Abstract
A display apparatus is provided. The display apparatus includes a display panel, a first layer, a signal applying unit, and a controller. The display panel displays an image. The first layer is formed on a first surface of the display panel. A shape of the first layer is changed when a first signal is applied to the first layer. The signal applying unit applies the first signal to the first layer. The controller controls the display panel to display the image.
Claims18
A display apparatus comprising:
- a display panel comprising a plurality of pixels configured to emit a light to display an image;
- a first layer formed on a first surface of the display panel, a surface roughness of the first layer being changed at a first area when a first signal is applied to the first layer, the surface roughness of the first layer being changed such that the first layer transitions from being flat to having continuous peaks and valleys in the first area, wherein heights of the peaks and depths of the valleys are adjustable based on texture information of the image, wherein a width of the first area where the first layer has the continuous peaks and valleys is the same as a width of the first signal at the first area, and wherein the first signal is different from the light emitted from the plurality of pixels;
- a signal unit including a plurality of control elements wherein a first control element of the plurality of control elements generates the first signal, the first control element being sandwiched between adjacent pixels of the plurality of pixels;
- and
- a controller controlling the display panel to display the image in response to an image signal and controlling the signal unit in response to a surface adjust signal, wherein all the pixels remain fixed in position when the surface roughness of the first layer is changed, and
- wherein the pixels are controlled to display the image according to the image signal and the first control element is controlled to change the surface roughness of the first layer according to the surface adjust signal, the surface adjust signal being based on a texture represented by the image at the first area.

- a first layer formed on a first surface of the display panel, a surface roughness of the first layer being changed at an area when a first signal is applied to the first layer, the surface roughness of the first layer being changed such that the first layer transitions from being flat to having continuous peaks and valleys in the area, wherein heights of the peaks and depths of the valleys are adjustable based on texture information of the image, wherein a width of the area where the first layer has the continuous peaks and valleys corresponds to a width of the first signal applied to the first layer, and wherein the first signal is based on a texture represented by the image in the area and is different from the light emitted by the plurality of pixels;
- and
- a plurality of control elements applying the first signal to the first layer, at least one of the control elements being sandwiched between adjacent pixels of the plurality of pixels,
- wherein the plurality of control elements includes at least one of a light source, a heat source, or an electrode,
- wherein all the pixels remain fixed in position when the surface roughness of the first layer is changed,
- wherein when the texture represented by the image in the area corresponds to a rough texture, the surface roughness of the first layer is increased with respect to a value near zero,
- when the texture represented by the image in the area corresponds to a soft texture, the surface roughness of the first layer is decreased with respect to the surface roughness of the first layer when the texture represented by the image in the area corresponds to the rough texture, and
- when the texture represented by the image in the area corresponds to a smooth texture, the surface roughness of the first layer is adjusted to have the value near zero.
