A film cutting device includes a stage which supports a circuit film, a cutter disposed on the stage to cut the circuit film, a vibration horn connected to the cutter, where the vibration horn vibrates the cutter in a first direction based on an ultrasonic wave, and a cooler which cools the cutter.

Film cutting device, film cutting method using the same, and display device including circuit film cut by the same

An apparatus for manufacturing a display device, includes: a stage; a temperature controlling portion on the stage, and to receive a member seated on the temperature controlling portion; and a jig portion facing the temperature controlling portion, the jig portion to move linearly, and to receive an adhesive member. The jig portion includes: a first support plate; a second support plate facing the first support plate; and a pressurization plate on the first support plate and the second support plate, the pressurization plate to receive the adhesive member thereon. An end of the pressurization plate is spaced further from the member than an end of the first support plate and an end of the second support plate when the member is seated on the temperature controlling portion.

Method for measuring force of adhesive member for manufacturing display device

A display apparatus includes a printed circuit board including first to fourth output pad regions and a flexible circuit board having a first end connected to a display panel and a second end connected to the printed circuit board. The first output pad region includes a 1-1output pad group and a 1-2output pad group, the second output pad region includes a 2-1output pad group and a 2-2output pad group, the fourth output pad region includes a 4-1output pad group and a 4-2output pad group, and the printed circuit board includes a first input terminal electrically connected to the 1-1output pad group, a second input terminal electrically connected to the 2-2output pad group, a third input terminal electrically connected to the first input terminal, and a fourth input terminal electrically connected to the 4-2output pad group.

Display apparatus including a display panel with multiple pads

Provided is a display apparatus. The display apparatus includes a flexible circuit board including flexible pads, a main circuit board including main pads, and a display panel including a plurality of pixels connected to the flexible circuit board and configured to receive a signal from the driving chip. In each of the flexible pads and the main pads, a portion of the pads is gradually tilted from pads disposed at a center to pads disposed at an outer side among the pads, and a tilted angle of a main pad disposed at the outermost side of the main circuit board is greater than that of a flexible pad disposed at the outermost side of the flexible circuit board.

Display apparatus
