Description

Technical Field

[0001] This utility model relates to the field of display device technology, and in particular to a display that can show a clock and photo album during idle time without host control. Background Technology

[0002] Currently, monitors are typically in sleep or off state when idle. To display a clock or photo album, the host computer must run a program, which presents the following problems: 1. The display cannot be triggered when the host computer is in sleep mode, requiring an additional wake-up of the host computer, resulting in high power consumption; 2. It relies on host computer software control, leading to poor compatibility and complex settings for different systems; 3. There is no independent low-power display module, and frequent host computer startups when idle shorten the hardware lifespan; 4. The clock / photo album function has low integration with the monitor itself, requiring additional wiring or equipment.

[0003] In the existing technology, the monitor lacks a built-in independent control module for clock / photo album functions, and cannot operate the clock / photo album functions independently of the host. Utility Model Content

[0004] The purpose of this invention is to provide a display that can show a clock and photo album during idle time without the need for host control. The display can independently operate the clock and photo album functions during idle time through a built-in control unit.

[0005] The technical solution adopted in this utility model is: A display for showing a clock and photo album during idle time without host control includes a display, an independent control unit built into the display housing, and a power management unit, a local storage unit, and a clock timing circuit connected to the independent control unit. The independent control unit is electrically connected to an external control host. The independent control unit includes a low-power processor and a display driver circuit. The low-power processor has built-in clock and photo album programs. The local storage unit stores background images for the clock and photo album. The clock timing circuit provides a clock signal. When the independent control unit detects no signal at the external control host interface, the display driver circuit drives the display to show the clock or photo album content under the control of the independent control unit.

[0006] Furthermore, when the independent control unit detects no signal at the external control host interface, the independent control unit controls the power management unit to shut down the unnecessary power supply components of the display, so that the power consumption of the display in idle mode is ≤5W; unnecessary power supply components refer to circuit modules that can be turned off to save power while meeting the display clock and photo album requirements.

[0007] Furthermore, the local storage unit includes built-in flash memory and an SD card interface, capable of storing at least 100 images and supporting offline updates.

[0008] Furthermore, it also includes a solar auxiliary power supply panel; the solar auxiliary power supply panel is disposed on the housing of the display and electrically connected to an independent control unit in order to power the device.

[0009] Furthermore, the independent control unit is connected to a light sensor, which is mounted on the display housing to detect ambient brightness in real time.

[0010] Specifically, the independent control unit has an automatic brightness adjustment function, which adjusts the display brightness of the screen in real time according to the ambient brightness detected by the light sensor, further reducing energy consumption.

[0011] Furthermore, the independent control unit is connected to the control host of the display through a status detection circuit. The status detection detects the corresponding interface signal to generate a trigger signal to the independent control unit.

[0012] Furthermore, the independent control unit has a built-in backup button battery to ensure that the clock continues to run after a power outage.

[0013] Furthermore, the independent control unit is connected to a communication unit that communicates with external devices. The communication unit includes a WiFi chip, an Ethernet interface, or a Bluetooth chip.

[0014] This utility model adopts the above technical solution and has the following advantages compared with the prior art: 1. It is independent of host control, solving the pain point of relying on the host and improving compatibility to 100%; 2. Low power consumption design: the power consumption in idle mode is reduced by 60%, which is more energy-efficient than the traditional solution; 3. Local storage: it supports 16GB-128GB storage without occupying host memory.

[0015] This invention requires no host control and can independently operate the clock and photo album functions during idle time through a built-in control unit. Attached Figure Description

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments; Figure 1 This is a schematic diagram of the structure of a display for an idle clock and photo album that does not require host control according to this utility model. Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0018] like Figure 1As shown, this utility model discloses a display that can show a clock and photo album during idle time without host control. It includes a display, an independent control unit built into the display housing, and a power management unit, a local storage unit, and a clock timing circuit connected to the independent control unit. The independent control unit is electrically connected to an external control host. The independent control unit includes a low-power processor and a display driver circuit. The low-power processor has built-in clock and photo album programs. The local storage unit stores background images for the clock and photo album. The clock timing circuit provides a clock signal. When the independent control unit detects no signal at the external control host interface, the display driver circuit drives the display to show the clock or photo album content under the control of the independent control unit.

[0019] Specifically, the independent control unit uses an ARM Cortex-M4 chip as its core controller, integrating display drivers, storage interfaces, and status detection units. The independent control unit connects to the display motherboard via an internal bus and supports hot-swapping. It also has a built-in backup button battery to ensure the clock continues to run after a power outage.

[0020] Furthermore, as a feasible application example, this utility model has a local content management function, supports automatic decoding and carousel of JPG / PNG images (with a switch interval of 5-60 seconds), and the clock display supports multiple styles such as digital and analog dials; it also has a built-in calendar function that supports customized holiday reminders.

[0021] As a feasible application method, users can switch between clock / photo album modes by short-pressing the physical button on the display, or by receiving instructions from a mobile APP through the communication unit.

[0022] Furthermore, when the independent control unit detects no signal at the external control host interface, the independent control unit controls the power management unit to shut down components that do not require power to the display, so that the power consumption of the display in idle mode is ≤5W.

[0023] Furthermore, the independent control unit uses a 5V / 1A power supply, drawing power from the monitor's internal power supply; the built-in power management unit enables wide voltage input (3.3-12V) to adapt to different monitor power specifications; and in idle mode, it automatically cuts off power to unnecessary circuits.

[0024] Specifically, non-essential power supplies refer to circuits or components that do not affect basic display functions in idle mode but consume additional power, such as audio-related circuits and high-frequency circuits (HDMI / DP interfaces). Non-essential power supplies also refer to auxiliary or high-performance circuit modules that can be turned off to save power while meeting basic display functions (clock / photo album), thereby achieving the design goal of low-power idle display.

[0025] In idle mode, the power management unit can choose to turn off the audio amplifier (such as TPA3110) and the USB hub chip, and only keep the display driver IC (such as SN65DSI86) powered, and the measured power consumption can be reduced to 3.5W.

[0026] Furthermore, as a feasible implementation, the display driver circuit integrates an EDP / LVDS low-power display interface, automatically reducing the screen refresh rate to 30Hz and adjusting the brightness to 10-100cd / m² in idle mode; and adopts dynamic backlight control technology to automatically turn off the backlight in black areas.

[0027] Furthermore, the local storage unit includes built-in flash memory and an SD card interface, capable of storing at least 100 images and supporting offline updates.

[0028] Furthermore, it also includes a solar auxiliary power supply panel; the solar auxiliary power supply panel is configured on the display housing and electrically connected to an independent control unit to power the device. For example, the solar panel can be embedded in the display bezel and connected to the power management unit via a DC-DC converter.

[0029] Furthermore, the independent control unit is connected to a light sensor, which is mounted on the display housing to detect ambient brightness in real time.

[0030] Specifically, the independent control unit has an automatic brightness adjustment function, which adjusts the display brightness of the screen in real time according to the ambient brightness detected by the light sensor, further reducing energy consumption.

[0031] Furthermore, the independent control unit is connected to the control host of the display through a status detection circuit. The status detection detects the corresponding interface signal to generate a trigger signal to the independent control unit.

[0032] Specifically, the status detection circuit is used to detect the host status to trigger the monitor's built-in idle mode. For example, pin 19 of the HDMI interface is the HPD pin. When the host is connected to the monitor and working normally, the host provides a +5V level signal to the monitor through this pin, and this 5V level is monitored through a GPIO pin. When the host enters sleep mode or is disconnected, the 5V signal disappears or goes low. As a feasible application example of this invention, this invention triggers the idle mode when there is no activity for 3 consecutive minutes by monitoring the HDMI / DP interface signal level of the external control host and user input (mouse / keyboard); when the external control host is reactivated, it switches back to normal mode within 0.5 seconds.

[0033] Furthermore, the independent control unit is connected to a communication unit that communicates with external devices. The communication unit includes a WiFi chip, an Ethernet interface, or a Bluetooth chip.

[0034] In summary, the display of this utility model has a built-in independent control unit. During normal operation, it is in standby mode. When the display is idle, the independent control unit takes over the display output by detecting the external control host interface signal and user activity, driving the screen to display the locally stored clock or picture. When the user operates or the host is activated, the display control is immediately released and the normal display state is restored. The whole process does not require the host to participate.

[0035] This utility model adopts the above technical solution and has the following advantages compared with the prior art: 1. It is independent of host control, solving the pain point of relying on the host and improving compatibility to 100%; 2. Low power consumption design: the power consumption in idle mode is reduced by 60%, which is more energy-efficient than the traditional solution; 3. Local storage: it supports 16GB-128GB storage without occupying host memory.

[0036] This invention requires no host control and can independently operate the clock and photo album functions during idle time through a built-in control unit.
