All other embodiments, based on the embodiments of the utility model, which are apparent to those of ordinary skill in the art without inventive faculty, are intended to be within the scope of the utility model. Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, based on the embodiments of the utility model, which are apparent to those of ordinary skill in the art without inventive faculty, are intended to be within the scope of the utility model.

Specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

The utility model discloses a device for realizing double MIPI and electronic equipment, and aims to solve the problem that an existing CPU cannot adjust the refresh rate of a screen based on the requirement of the CPU.

Referring to fig. 1, a first embodiment of the present invention provides an apparatus for implementing dual MIPI, including: the PCB, the CPU1, the conversion IC2 and the anti-electromagnetic loop 3 which are arranged on the PCB;

The DSI single MIPI bus of the CPU1 is electrically connected with the DSI receiver of the conversion IC2, the first DSI driver and the second DSI driver of the conversion IC2 are electrically connected with the input end of the anti-electromagnetic loop 3, and the output end of the anti-electromagnetic loop 3 is used for being connected with the display screen assembly 4;

Wherein the CPU1 is configured to identify the identity of the conversion IC2 to initialize the conversion IC2 so that the conversion IC2 can convert a single MIPI into a double MIPI.

The inventors found that: the client can now freely adjust the refresh rate of the screen according to his own preferences and scene requirements to obtain a better user experience. However, to achieve high resolution and high refresh rate screens, the dual MIPI (Mobile Industry Processor Interface) technology is required to provide adequate data transfer bandwidth. However, many mobile CPUs 1 in the world do not directly support dual MIPI output, so it is necessary to convert single channel MIPI signals into dual channels by using a single MIPI to dual MIPI conversion IC2 to adapt to the requirements of high performance screens, thereby achieving a higher quality visual experience. In this embodiment, the chip type of the conversion IC2 may be IT6112 or GM8733, but of course, may be other types, which is not limited herein, the CPU1 connects the DSI single mipi bus to the conversion IC2 IT6112/GM8733, and outputs data to the conversion IC2 through the single mipi bus, the conversion IC2 receives the data of the single mipi and then performs data processing, thereby converting the data to a display screen with a dual mipi interface, and after receiving the data, the screen converts the data to corresponding RGB to display on the screen, thereby becoming a signal that can be recognized by human eyes, and the inventor further finds that: the hardware designs IT6112 and GM8773 are completely identical in pin-to-pin and peripheral materials, so that the hardware is alternatively attached to the main board. However, the registers of the two chips are different in configuration, so that the two ICs are required to be compatible in a distinguishing manner, by reading the identifier (vendor ID) of the conversion IC2, and initializing the conversion IC2 through the I2C interface based on the identifier. The CPU1 further provides the single-way MIPI signal to the conversion IC2, and the conversion IC2 converts the single-way MIPI signal into a dual MIPI signal (for example IT6112, as shown in fig. 2 and 3 in particular), so that the display screen assembly 4 can meet the refresh rate requirement of the user.

In this embodiment, as shown in fig. 4, the anti-electromagnetic loop 3 is designed to have a specific circuit structure, so that the anti-electromagnetic loop 3 can reduce or inhibit the propagation of electromagnetic interference signals within a certain frequency range, and ensure the normal operation of the device. Further, it can prevent external electromagnetic radiation or interference from affecting the internal circuitry of the device, and for some specific environments, such as industrial control devices or medical devices, the anti-electromagnetic loop 3 can improve the resistance of the device to electromagnetic interference, thereby protecting the normal operation of the device. Of course, in some cases, anti-electromagnetic loop 3 may help optimize signal transmission, reducing data transmission errors due to electromagnetic interference.

The second embodiment of the present invention provides an electronic device, including: a power supply, a power supply loop, a display screen assembly 4 and a device for realizing double MIPI according to any one of the above;

The power supply is configured to supply power to the CPU1, the conversion IC2 and the display screen assembly 4 through the power supply loop, and an input end of the display screen assembly 4 is electrically connected with an output end of the electromagnetic loop.

In this embodiment, the display screen assembly 4 includes a display screen connecting seat and a display screen;

It should be noted that the display screen assembly 4 further includes a positive and negative bias circuit (as shown in fig. 5) disposed between the power supply terminal and the power supply output terminal of the display screen, where the positive and negative bias circuits can ensure that the amplifier or other signal processing device operates in a suitable operating area to maintain a stable operating state during operation. In many amplification circuits, the signal is typically an alternating voltage, and the positive and negative bias circuits may "step up" or "step down" the waveform of the signal to within a suitable operating range to facilitate the amplification of the signal by the amplifier. By providing an appropriate bias, it is ensured that the amplifier operates in a linear region, thereby enabling the amplifier to accurately amplify the input signal. In some cases, if the input signal to the amplifier is not properly biased, it may result in clipping or distortion of the signal waveform, which may be avoided by the positive and negative bias circuits. Meanwhile, different signal sources may have different signal bias requirements, and the positive and negative bias circuits can provide corresponding bias voltages according to specific signal source characteristics.

Referring to fig. 6, the display screen connector provides a physical interface to connect the display screen and the PCB board. This ensures that the display screen can normally receive signals from the main board and display images. Through the display screen connecting seat, the PCB board can transmit necessary information such as video signals, power signals and the like to the display screen. This enables the display screen to correctly display images from the device. The display screen connecting seat is compact, so that the space inside the equipment can be saved, and the design of the equipment is more compact and efficient.

Based on the device and the electronic device for realizing double MIPI, when the electronic device needs to convert single MIPI into double MIPI output, the CPU1 can identify the identification of the conversion IC2, namely confirm the model of the conversion IC2, initialize the conversion IC based on the model pair of the conversion IC2, and further the CPU1 provides a single MIPI signal for the conversion IC2, and the conversion IC2 converts the single MIPI signal into the double MIPI signal, so that the display screen component 4 can meet the refresh rate requirement of a user.

The above is only a preferred embodiment of the present utility model, and the protection scope of the present utility model is not limited to the above examples, and all technical solutions belonging to the concept of the present utility model belong to the protection scope of the present utility model.
