Display device with signal lines routed to decrease size of non-display area

摘要

A display device includes a display panel, a panel driver, panel-side output terminals, image signal lines, and control signal lines. The terminals are disposed in a non-display area of the display device and connected to the panel driver. The image signal lines are routed in the non-display area from the terminals to cross a long edge of the panel driver and spread in a fan-like form toward the display area. The control signal lines including first lines and second lines are routed in the non-display area from the terminals toward a display area of the display device. The first lines are routed from the terminals to cross the long edge and along the image signal lines toward the display area. The second lines each including portions having a width larger than the first lines are routed from the terminals to cross a short edge of the panel driver.

主权项

1. A display device comprising:
a display panel including a display area configured to display images and a non-display area outside the display area; a panel driver mounted in the non-display area and configured to drive the display panel by processing input signals supplied by an external signal source and inputting output signals generated from the input signals to the display panel, the panel driver having an elongated shape with a longitudinal direction thereof along an edge of the display panel; panel-side output terminals disposed in the non-display area and connected to the panel driver; image signal lines disposed in the non-display area and routed from the panel-side image output terminals so as to cross a long edge of the panel driver and spread in a fan-like form toward the display area, the image signal lines being configured to transmit image signals included in the output signals; and control signal lines disposed in the non-display area and routed from the panel-side output terminals toward the display area, the control signal lines being configured to transmit control signals included in the output signals and including:
first control signal lines routed from the panel-side output terminals so as to cross the long edge of the panel driver and along the image signal lines toward the display area; andsecond control signal lines routed from the panel-side output terminals so as to cross a short edge of the panel driver, each of the second control signal lines having at least a portion, a width of which is larger than a width of the first control signal lines.
