Disclosure is an ink supply system for an ink-jet head with a steam cleaning function. The ink supply system includes an ink-jet head including a nozzle, an ink storing device, a gas pressure control system applying negative or positive pressure to the ink storing device, a cleansing solution storing part, and a steam generating device changing at least a part of the cleansing solution into steam, wherein the cleansing solution or the cleansing solution steam is inserted into the ink storing device to clean the ink storing device and the ink-jet head. The ink supply system cleans quickly and completely residue of ink to prevent contamination during the process of changing and using ink, and the ink storage, the ink-jet head, and the ink flow path are cleaned by evaporated cleansing solution during long-term printing, thereby maintaining the ink-jet head and the ink supply system into the initial state.

A display device includes a display module, a window disposed above the display module, an optical film disposed between the display module and the window, an adhesive layer, and a refractive index matching pattern. The window includes a base substrate and a bezel pattern overlapping with the base substrate and defining a first transmissive area and a second transmissive area isolated from the first transmissive area in a plane view. The optical film includes a first open area defined therein to correspond to the second transmissive area. The adhesive layer couples the window with the optical film. The refractive index matching pattern is disposed in the first open area and has a refractive index of about 90% to about 110% of the adhesive layer. The first open area is defined as an area in which the optical film is not disposed.

Display device and electronic device having the same

A curved display device including a display substrate, an opposite substrate, a liquid crystal layer, a pixel electrode, a common electrode, and a light blocking layer. The display substrate includes pixel areas included in a display area, and is curved along a first direction. The opposite substrate faces the display substrate and is coupled to the display substrate to be curved together with the display substrate. Domains are defined in each pixel area and arranged in a second direction crossing the first direction. Liquid crystal molecules in a first set of two domains, which are sequentially arranged and disposed adjacent to the light blocking layer, are aligned toward a first side of the display area, and liquid crystal molecules in a second set of two domains facing the first set of two domains are aligned toward the second side of the display area.

A display device includes a plurality of pixel rows, a first data line, a second data line, a data driver, a first test part, and a second test part. Each of the plurality of pixel rows includes a plurality of pixels. The first data line is disposed between two adjacent pixel rows among the a plurality of pixel rows. The second data line is disposed between the two adjacent pixel rows. The data driver is configured to provide at least one data signal to the first data line and the second data line. The first test part is connected to one of the first data line and the second data line, and is disposed between the plurality of pixel rows and the data driver. The second test part is electrically connected to the other of the first data line and the second data line.

Display device

Curved display device having domains of liquid crystal molecules aligned in different directions

A curved display device includes a display panel and members to curve the display panel in a first direction. The display panel includes a display substrate and a counter substrate. The display substrate comprises a pixel electrode disposed on a display area and in which first slits are formed, and the counter substrate comprises a common electrode facing the pixel electrode and in which second slits are formed. A first side area, a central area and a second side area are sequentially located in the first direction on the display area. When the display panel has a flat shape, a portion of the common electrode positioned between two adjacent second slits among the second slits overlaps the pixel electrode by an overlapping width. The length of the overlapping width in each of the first and second side areas is different from that of the overlapping width in the central area.

Curved display device

A curved display device includes a display panel having a display area on which an image is displayed; a receiving member receiving the display panel; and a cover member covering a border of the display panel to combine with the receiving member. The display panel has a bent shape along a first direction and a second direction crossing the first direction and each of the receiving member and the cover member is bent to maintain the bent shape of the display panel.
