An image display including a touch-sensitive display, that creates tactile sensation and movement of an object (3-2) along its surface is provided. Actuators including conductive rods (4-111, 4-112) attached together may be used, such that each rod of the actuator (4-11) may increase or decrease in size when current is applied to that rod to cause the actuator to bend toward a specified direction. Also, an image display that includes ball bearings (1-10) whose rotation is controlled by driving magnets (1-21, 1-22) to cause an object to move is provided. Further, air holes (3-11) tilted in various directions to control object movement by air pressure may be provided. Moreover, rods (3-10) may be moved up or down as activated by driving magnets (2-20). The actuators, rods, ball bearing assemblies, or holes may provide touch sensitivity for the image display.

摘要:
An active matrix display comprises a select driver (SD) to drive select electrodes (SE), and a data driver (DD) to supply data (D) to data electrodes (DE). Pixels (10) are associated with intersections of the data electrodes (DE) and the select electrodes (SE). The pixels (10) comprise a light emitting element (L) and a pixel driving circuit (PD). The pixel driving circuit (PD) receives a power supply voltage (VB) via a power supply electrode (PE), and data (D) via a data electrode (DE) to control a brightness of the light emitting element (L). A power supply (PS) supplies the power supply voltage (VB). The power supply electrodes (PE) are arranged to supply the power supply voltage (VB) to the pixel driving circuits (PD) of lines of pixels (10) extending in the same direction as the select electrodes (SE) or in the same direction as the data electrodes (DE). The load (AL; MA; IL) on the power supply electrodes (PE) caused by the pixels (10) associated with the lines of pixels (10) is determined (LL), and the level of the power supply voltage (VB) is controlled (CO) dependent on the load (AL; MA; IL).
摘要:
An image processing unit (300) for processing an image that is to be displayed in a plurality of sub-fields on a plasma display panel (406), has a storage (304) for storing the set of combinations of sub-fields that are available as intensity levels, and a selector (310) for selecting, from the storage, a particular combination for a pixel to be displayed. The difference regarding sub-fields between a first one of the combinations representing a first available illumination level, and a second one of the combinations representing the next higher illumination level, has been limited, the limiting including control such that only a limited number of the sub-fields that are switched on in the first one of the combinations, are not switched on in the second one of the combinations.
摘要:
Method of calculating new luminance value data based on original luminance value data to be displayed on a matrix display device, where luminance value data are coded in sub-fields, and double-line addressing for the least significant sub-fields is used for reducing the addressing time. A reduction of the difference between the new data and the original data is obtained by computing a new common value for the least significant sub-fields of a set of neighboring or adjacent lines, and new values for the most significant sub-fields of each line of said set of adjacent lines. The method comprises embodiments which are applicable to both binary and non-binary sub-fields.
摘要:
A color display device, a drive circuit for a color display device, a method, a signal and a computer-readable medium for reducing electro-optical cross talk that occurs in a display that is operated in Spectrum Sequential mode is disclosed. The invention eliminates annoying visible artifacts, such as contouring, noise, or color deviation, which normally are introduced by this cross talk by compensating for the cross talk. According to embodiments of the invention, a drive signal (R′,G′,B′) to drive picture elements of the display is altered in video processing circuitry (MPC, XTC, SC) and/or software, in dependence on one or more properties of different spectra from a light source (23, 24) in the display. The invention is implemented with little extra effort and cost in known LCD displays.
