Detailed Description

The embodiments of the present application will be described below with reference to the drawings.

The term "and/or" in this application is only one kind of association relationship describing the associated object, and means that there may be three kinds of relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" in this document indicates that the former and latter related objects are in an "or" relationship.

The "plurality" appearing in the embodiments of the present application means two or more. The descriptions of the first, second, etc. appearing in the embodiments of the present application are only for illustrating and differentiating the objects, and do not represent the order or the particular limitation of the number of the devices in the embodiments of the present application, and do not constitute any limitation to the embodiments of the present application. The term "connect" in the embodiments of the present application refers to various connection manners, such as direct connection or indirect connection, to implement communication between devices, which is not limited in this embodiment of the present application.

MIPI (mobile industry Processor Interface) is an open standard developed for mobile application processors, initiated by the MIPI alliance, including the companies ARM, samsung, intel, etc. The bridge chip converts the input signal into an MIPI timing sequence interface signal through an internal conversion mechanism in an image VIDEO mode or a COMMAND COMMAND mode.

The TE signal is a signal generated by a chip to prevent a tearing problem in a picture refresh in an image display process. When the next frame of image is ready to be refreshed, the chip generates the TE signal, and optionally, the AP sends the next frame of image data to the chip after monitoring the rising edge of the TE signal or detecting that the TE signal is in a high level state.

VSYNC is a vertical synchronizing signal which is a frame synchronizing signal of an image mode and is triggered between one frame picture and another frame picture; the reason for the tearing of the frame is that if there is no vertical synchronization signal, when the frame data rendered by the engine is faster, the display screen cannot keep up (if a frame is rendered for 10ms, and the display refresh period of the display screen is 16ms, the display screen is within the display duration range of 16ms, and the GPU has rendered 1.6 frames of image data, which results in the tearing phenomenon caused by the previous frame of image being covered by the next frame of image data), it may happen that a certain frame is currently displayed, and another frame is triggered to be displayed on the display screen.

Referring to fig. 1, fig. 1 provides a block diagram of an application of a chip, as shown in fig. 1, which includes an AP connected to a chip (e.g., LCDC) and a chip connected to an LCD.

In the Video mode, the VIDC module notifies the LCDC module to perform data synchronous transmission through a frame start signal, and the LCDC module completes data processing and notifies the MIPI TX module to perform data synchronous transmission through an output-end frame synchronization Vsync _ out signal.

Referring to fig. 3, fig. 3 provides a resolution real-time switching control method, which is executed under the structure of the chip display data path shown in fig. 2, and the method shown in fig. 3 includes the following steps:

step S301, receiving a resolution switching instruction, stopping hardware TE, and reconfiguring RXBR, DSC and VIDC modules; starting an RX module to Start to wait for the AP to send display data, and receiving the display data sent by the AP (namely receiving an RXBR Frame Start signal);

step S302, judging whether the LCDC _ LINE _ STS is larger than gen _ TE _ LINE or not, if the LCDC _ LINE _ STS is larger than gen _ TE _ LINE, generating software TE according to the LCDC _ LINE _ STS, continuously judging the value of the LCDC _ LINE _ STS, if the value of the LCDC _ LINE _ STS is larger than or equal to VBP + VACT, making TX Power Down, not outputting next Frame data, and waiting for an RXBR Frame End signal;

step S303, after receiving the RXBR Frame End signal, after the configuration of TX, LCDC and MEMC reset for the initial resolution is restarted, the display is restarted, and the software TE is switched into a hardware TE mode.

The technical scheme provided by the application receives a resolution switching instruction, stops the hardware TE, and reconfigures the RXBR, DSC and VIDC modules; starting an RX module to Start to wait for the AP to send display data, and receiving the display data sent by the AP (namely receiving an RXBR Frame Start signal); judging whether the LCDC _ LINE _ STS is larger than gen _ TE _ LINE or not, if the LCDC _ LINE _ STS is larger than gen _ TE _ LINE, generating software TE according to the LCDC _ LINE _ STS, continuously judging the value of the LCDC _ LINE _ STS, and if the value of the LCDC _ LINE _ STS is larger than or equal to VBP + VACT, making TXPower Down, not outputting the next Frame data, and waiting for an RXBR Frame End signal; after receiving the RXBR Frame End signal, after the configuration of the original resolution ratio is restarted by the TX, the LCDC and the MEMC reset, the display is restarted, and the software TE is switched to the hardware TE mode. Through the technical scheme, when the software TE is generated, the LCDC _ LINE _ STS is required to be larger than the gen _ TE _ LINE, so that a splash screen can be avoided, and the experience of switching resolution of a user display screen is improved.

For example, the method may further include:

if the LCDC _ LINE _ STS is smaller than gen _ TE _ LINE, it is determined whether the LCDC _ LINE _ STS is larger than gen _ TE _ LINE after a set time (e.g., 15 ms or 10ms, etc.) is delayed, and if the LCDC _ LINE _ STS is larger than gen _ TE _ LINE, the software TE is generated according to the LCDC _ LINE _ STS.

For example, the method may further include, before steps S302 and S303:

if the TXPower Down action is not performed after the RXBR Frame End signal is received, adjusting the gen _ TE _ line position and performing the TX Power Down action, restarting display after the configuration of the initial resolution ratio of the TX, the LCDC and the MEMC reset is restarted, and switching the software TE into a hardware TE mode.

For the AP, if the TX Power Down action is not performed after the RXBR FrameEnd signal is received, it indicates that the AP write time catches up with the reading of the LCDC, which may cause the splash screen phenomenon, and therefore, the gen _ te _ line position needs to be adjusted, so that the AP write time is after the reading time of the LCDC, and the splash screen is avoided.

For example, the adjusting the gen _ te _ line position may specifically include:

advancing the gen _ te _ line position forward by a set time;

or the gen _ te _ LINE position is adjusted forward step by step until the LCDC _ LINE _ STS is larger than the gen _ te _ LINE.

As an example of this, it is possible to provide,

the judging and processing unit is further configured to restart the display after the TX, the LCDC and the MEMC reset are configured for the initial resolution again after the TX, LCDC and MEMC reset are configured, and the software TE is switched to the hardware TE mode if the receiving unit does not perform the TX Power Down action after receiving the RXBR Frame End signal, adjusts the gen _ TE _ line position and performs the TX Power Down action.
