摘要:
A device for controlling a display with a number of strings of light-emitting elements (particularly bulbs) connected in series to offer a aesthetically favorable jeu de lumiere, having, apart from a timing generator and a driving circuit for the display, a read only memory ROM, a programmable logic array PLA, two dividers and two address counters. With this device, all the aesthetically practical patterns can be repeated in desired times with varying speeds while requiring a very small storage capacity of the ROM, thus considerably saving the cost of production.

The present invention relates to an electronic sign with a number of light bulbs provided in rows and columns (so called matrix), whereby said bulbs (L) are turned on row by row or column by column (so called multiplex operation). For increasing the life of the bulbs (L), said bulbs (L) are operated by alternating current at high frequency.

A display system utilizing incandescent lamps arranged at the intersection points of a matrix array of row and column conductors includes a plurality of load resistors connecting the row conductors to a first voltage source and a plurality of load resistors connecting the column conductors to a second voltage source. To energize a selected lamp, the row conductor connected to that lamp is connected to the second voltage source and the column connected to that lamp is connected to the first voltage source.

A memory and driver circuit for each lamp of a flat screen video display apparatus which comprises a plurality of addressable incandescent lamps arranged in an X-Y matrix is provided. The gray scale visual effect of the video information being presented comes as a result of controlling the length of time of illumination of each lamp. Each of the lamps is connected in series with a source of power and a switchable solid state device such as an SCR or a transistor. When the source of power is an alternating current source where each of the pulses has its initial slope always in the same sense with respect to zero, the circuit is arranged with negative-going video information so that the lamps are held off -- i.e., black -- in the presence of a video signal above a threshold, and are thereafter turned on. Phase modulation is thereby provided. When the source of power is direct current, each lamp is illuminated when there is a video signal intended for that lamp and above a predetermined reference level. Pulse width modulation is provided in this case.

It is provided a method for displaying content on a screen where light intensity of each pixel of the screen is adjustable. The method comprises steps of receive a touch of a touching object on the screen; and adjusting light intensity so as to make surrounding pixels of a contact point between the touching object and the screen have a higher intensity and rest pixels have no light intensity or a lower light intensity, wherein, the lower light intensity enables content displayed on corresponding pixels perceptible to a user.

Techniques are disclosed for providing a color pattern unlock mode in electronic touch sensitive devices. The color pattern unlock mode can display an unlock screen to the user, prompting the user to arrange or create a specific color pattern in order to unlock the device. The customizable color pattern may include any uniquely identifiable unlocking pattern including a combination of colors. Example color patterns include a combination of colors arranged in a certain order, a combination of colors combined with a password, a combination of colors combined with one or more words written out in one or more colors, or a combination of colors each matched with a specific image. When the user has arranged the proper color pattern, the device unlocks and may be used. If the correct color pattern is not arranged, the device remains locked.

An incandescent light source display includes a substrate, a plurality of first electrode down-leads, a plurality of second electrode down-leads and a plurality of heating units. The plurality of first electrode down-leads are located on the substrate in parallel to each other and the plurality of second electrode down-leads are located on the substrate in parallel to each other. The first electrode down-leads cross the second electrode down-leads and corporately define a grid having a plurality of cells. Each of the incandescent light sources is located in correspondence with each of the cells. Each incandescent light source includes a first electrode, a second electrode and an incandescent element. The incandescent element includes a carbon nanotube structure.

A portable music player apparatus that outputs visual content to a head-worn transmissive display, the visual content being modulated in time with playing musical content and overlaid upon the user's direct view of his or her physical surroundings. In this way, the user is provided with an enhanced visual view of his or her physical surroundings, the enhanced visual view including transmissive visual content that is generally synchronized in time with the playing music content. This provides the user with an improved music listening experience in which he or she feels present within a visually enhanced version of the physical world that has changing visual qualities that are perceptually synchronized in time with one or more features of the playing music. The displayed visual content may include time-varying translucency and/or color-tinting such that the user's direct view of the physical world changes in brightness and/or color tinting in a manner choreographed with the playing music.
