Disclosed is a transparent display device including an electrochromic element. The electrochromic element includes an electrochromic layer, a counter layer, and an electrolyte layer. An image is displayed through an oxidation-reduction reaction, and the display device is in a transparent mode when a voltage is not applied. The electrochromic layer and the counter layer may further include a core material for changing a color at a high speed.

Transparent display device

A reflective display device is disclosed, which includes first and second substrates facing each other, each of which includes a display area and a reflective area; a display element provided in the display area; and a reflective control element provided in the reflective area, controlling reflectance of externally incident light. The reflective display device may improve a contrast ratio by controlling reflectance of a reflective area when an image is displayed.

Reflective display device

Disclosed are a back cover and a transparent display apparatus including the same, in which a chip groove, into which a chip included in a chip-on film coupled to a transparent panel is inserted, is disposed in a rear surface. The transparent display apparatus includes a transparent panel and a back cover. The transparent panel may display an image. The back cover may be transparent, and the transparent panel may be disposed on a front of the back cover. A chip groove into which a chip included in a chip-on film coupled to the transparent panel is inserted may be disposed in a rear surface of the back cover.

Back cover and transparent display apparatus using the same

An organic light emitting display device is disclosed. The organic light emitting display device includes: an organic light emitting display panel defined into a display area for displaying an image and a non-display area surrounding the display area; a chip-on-film loaded with a driver IC chip, which is configured to drive the organic light emitting display panel, and attached to a pad portion which is formed on the non-display area of the organic light emitting display panel; and a printed circuit board configured to apply signals to the driver IC chip and attached to one edge of the chip-on-film, wherein the organic light emitting display panel includes a dummy pad portion which is formed on the non-display area in the same configuration as the pad portion and in opposition to the pad portion.
