Description

BACKGROUND

Display devices include televisions, laptops, monitors, tablet devices and computers, portable phones, wearable devices, etc. Many, if not all, modern display devices are capable of displaying high resolution images, whether video or still images. Due to encoding limitations and other electrical considerations, such as heat build-up and dissipation or power provision and distribution matters, images may not display with the same effect, either for the image itself or for a user seeing the image, as originally conceived or desired. That is, while the technology for display devices has undoubtedly increased beyond imagination from where it was in the last century, creators and consumers of cinematography and photography may still desire additional capabilities for unique display experiences.

Moreover, as technology for providing the illumination for the display devices improves, changes may be made to deliver a desired image according to the changes in the lighting elements.

Illustrative Embodiments

In an embodiment, a system for energy storage may include a display for smart video/still image playback and/or recording, in which a power supply allows a controller of the display device to overdrive extra power from a power storage unit directly to the lighting elements and/or circuit components connected to the lighting elements. This is done to initiate heightened or enhanced levels of brightness in predetermined scenes or images (e.g., explosions, sunrises, etc.). Such enhanced brightness levels would normally not be possible due to instantaneous power supply limitations from the electric supply available at the primary power source (e.g., a hardwire connected power outlet, a built-in battery, an external battery backup, etc.). The system for energy storage may include: a built-in/internal or an external battery (wired or integrated directly), super capacitors, a secondary power supply source directed to a connected power storage unit, etc. Furthermore, the system may include intelligent control features integrated into the controller that execute steps to deploy the stored energy to ensure that the boosted power is provided whenever enhanced illumination is initiated.

In an embodiment, a system according to the instant disclosure includes a hardware system, a software system, or a combination hardware and software system. The system may be implemented in a display device.

In an embodiment, a display device may include lighting elements and/or circuit arrangements including lighting elements. The lighting elements are configured to, at a predetermined time, receive a boost of energy from an energy storage unit to power the lighting elements and/or circuit arrangements including lighting elements to a level beyond that of the amount of power otherwise available from the primary supply source.

In an embodiment, a display device may include lighting elements and/or circuit arrangements including lighting elements that are configured to, at a predetermined time, receive a boost of stored energy and emit a brightness level greater than the brightness level that is emitted with the use of the lighting elements and/or circuit arrangements when not using the stored energy.

In an embodiment, a display device according to the above description includes portable and stationary televisions, laptops, monitors, tablet devices and computers, portable phones, wearable devices, etc.

In an embodiment, lighting elements are configured to, at a predetermined time, receive a boost of energy from an energy storage unit to power the lighting elements and/or circuit arrangements including lighting elements to a level beyond that of the amount of power otherwise available from the primary supply source.

In an embodiment, a circuit arrangement is configured to, at a predetermined time, receive a boost of energy from an energy storage unit to power lighting elements and/or circuit arrangements including lighting elements to a level beyond that of the amount of power otherwise available from the primary supply source.

In an embodiment, a software update for pre-existing display devices is contemplated to be uploaded to integrate with the control instructions in a pre-existing display device to update the display device to enable lighting elements of the display device to, at a predetermined time, receive a boost of energy from an energy storage unit to power lighting elements and/or circuit arrangements including lighting elements to a level beyond that of the amount of power otherwise available from the primary supply source.

In an embodiment, a software implementation for new display devices is encoded in the control instructions for a newly-manufactured display device to enable lighting elements of the display device to, at a predetermined time, receive a boost of energy from an energy storage unit to power lighting elements and/or circuit arrangements including lighting elements to a level beyond that of the amount of power otherwise available from the primary supply source.

In an embodiment, an external, supplemental battery storage may include one or more processors having instructions stored in a memory associated therewith. The one or more processors may be configured to integrate with a pre-existing display device or a new display device to enhance control of lighting elements of the display device to enable the lighting elements of the display device to, at a predetermined time, receive a boost of energy from an energy storage unit to power lighting elements and/or circuit arrangements including lighting elements to a level beyond that of the amount of power otherwise available from the primary supply source.

As depicted in FIG. 1, a schematic of a system 100 with respect to the function described above according to an embodiment. System 100 may include circuit components and power componentry illustrated, as follows. That is, system 100 may include a rectifier 102 configured to receive AC power. After passing through the rectifier 102, the power may enter a first energy storage 104, which is a standard energy storage for a conventional display device. Power may then pass from the first energy storage 104 to a power regulator 106 before being distributed to through a lighting control 108, which controls the amount of power allotted to various light sources in a lighting module and/or display module 110. Note, FIG. 1 also depicts potential (hence the hashed outlines) additional display components/layers 112 of the lighting module and/or display module 110.

As power from the primary source (AC) is flowing through the system 100, video/data 114 is being received by the central processing unit (“CPU”) 116 for brightness level (“BL”) and display power management. This video/data 114 is filtered through CPU 116 to provide instructions to both the lighting control 108 and the lighting module and/or display module 110 (and potentially to the other display components/layers 112), whereby the correct BL level is displayed.

In the event an enhanced amount of BL is requested in the video/data 114, system 100 may further include a secondary power source 118, such as a battery. Power may be pulled from the secondary power source 118 to a second energy storage 120, such as a capacitor or hybrid capacitor. The power pulled from second energy storage 120 may be passed to the power regulator 106, which then distributes the additional power that had been stored according to the enhanced BL to the lighting control 108, as requested in the signal instructions from the CPU 116.

Thus, system 100 is configured to function such that the additional battery or secondary power source that provides the energy beyond that which is capable of being instantly drawn from the primary source, may be connected to be regulated by the power management control and released depending on the video/data feed to the controller indicating that a surge is requested for a brightness level exceeding that of normal power levels deliverable from the primary source.

For example, (as illustrated in FIG. 2 by the overlaid graphs of power in, from the primary source, brightness level, and power out, from the primary and secondary storage energy available) a TV that is not configured with the features of the instant disclosure may only be capable of providing a power level that allows the light source(s) to produce (e.g., discharge power to cause the light sources to illuminate) a brightness level of 2000 nits (or 200 nits). In contrast, due at least in part to the power supplied by the secondary power supply of the instant disclosure, a TV with such a feature may provide a brightness level of 4000 nits (or 400 nits) or greater. That is, the secondary power boost release may increase the brightness level of the light sources as high as double or more. Although, less than double the brightness may be desirable as well, which may be regulated according to the data received.

FIG. 3 depicts a potential display device, such as a TV. Other display devices are contemplated.
