Abstract: A driver includes a dummy stage and one or more additional stages coupled to the dummy stage. The dummy stage includes a first transistor coupled between an input terminal and an output terminal. The first transistor includes two electrodes forming at least a first capacitor to store at least a portion of static electricity received through the input terminal. The one or more additional stages output gate signals, which may be received, for example, by a display device.

Abstract: A display panel may include a substrate, pixels, dummy pixels, and voltage lines. The substrate may include a first transmission region for light transmission and/or sound transmission, a non-display area surrounding the first transmission region, and a display area surrounding the non-display area. The pixels may be arranged on the display area and may emit light. The dummy pixels may be arranged on the non-display area, may include a first dummy pixel, and may emit no light. The voltage lines may transmit voltages to the pixels and the dummy pixels. The voltage lines may include a first voltage line and a second voltage line. The first voltage line may be spaced from the second voltage line, may be aligned with the second voltage line, and may overlap the first dummy pixel.

Abstract: A display panel includes a first panel region (FPR) including (n−1)-th and n-th pixel rows ((n−1)PR and nPR), and a second panel region (SPR) dividing the nPR to propagate an optical signal. The display panel includes a circuit element layer (CEL) and a display element layer (DEL). The CEL includes a signal line (SL), a pixel driving circuit (PDC), and first to third regions. The SL and the PDC are in the first region. The second region (SR) corresponds to the SPR. The SL and the PDC are not in the SR. The third region (TR) corresponds to the SPR and is along a periphery of the SR. The SL is in the TR, and includes an (n−1)-th scan line ((n−1)SL) connected to the (n−1)PR, an n-th reset line (nRL) connected to the nPR, and a first row connection line in the TR and connecting the (n−1)SL and the nRL.
