Embodiment Construction

[0023] In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of various exemplary embodiments. It is evident, however, that the various exemplary embodiments may be practiced without these specific details, or with one or more equivalent arrangements. In other instances, well-known structures and devices are shown in block diagram form in order to avoid unnecessarily obscuring the various exemplary embodiments.

[0024] In the drawings, the size and relative sizes of layers, films, panels, regions, etc., may be exaggerated for clarity and descriptive purposes. Also, the same reference numerals denote the same elements.

[0025] When an element or layer is referred to as being "on," "connected to," or "coupled to" another element or layer, it can be directly on, connected to, or directly on the other element or layer. is coupled to another element or layer, or intervening elements or lay...

Abstract

The invention discloses a display panel and a display device including the display panel. The display panel includes: a display area including pixels; a non-display area including dummy pixels; and a switch circuit that transmits a data signal to the dummy pixels in response to a control signal. The display panel can use only one dummy pixel column to compensate defective pixels located in different data lines, and can minimize an area including a dummy pixel column (for example, a no-signal area) by including a divider and a switch circuit, the allocator The signal of the output line is buffered, and the switch circuit selects a portion of the signal of the output line and provides it to the dummy data line.

Description

technical field [0001] Exemplary embodiments relate to a display device. More particularly, exemplary embodiments of the inventive concepts relate to a display panel for repairing defective pixels and a display device. Background technique [0002] A display panel includes pixels, and when a transistor included in a pixel is defective or disconnected, the pixel cannot function. Recently, the display panel has further included dummy pixels and can display an image by using the dummy pixels instead of pixels having defects (eg, defective pixels). [0003] The display device may use the demultiplexer to provide the data signal to the display panel for cost reduction (or manufacturing cost of the display device). For example, the display device can sequentially provide three kinds of data signals (for example, red, green and blue data signals or R / G / B data signals) from the driving integrated circuit to the 1:3 multiplex output selection through one output line (or a demultip...
