A haptic display includes at least one haptic device that can give tactile feedback instead of visible feedback. Each of the haptic devices converts a signal from a signal producing unit into force or tactile pattern. The haptic device does not require a large mass, so that it can be provided on almost any portion or part within the body of a mobile apparatus. For example, the haptic device can be embedded under a touch panel display that constitutes both input and output device. By providing the haptic devices under respective menu/function button areas displayed on the touch panel display, it is possible to stimulate the specific button in response to the user-input-operation, thereby directly providing the tactile feedback to the user's finger touching the corresponding button.

A method and system for creating an object or character in a drawing window and simultaneously displaying the object or character in animated form wherein the animated form is available for instant playback or feedback to the user is described. A single process is used for creating the object and animating the object. The user is able to draw the object in a drawing window and have the object animated in an animation window as the object is being drawn, thereby allowing the user to immediately see the results of the animation.

When an organic EL display apparatus enables display of a standard luminance mode and a high luminance mode, it takes long time to reset the gate potential of the OLED drive TFT to a given value in a standard mode. In the reset operation of the gate potential of an OLED drive TFT at the time of writing an image signal, in a standard mode, a precharge current is allowed to flow in the OLED element for a short period before the reset operation to set an initial value of the gate potential of the OLED drive TFT to be close to a supply potential or a reference potential. With the above operation, the variation of the OLED drive TFT gate potential after resetting is reduced. As a result, the light emitting period during one frame can be extended. Also, since a blanking period can be extended, it is possible to measure the characteristic of the OLED element by using the blanking period.
