Description

[Technical Field]

[0001] The present disclosure relates generally to display technology, and more particularly to integrating grayscale content with injected color in transflective systems. [Background technology]

[0002] In the field of display technology, there are various display devices, each with its own unique characteristics. Liquid crystal displays (LCDs) and organic light-emitting diode (OLED) displays are known for their ability to display a wide range of colors, providing vivid and dynamic images. On the other hand, reflective displays create images by reflecting ambient light. These displays are known for being power efficient and easy to view, even in bright light. However, reflective displays have traditionally been limited to monochromatic or black-and-white images. Now, with the advancement of display technology, attempts are being made to combine the advantages of these different types of displays to create more versatile and efficient display devices. Summary of the Invention [Problem to be solved by the invention]

[0003] The present disclosure provides a display device having color information injected into monochrome visual information using a spatially addressable backlight generator in a system employing a transflective spatial light modulator. Existing display technologies have several limitations. For example, color displays such as LCDs and OLEDs can provide vivid and dynamic images, but they consume a lot of power and can be difficult to view in brightly lit areas. On the other hand, reflective displays may be more power efficient and easier to view in brightly lit areas, but are generally limited to monochrome images. This limitation can limit the use of reflective displays in applications where color information is important. [Means for solving the problem]

[0004] Implementations described herein address these and other drawbacks through a display device that includes a monochrome image generating device and a spatially addressable backlight generator. The monochrome image generating device may generate monochrome visual information for display, while the spatially addressable backlight generator may inject color light into the monochrome visual information, such that the injected color information is presented on a display surface. This may enable the display device to present color information while maintaining the power efficiency and visibility advantages of a reflective display.

[0005] One aspect of the present disclosure relates to a display device. The display device may include a display surface, a monochrome image generating device, a spatially addressable backlight generator, and one or more processors. The monochrome image generating device may be configured to generate monochrome visual information for display on the display surface. The monochrome image generating device may reflect light from a primary light source using a transflective spatial light modulator. The spatially addressable backlight generator may be configured to backlight the transflective spatial light modulator. The spatially addressable backlight generator may include a color light source array selectively driven to emit light toward a non-reflective side of the transflective spatial light modulator, thereby injecting color light into the monochrome visual information generated by the monochrome image generating device, so that the injected color information is presented on the display surface along with the monochrome visual information. The one or more processors may be configured to determine the injected color information to be presented on the display surface and control the color light sources in the spatially addressable backlight generator to emit light toward the non-reflective side of the transflective spatial light modulator, enabling the presentation of the injected color information.

[0006] According to some implementations, the one or more processors may be further configured to control the monochrome image generating device to generate monochrome visual information for display on the display surface.

[0007] According to some implementations, the one or more processors may be further configured to obtain presentation information defining visual information for presentation on the display surface, the presentation information defining the visual information in terms of color, determine from the presentation information monochrome visual information for generation by the monochrome image generation device, and determine from the presentation information injected color information.

[0008] According to some implementations, the monochromatic visual information displayed on the display surface may have higher resolution than the injected color information presented on the display surface.

[0009] According to some implementations, the monochrome image generating device can generate monochrome visual information to be displayed on the display surface at a resolution at least 100 times higher than the highest resolution of injected color information that the spatially addressable backlight generator can generate on the display surface.

[0010] According to some implementations, the color light source may include a side-mounted LED.

[0011] According to some implementations, the side-mounted LEDs may include LEDs that emit light of one of at least three different colors.

[0012] According to some implementations, the transflective spatial light modulator may have a physical passage formed between the non-reflective side and the reflective side through which colored light generated by the spatially addressable backlight generator passes, injecting colored light into monochrome visual information.

[0013] According to some implementations, the transflective spatial light modulator may include a transflective liquid crystal device.

[0014] According to some embodiments, the one or more processors may be further configured such that the determination of the injected color information is based on user interaction with monochromatic visual information displayed on the display surface.

[0015] According to some implementations, the spatially addressable backlight generator may include a transmissive liquid crystal device.

[0016] Another aspect of the present disclosure relates to a method for using a display device. The method may include receiving input data. The method may include processing the input data using one or more processors of the display device to determine monochromatic visual information and injected color information. The method may include controlling a monochromatic image generating device of the display device to generate monochromatic visual information for display on a display surface of the display device. The method may include controlling a spatially addressable backlight generator of the display device to backlight a transflective spatial light modulator of the monochromatic image generating device. The spatially addressable backlight generator may include an array of color light sources driven to selectively emit light toward a non-reflective side of the transflective spatial light modulator, thereby injecting color light into the monochromatic visual information, such that the injected color information is presented along with the monochromatic visual information on the display surface. The method may include presenting the injected color information and the monochromatic visual information on the display surface.

[0017] These and other features and characteristics of the present technology, as well as the method of operation and function of associated structural elements, combination of parts, and economies of manufacture, will become more apparent from a consideration of the following description and appended claims, taken in conjunction with the accompanying drawings, all of which form a part of this specification, and like reference numerals indicate corresponding parts in the various drawings.

[Figure 2] 1 illustrates an example of presenting monochromatic visual information along with injected color information on a display surface, according to some implementations. [Figure 3] FIG. 1 illustrates an example implementation of a spatially addressable backlight generator, according to some implementations.

[Figure 5] FIG. 1 illustrates an exemplary method for using a display device, according to some embodiments. DETAILED DESCRIPTION OF THE INVENTION

[0019] In some implementations, a display device may be used that includes a display surface. The display surface may be an area on which an image or information is displayed. The display surface may be made of various materials and may be any size depending on the specific implementation. The device may include a monochromatic image generator designed to create monochromatic visual information for display on the display surface. Monochromatic visual information refers to images or information displayed in one color or shades of one color. This may be particularly useful in situations where color is unnecessary or may be distracting.

[0020] Monochromatic image generating devices may use transflective spatial light modulators to reflect light from a primary light source. The primary light source may be the main light source for the display device. The primary light source may include ambient light and / or other light sources. A transflective spatial light modulator is a device that can both transmit and reflect light, allowing the amount and direction of light that passes through to be controlled. This may be particularly useful for controlling the brightness and contrast of a displayed image.

[0021] The display device may include a spatially addressable backlight generator. The backlight generator may be designed to backlight the transflective spatial light modulator. Backlighting refers to the process of illuminating a display from behind, which may enhance the visibility of the displayed image. The backlight generator may include an array of color light sources that can be controlled to selectively emit light toward the non-reflective side of the transflective spatial light modulator. These color light sources may be of any type suitable for a specific implementation, such as LEDs. These color light sources can emit light of various colors, which can be used to add color to a monochromatic image.

[0022] This may enable the device to inject color light into the monochromatic visual information generated by the monochromatic image generating device. Injecting color light may refer to the process of adding color by illuminating a monochromatic image with color light. This may be done in a controlled manner to achieve a desired visual effect. As a result of this color light injection, the injected color information may be presented on a display surface along with the monochromatic visual information. Injected color information refers to color elements added to a monochromatic image. This may enhance the visual beauty and visual information content of the displayed image.

[0023] The display device may include one or more processors. These processors may be configured to determine injected color information for presentation on the display surface. The processor may be of any type suitable for a particular implementation, such as a microprocessor. The processor may perform a variety of tasks, including processing the visual information to be displayed. This means that the processor may control which parts of an image are colored and which colors are used. This may allow for a high degree of customization and flexibility in displaying images.

[0024] The processor may be configured to control color light sources within the spatially addressable backlight generator. The processor may direct these light sources to emit light toward the non-reflective side of the transflective spatial light modulator. This may enable the processor to control the injection of color light into monochromatic visual information, thereby enabling the presentation of injected color information. Enabling the presentation of injected color information may refer to the process of representing color elements on the display surface. This process may include various steps, including controlling the color light sources and the transflective spatial light modulator.

[0025] In summary, some implementations include display devices capable of presenting monochromatic images with selectively colored elements. This means that the display device can show an image that primarily uses one color, but certain portions use a different color. This can be achieved by using a monochromatic image generating device, a spatially addressable backlight generator with color light sources, and one or more processors that control the generation and presentation of the injected color information. This can result in images or information being displayed in a unique and visually pleasing way.

[0026] FIG. 1 is a schematic diagram of an exemplary display device 100 according to some implementations. The display device 100 may be part of a larger system, such as a computer or mobile device. The display device 100 may be designed to present visual information to a user in a clear and efficient manner. As shown in FIG. 1 , the display device 100 may include one or more of a display surface 102, a monochrome image generating device 104, a primary light source 106, a transflective spatial light modulator 108, a spatially addressable backlight generator 110, a color light source array 112, one or more processors 114, and / or other components. Each of these components may contribute to the overall functionality of the display device 100. These components may work together to generate and present visual information to a user.

[0027] Display surface 102 may be the primary interface of display device 100. This means that display surface 102 may be the part of display device 100 with which a user interacts most directly. Display surface 102 may be configured to present visual information to a user. This visual information may be generated by other components of display device 100. The visual information may include text, images, video, and / or other types of content. This content may be generated by other components of display device 100. Content may be presented in a variety of formats, including still images, moving images, and interactive content. Display surface 102 may be made from a variety of materials, including, but not limited to, glass, plastic, and / or other suitable materials. These materials may be selected based on a variety of factors, including durability, cost, and visual clarity.

[0028] The monochrome image generating device 104 may be configured to generate monochrome visual information for display on the display surface 102. The monochrome visual information may include monochrome images or text. The color may be black, white, or any other color. The monochrome image generating device 104 may include a transflective spatial light modulator 108. The primary light source 106 may be ambient light and / or other light sources. The transflective spatial light modulator 108 may be a device that modulates the light to create monochrome visual information. Light emitted from the primary light source 106 toward the transflective spatial light modulator 108 may be modulated by the transflective spatial light modulator 108 to generate monochrome visual information. The transflective spatial light modulator 108 may selectively reflect light from the primary light source 106 back toward the display surface 102 across an array of discrete locations. The light received from the primary light source 106 may be a specific color or wavelength, or may include light having a spectrum of wavelengths, such as in implementations where the primary light source 106 is ambient light. The transflective spatial light modulator 108 can then modulate this light to create monochrome visual information.

[0029] The transflective spatial light modulator 108 may be configured to modulate the light received from the primary light source 106. Modulation may include changing properties of the light, such as intensity or color. This may be done to create monochromatic visual information. The transflective spatial light modulator 108 may include a non-reflective side and a reflective side. These non-reflective and reflective sides may each have different properties and may interact with the light from the primary light source 106 in different ways. The non-reflective side may be configured to receive the light from the primary light source 106, while the reflective side may be configured to reflect the modulated light toward the display surface 102. The non-reflective side may absorb a portion of the light from the primary light source 106, while the reflective side may reflect the remaining light toward the display surface 102. This reflected light may form the monochromatic visual information presented to the user.

[0030] The spatially addressable backlight generator 110 may be configured to backlight the transflective spatial light modulator 108. Backlighting may include providing light from behind the transflective spatial light modulator 108, which may enhance the visibility of monochrome visual information. The spatially addressable backlight generator 110 may include a color light source array 112. This array may be composed of multiple light sources, each of which may emit light of a different color. The color light source array 112 may be driven to selectively emit light toward the non-reflective side of the transflective spatial light modulator 108. This may include illuminating specific light sources in the array based on the visual information to be presented. This may inject color light into the monochrome visual information generated by the monochrome image generating device 104, thereby presenting the injected color information on the display surface 102. The injected color information may be a combination of the monochrome visual information and color light from the color light source array 112. This may achieve a vivid and colorful display.

[0031] The one or more processors 114 may be configured to determine the injected color information for presentation on the display surface 102. This may include processing visual information generated by other components of the display device 100. The processor 114 may use an algorithm or other calculation method to determine the injected color information. The one or more processors 114 may also be configured to control color light sources within the spatially addressable backlight generator 110 to emit light toward the non-reflective side of the transflective spatial light modulator 108. This may include sending signals to the color light sources to turn them on or off or to change their color or intensity. This may enable the injected color information to be presented on the display surface 102. The injected color information may be presented in a manner that is clear and pleasing to the user. This presentation may be controlled to optimize the visibility and clarity of the visual information.

[0032] 2 illustrates an example of presenting monochromatic visual information 202 along with injected color information 204 on a display surface 200, according to some implementations. Display surface 200 may be part of a display device such as a monitor, a television, a mobile device, or any other type of device capable of displaying visual information. Display surface 200 may be configured to present both monochromatic visual information 202 and injected color information 204.

[0033] Monochromatic visual information 202 may be generated by a monochromatic image generating device (not shown in FIG. 2), which may include reflecting light from a primary light source using a transflective spatial light modulator. Monochromatic visual information 202 may include any type of visual information presented in a single color or in shades of a single color. For example, monochromatic visual information 202 may include text, images, video, or any other type of visual content.

[0034] The injected color information 204 may be generated by a spatially addressable backlight generator (not shown in FIG. 2), which may include an array of color light sources that may be driven to selectively emit light toward the non-reflective side of the transflective spatial light modulator, thereby injecting color light into the monochromatic visual information 202.

[0035] One or more processors (not shown in FIG. 2 ) may be configured to determine injected color information 204 for presentation on display surface 200. One or more processors may also be configured to control color light sources within the spatially addressable backlight generator to emit light toward the non-reflective side of the transflective spatial light modulator, thereby allowing the injected color information 204 to be presented on display surface 200 along with the monochromatic visual information 202.

[0036] In some implementations, display surface 200 may also include other components (not shown in FIG. 2 ). These other components may include, for example, a touch sensor layer, a protective layer, a backlight layer, or any other components typically found in a display device. These other components may be configured to work in conjunction with display surface 200, monochromatic visual information 202, and infused color information 204 to provide a rich and immersive visual experience to the user.

[0037] FIG. 3 illustrates an exemplary implementation of a spatially addressable backlight generator 300, according to some implementations. The term "spatially addressable" refers to the device's ability to independently control different regions. This independent control can enable the generation of backlight that varies in intensity or color across the display. As shown in FIG. 3, the spatially addressable backlight generator 300 can include an array 302 of color light sources 304 and / or other components.

[0038] The spatially addressable backlight generator 300 may be a component of a display device. The spatially addressable backlight generator 300 may be configured to backlight a transflective spatial light modulator, which may be part of a monochrome image generating device. The spatially addressable backlight generator 300 may include an array 302 of color light sources 304 that are driven to selectively emit light toward the non-reflective side of the transflective spatial light modulator. This allows color light to be injected into the monochrome visual information generated by the monochrome image generating device, so that the injected color information is presented on the display surface along with the monochrome visual information.

[0039] The array 302 may be a grid-like arrangement of color light sources 304. The array 302 may be of any size and may be configured to provide localized color to the display. The color light sources 304 in the array 302 may be light emitting diodes (LEDs) capable of emitting light of different colors. The color light sources 304 may be driven to selectively emit light of different colors, thereby providing the ability to address any color.

[0040] The color light sources 304 may be red, green, and blue (RGB) LEDs. The RGB LEDs may be capable of emitting light of different colors when driven by appropriate control signals. The RGB LEDs may be arranged in an array 302 to provide localized color to the display. The RGB LEDs may be driven to selectively emit light of different colors, thereby providing the ability to address any color.

[0041] The spatially addressable backlight generator 300 may be controlled by one or more processors that may be configured to determine injected color information for presentation to a display surface and control color light sources 304 within the spatially addressable backlight generator 300 to emit light toward the non-reflective side of the transflective spatial light modulator, thereby presenting the injected color information to the display surface.

[0042] The spatially addressable backlight generator 300, the array 302, and the color light sources 304 may be components of a display device. The display device may be part of a larger system, such as a computer system, a television system, a mobile device, or any other system that includes a display. The display device may be configured to present visual information, including monochromatic visual information and infused color information, on a display surface.

[0043] 4 is a diagram illustrating an example implementation of a spatially addressable backlight generator 400, according to some implementations. As shown in FIG. 4, the spatially addressable backlight generator 400 may include a color-transmissive liquid crystal display (LCD) stack 402 and / or other components.

[0044] The LCD stack 402 may include multiple layers of liquid crystal material, each capable of transmitting a different color of light. The LCD stack 402 may be controlled by a processor. The processor may determine the color and intensity of light to be transmitted by each layer of the LCD stack 402. The processor also controls the spatially addressable backlight generator 400 to backlight the transflective spatial light modulator, injecting color light into the monochrome visual information produced by the monochrome image generating device.

[0045] The spatially addressable backlight generator 400 may be part of a display device. The display device may include a display surface, a monochrome image generating device, a transflective spatial light modulator, and one or more processors. The display device may be designed to present visual information on the display surface. This visual information includes monochrome visual information generated by the monochrome image generating device and injected color information generated by the spatially addressable backlight generator 400.

[0046] 5 illustrates an exemplary method 500 for using a display device, according to some implementations. For purposes of explanation, the steps of method 500 are described herein as occurring sequentially or linearly. However, multiple steps of method 500 may occur in parallel.

[0047] In step 502, a display device may receive input data. This data may be any form of visual information that needs to be displayed on the device.

[0048] The input data may be processed using one or more processors of the display device in step 504. This processing step may include determining monochromatic visual information and injected color information from the input data.

[0049] In step 506, the display device may control a monochrome image generator to generate monochrome visual information for display on the display surface of the device. This monochrome image generator is responsible for creating grayscale or black and white visual content.

[0050] In step 508, the display device may control a spatially addressable backlight generator to backlight a transflective spatial light modulator of the monochrome image generating device. The spatially addressable backlight generator may include an array of color light sources that are driven to selectively emit light toward the non-reflective side of the transflective spatial light modulator.

[0051] In step 510, the emitted color light is injected into the monochromatic visual information so that the injected color information is presented on the display surface along with the monochromatic visual information.

[0052] In step 512, the injected color information and monochrome visual information may be presented on a display surface, thereby achieving a display that provides some color information while maintaining the high reflectivity of a monochrome display.

[0053] In some implementations, a display system using a color reflective LCD instead of a black and white LCD can be used, which can achieve the same result of producing colors at a different resolution than the display resolution.

[0054] In other implementations, display systems that use different types of light sources instead of LEDs, such as OLEDs or quantum dots, may be used. These technologies also have color-addressable capabilities and can be used to create localized colors.

[0055] Some implementations may be realized in different environments, such as digital signage or advertising displays, where the display system may be used to highlight specific portions of an advertisement or message.

[0056] Some implementations may be applied to other problems, such as improving the readability of text on a display in low light conditions. The system's ability to generate colors at a resolution different from that of the display can be used to highlight important information for easier reading.

[0057] In some implementations, the system may be enabled using different methods, such as using software algorithms, to adjust the color and resolution of the display, which may provide more flexible and customizable options for the user.

[0058] Another technology that may be used in some implementations is e-ink or electronic paper display technology, which may be combined with a grid of LEDs to create a display system that can produce colors at a resolution different from that of the display.

[0059] In some implementations, the system may be applied to the problem of reducing eye strain: by generating colors at a resolution different from the display resolution, the display system may enable a display that is easier on the eyes, thereby reducing eye strain for the user.

[0060] While the present technology has been described in detail for illustrative purposes, based on what are presently considered to be the most practical and preferred implementations, it should be understood that such detail is for that purpose only, and that the present technology is not limited to the disclosed implementations, but on the contrary, is intended to cover modifications and equivalent arrangements within the spirit and scope of the appended claims. For example, it should be understood that the present technology contemplates that, to the extent possible, one or more features of any implementation can be combined with one or more features of any other implementation.
