Description

METHODS OF CREATING AND USING TRADEABLE CARBON CREDITS WITH DISPLAY DEVICES
FIELD
This invention relates to methods of creating and using tradeable carbon credits with display devices and to display kits useful in carrying out the methods.
BACKGROUND
Due to global climate change, companies and individuals are looking for ways to reduce or offset carbon use or footprint. Carbon cap and trade systems are one mechanism available for reducing or offsetting carbon use. Carbon cap and trade systems allow for the purchase or trade of “carbon credits,” which are generated by energy savings and verified by an independent agency. The producer of the generated carbon credit may sell the carbon credit as a commodity or “retire” the credit in their name to reduce their carbon footprint.
Many carbon credits are generated by small, local community programs with projects such as enhancing forests, building more efficient cook stoves, and wildlife restoration projects. More recently, larger companies have become involved in creating carbon credits through energy savings from more efficient water heaters, electric vehicles, building construction and other products. Some companies rely on purchasing carbon credits to reduce their carbon footprint.
SUMMARY
The generation of tradeable carbon credits incentivizes the creation and use of energy saving products and technologies.
The use of consumer electronics and other display devices has dramatically risen in recent years. To reduce energy consumption, particularly residential electricity consumption, it is critical that consumer electronics are designed and built for energy efficiency.
In view of the foregoing, we recognize that a method for creating and using tradeable carbon credits with display devices is needed.
Briefly, in one aspect, the present invention provides a method for creating and using tradeable carbon credits with display devices. The method comprises the steps of: (a) identifying a display component that provides greenhouse gas emission reductions in a display device while the display device is powered; (b) obtaining certification of tradeable carbon credits for greenhouse gas emissions reductions provided by the display component when the display device is powered; (c) providing the display component for use in a display device; and (d) receiving tradeable carbon credits over the course of the lifetime of the display device. In another aspect, the present invention provides a display kit comprising (a) a display device comprising a display component that provides greenhouse gas emission reductions while the display device is powered; and (b) a consumer disclosure comprising a statement that tradeable carbon credits will be generated by use of the display device.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a flowchart illustrating the method of the invention.
FIG. 2 illustrates an example method of the invention.
DETAILED DESCRIPTION
The present invention relates to a method for creating and using energy credits with display devices such as televisions, monitors, laptop computers, tablets, mobile phones, automotive displays and the like utilizing a display component that makes the display device more energy efficient. In some embodiments, the display device is a high transmission display or a high color gamut display.
FIG. 1 is a flow chart that generally illustrates an embodiment of the method of the invention. Any or all of the steps in the method may be performed by any entity in order to carry out the method. The method is typically, but not necessarily, carried out in the order shown in FIG. 1
The method typically begins by identifying a display component that provides greenhouse gas emission reductions in a display device while the device is powered (110). As used herein, a display component “provides greenhouse gas emission reductions in a display device while the device is powered” if a display device comprising the display component can deliver equivalent (or increased) luminance or color gamut as the same display device without the display component (a “conventional display”) at a given (or reduced) power usage. In some embodiments, the display component can reduce energy consumption by more than 10%, 20%, 30% or 40%.
The luminance of a display can be measured using a luminance meter or calibrated camera system. Power consumption of a device containing a display can be measured using a wall-plug power meter. Methods for repeatably measuring both luminance and power properties of a television, e.g., are well established and codified in the Federal Registrar (Title 10 / Chapter II / Subchapter D / Part 430 / Subpart B / Appendix H: Uniform Test Method for Measuring the Power Consumption of Television Sets). In addition to the Federal Trade Commission’s Energy Guide Label, these same methods are used by the EPA in determining whether a product qualifies for an ENERGY STAR designation. For the purposes of establishing greenhouse gas emission reduction enabled by a display device, these methods can be used. Other methods can also be used if they are self-consistent such that valid comparisons can be made with and without the display component under investigation.
Any suitable display component that reduces the power required for display devices can be utilized in the methods of the invention. Examples include optical fdms, optically clear adhesives, light guides and other optical structures, light sources, heat dissipation components and like.
Optical fdms include, e.g., reflective fdms, diffusion fdms, prism fdms, lens fdms, antireflection fdms, light control fdms (e.g., micro-louver fdms) and polarizing fdms. Typically, optical fdms are utilized for energy efficiency in liquid crystal displays (LCDs) but they may be utilized in organic light emitting diode (OLED) displays or any other type of display. LCDs use a backlight unit placed behind the liquid crystal panel for illumination. To enhance the efficiency of the backlight system, optical fdms can be used for light recycling.
Optical fdms such as quantum dot enhancement fdms (QDEF) and color filters can be utilized to efficiently improve color gamut in LCDs. The term color gamut describes the pallet of colors encompassed by a standard or that given display can represent. A spectrometer can be used to measure the color spectrum. The color gamut of a display can be calculated by measuring the x, y value of its full red, green and blue colors and then calculating the area within. The color gamut of a display is typically described by its relation to standard color gamuts. The color gamuts of high performance displays are usually described in terms of Adobe RGB or Digital Cinema Initiatives (DCI) P3 standards. A display equipped with QDEF can express a color gamut using a more transmissive color fdter. Less light is needed from the backlight unit to achieve the desired display brightness, so less energy is consumed. For example, a 100% DCI-P3 display with QDEF, has better energy efficiency than a 100% DCI-P3 display without QDEF.
Prism films can be utilized to recycle and redirect light to manage the angular output from the backlight, increasing brightness. Examples of commercial prism films include 3M™ Brightness Enhancement Film (3M BEF), Thin Brightness Enhancement Film (3M TBEF) and Advanced Structured Optical Composite (3M ASOC), all available from 3M Company, St. Paul, MN.
Reflective polarizers recycle and recover light that is normally absorbed by the panel to increase the light transmitted to the viewer. Reflective polarizers include, e.g., polymer fibers within a polymer matrix, polymer dispersed-reflective polarizers and polymeric multilayer optical film (MOF) reflective polarizers. In some embodiments, MOF reflective polarizers can increase the amount of light transmitted to a viewer by 30 - 40% or more . Examples of MOF reflective polarizers include 3M™ Dual Brightness Enhancement Film (3M BEF) and Advanced Polarizer Film (3M APF). 3M APF is applied directly to the panel. Reflectors and reflective films such as white reflectors, silver reflectors and enhanced specular reflectors (e.g., 3M™ ESR, a MOF reflective film) can be utilized to optimize light recycling in the backlight.
Multifunctional films can also be utilized to perform multiple jobs. For example, 3M™ Brightness Enhancement Film Reflective Polarizer (3M BEFRP) combines the functions of a prism film and a reflective polarizer film into a single backlight film.
After a suitable display component is identified, certification for tradeable carbon credits for greenhouse gas emissions reductions provided by the display component when the display device is powered can be obtained (120). As used herein, the term “tradeable carbon credit” means a certificate showing a reduction or offset of greenhouse gas emissions which can be traded at their current market price. In order to obtain a tradeable carbon credit, a reduction of measurable emissions must be demonstrated.
Any suitable verification program may be utilized. One exemplary program or methodology that can be used for verifying tradeable carbon credits is the Verified Carbon Standard (VCS) Program, which is administered by Verra. Projects can be issued tradable carbon credits called Verified Carbon Units (VCUs), which can then be sold on the open market and retired by individuals and companies as a means to offset their own emissions.
To determine if a television is considered eligible for carbon credits, there are certain criteria that must be met depending on the methods used in the verification process. One method to determine if televisions are eligible is to take the annual kWh divided by the screen area.
Tradeable carbon credits are based on energy savings from a device and regional power generation. Regional CO2 emission data can be found from source such as U.S. Energy Information Administration. For example, emission data can be based upon a country average, region average or state average. CO2 emissions vary depending on the source of electricity generation such as, e.g., from coal or nuclear generation.
The display component can be provided for use in a display device (130) so that tradeable carbon credits are received over the course of the lifetime of the display device (140).
Providing the display component for use in a display can comprise selling the component or providing it for free. The component can be sold, e.g., at a reduced price (compared to a component not certified for tradeable carbon credits.). The manufacturer or distributor of the display component may provide the component with rebates or other incentives or for free or at a reduced price because the manufacturer or distributor can, in some embodiments of the invention, receive the tradeable carbon credit from the user of the display device.
The tradeable carbon credits go to whomever utilizes the display device and has actual power savings. Typically, this is a consumer. The consumer cannot easily trade the resulting tradeable carbon because costly accounts and registrations are required. Thus, the tradeable carbon credit is not valuable to the typical consumer. Thus, in some embodiments of the method of the invention, the consumer forfeits or reassigns the tradeable carbon credit to the manufacturer of distributor of the display component. The display device can be sold to the consumer with a disclosure of the tradeable carbon credits generated by the display device and agreement of forfeiture of the tradeable carbon credits. This disclosure can be accomplished by any effective means. For example, the disclosure may be printed on packaging, a warranty card, an insert or the like. The printing may include the complete notice and forfeiture language. Alternatively, the complete disclosure may be provided via a QR code or a website notification
In some embodiments of the method of the invention, a project funder can be utilized to implement a tradeable carbon credit project where, e.g., a display integrator or manufacturer is paid for utilizing the display component. The manufacturer of the display component sells more components, the display integrator or manufacture is incentivized to use the energy efficient display component and the project funder acquires carbon credits that can be sold.
Objects and advantages of this invention are further illustrated in FIG. 2 by an example wherein the display component is a reflective polarizer and the display device is a television. The particular conditions and details of this example should not be constmed to unduly limit this invention.
A manufacturer of MOF reflective polarizer (202) provides the MOF reflective polarizer (204) to a display integrator (206) who incorporates the MOF reflective polarizer into an LCD television (208). An LCD television that does not include MOF reflective polarizer is not as efficient as an LCD television that uses MOF reflective polarizer.
The LCD television (208) is sold by the integrator (206) to a consumer brand (210), who then sells the television (208) to a retailer (212). The retailer (212) sells the television to a consumer (214). The consumer (214) plugs in the television (208) and utilizes electricity (216) generated by a power company (218). The power company (218) creates CO2 emissions (220) when generating power. However, due to the incorporation of MOF reflective polarizer in television (208) less electricity is utilized to power television (208) than a conventional television. Thus, a CO2 savings (222) is “created.” The CO2 savings (222) can be verified (230) as a tradeable carbon credit.
For example, a 55” LCD television that does not include MOF reflective polarizer (a “conventional” television) will require 162 watts of electricity to achieve 600 nits of luminance. The same LCD television with MOF reflective polarizer will require only 120 watts of electricity to achieve 600 nits of luminance. The energy saved per television is 42 watts. If a television is in use for 5 hours per day, 365 days per year and has a lifetime of 10 years, the total energy saved would be 766 kWh over the lifetime of the television. Sources such as the United States Environmental Protection Agency (U.S. EP A) can provide conversion for the national averages of kWh to CO2-C. In this example the 766kWh can be converted to 0.542 metric tons of CO2 saved by using a MOF reflective polarizer. This reduction in greenhouse gas emission can be verified and certified as a tradeable carbon credit.
The CO2 credit (223) goes to the consumer (214), who assigns it to the brand (210), as one of the participants in this supply chain includes a consumer disclosure of the tradeable carbon credits generated by the television and a reassignment or forfeiture of the tradeable carbon credits. Per an agreement between the brand (210) and the manufacturer (202), the brand assigns the CO2 credit to the manufacturer. The manufacturer (202) then has three options: (1) sell the CO2 credit to another company (224), who retires the credit in that company’s name; (2) sell the CO2 credit (223) to a broker (226) who sells the credits to another company (228), who retires the credits in their name; or (3) retire the credits in manufacturer’s own name.
Various modifications and alterations to this invention will become apparent to those skilled in the art without departing from the scope and spirit of this invention. It should be understood that this invention is not intended to be unduly limited by the illustrative embodiments and examples set forth herein and that such examples and embodiments are presented by way of example only with the scope of the invention intended to be limited only by the claims set forth herein as follows.
