    Abstract: A circuit board assembly includes a main board and a connection board attached to the main board. The connection board includes a base board including a connecting pad area and a mounting area, wherein the connection board is attached to the main board in the connecting pad area, and wherein the mounting area is spaced apart from the connecting pad area in a first direction and includes a driving chip mounted thereon. The connection board further includes first connection pads disposed on the connecting pad area of the base board, and second connection pads disposed on the connecting pad area of the base board. The main board includes first main pads connected to the first connection pads in a one-to-one connection and a second main pad connected to the second connection pads in a many-to-one connection.

    Abstract: A flexible circuit film including a first flexible film, a second flexible film facing the first flexible film, and a plurality of wirings arranged between the first flexible film and the second flexible film. The wirings have different widths and bend in different directions, and a guide film including a material more rigid than the first and second flexible films is arranged on ends of the first flexible film. The guide film includes a tear-preventing portion overlapping with a bending portion of a shortest one of the wirings while covering portions of an inner edge near inner corners of a U-shaped flexible circuit film.

    Abstract: A display device includes gate lines, data lines, pixels, a gate driver, a data driver, and a timing controller. The gate lines extend in a first direction. The data lines extend in a second direction crossing the first direction. Each of the pixels is connected to a corresponding gate line of the gate lines and a corresponding data line of the data lines. The gate driver is configured to drive the gate lines. The data driver is configured to drive each data line of the data lines in response to a corresponding data signal. The timing controller is configured to, in response to an image signal and a control signal, apply the corresponding data signals to the data driver and control the gate driver. Each corresponding data signal reflects a kickback compensation value corresponding to a distance between the gate driver and the corresponding data line in the first direction.

    Abstract: A display device is disclosed that includes a display panel, a data driver, a timing controller, a memory device, and a power voltage generator. The display panel includes pixels. The data driver is configured to apply data voltages to the pixels. The timing controller is configured to control the data driver, to generate a test strobe signal by shifting a phase of a strobe signal, to perform a test write operation and a test read operation with the memory device based on the test strobe signal, and to increase a power voltage when an error bit occurs in the test write operation and the test read operation. The memory device is configured to sample memory data received from the timing controller using the strobe signal and to store sampled memory data. The power voltage generator is configured to apply the power voltage to the memory device.
