Description

Invention field [0001] The invention relates to a display device using a chip on film (COF) operating with a low driving voltage. Background technique [0002] Recently, a display device with a wide image area has become the mainstream of the times. In order to improve image quality, the display device has more data lines and scan lines. [0003] However, if the number of scanning lines is increased in order to improve the image quality of a display device with a simple matrix structure, it will be greatly restricted in driving the display device. [0004] Attached figure 1 An illustration of a display device using COF according to the related art is shown. [0005] Reference attached figure 1 , The data line is directly connected from the display panel to the chip-on-film (hereinafter referred to as COF). And, the scan lines respectively arranged on the left and right sides of the display panel extend from the display panel to form a curve to connect...
