Problems solved by technology
However, the resolution of transparent display devices may be degraded due to transmissive regions
The problem with transparent display devices is that the higher the resolution, the more the transmittance decreases
In addition, since the transmissive region in the transparent display device increases the separation distance between sub-pixels, the spacing between sub-pixels may be recognized, which may degrade the image quality

Embodiment approach 2
[0115] Embodiment 2 (Case 2) shows an example of a pixel structure disposed over the transparent display panel 110 according to one embodiment of the present disclosure. In Embodiment 2 (Case 2), the arrangement order of sub-pixels is different in the pixels provided on the first signal line SL1-1 in odd rows and the pixels provided on the first signal line SL1-2 in even rows.
[0116] In this case, pixels arranged in the first signal line SL1-1 of odd rows may be arranged so that two red subpixels may face each other above the second signal line SL2, and the green subpixel and the blue subpixel may face each other. The sub-pixels may face each other over the odd-numbered rows of the first signal line SL1-1.
[0117] Pixels arranged in the first signal line SL1-2 of the even-numbered row may be arranged such that one of the two red sub-pixels may face the green sub-pixel above the first signal line SL1-2 of the even-numbered row, while two Another one of the red sub-pixels ma...

Abstract
A transparent display device. The transparent display device may have high transmittance while achieving high resolution. In addition, the transparent display device can provide optimal image quality. The transparent display device includes: a plurality of first signal lines extending in a first direction and spaced apart from each other; a plurality of second signal lines extending in the second direction and spaced apart from each other; a transmission area arranged between the two first signal lines and the two second signal lines which are adjacent to each other; and a pixel disposed in an intersection region where the first and second signal lines intersect each other, the pixel including a first sub-pixel emitting light of the first color, a second sub-pixel emitting light of the second color, and a third sub-pixel emitting light of the third color. The pixels include first pixels overlapping a portion of the first signal lines of the odd-numbered rows and second pixels overlapping a portion of the first signal lines of the even-numbered rows, the first and second pixels being different from each other in position of at least one of the first, second, or third sub-pixels.
Description
technical field [0001] The present disclosure relates to a transparent display device. Background technique [0002] With the advancement of the information society, demands for display devices that display images are increasing in various forms. Recently, various display devices such as liquid crystal display (LCD) devices, plasma display panel (PDP) devices, organic light emitting display (OLED) devices, quantum dot light emitting display (QLED) devices, etc. have been widely used. [0003] Recently, research on transparent display devices is being actively conducted to allow users to view objects or images arranged on opposite sides of the display device behind the transmissive display device. [0004] The transparent display device may have high light transmittance in the display area through the transmission area. However, the resolution of the transparent display device may be degraded due to the transmissive area. A problem with transparent display devices is that ...
