The inventors have found that existing display devices typically employ an image pixel interface (image pixel interface, IPI) in which the entire display data path is single-pixel or multi-pixel uniform. For a single-pixel IPI interface, the problem that a frame and line synchronous display time sequence circuit needs higher clock frequency and is not beneficial to the convergence of a time sequence exists; for the unified IPI interfaces of multiple pixels, the interconnection of different pixel display interfaces is inconvenient because the bit widths of frame and line synchronous display time sequence circuits of the IPI interfaces of different manufacturers are different.

The application can carry out self-adaptive frame and time sequence calculation through hardware, does not need software personnel to carry out manual calculation aiming at different time sequence parameters, reduces the difficulty of software development, and can realize interconnection of different pixel display interfaces.
The present application will be further described by the following description of embodiments with reference to the drawings.
The embodiment provides an adaptive parameter updating method, as shown in fig. 1, including:
301. the method comprises the steps of obtaining a first starting point count value and a first end point count value of each signal state in a plurality of signal states of a time sequence parameter and a time sequence signal of a multi-pixel display interface, wherein the first starting point count value is a starting point count value of an upper line of each signal state, and the first end point count value is an end point count value of the upper line of each signal state.
The adaptive parameter updating method of the present embodiment is applied to a multi-pixel display interface, such as a four-pixel display interface, an eight-pixel display interface, a sixteen-pixel display interface, etc., where the multi-pixel display interface may be an image pixel interface (image pixel interface, IPI). The timing signals are timing signals of frame/line synchronization timing of the multi-pixel display interface, as shown in fig. 2, which is a frame/line synchronization timing diagram of the four-pixel display interface, and as can be seen from fig. 2, the four-pixel display interface includes four timing signals (i.e. a line synchronization signal 0, a line synchronization signal 1, a line synchronization signal 2, and a line synchronization signal 3).
The line timing parameter is a time (line_timing) of each line of the timing signal, wherein each line of the timing signal includes a plurality of signal states, and the line timing parameter is a sum of the times of the plurality of signal states of each line, for example, the plurality of signal states include a line synchronization state (horizontal synchronization, HSYNC), a line back shoulder state (horizontal back porch, HBP), a line active state (horizontal active, HACTIVE), and a line front shoulder state (horizontal front porch, HFP), and then line_timing=hsync+hbp+hactive+hfp.
The first start point count value is a start point count value of the last line of each signal state, the first end point count value is an end point count value of the last line of each signal state, for example, the first start point count value of the HSYNC is 1, and the first end point count value is 5; the HBP has a first endpoint count value of 1 and a first endpoint count value of 8.
302. And determining a second starting point count value of each signal state based on the line sequence parameter, the first starting point count value and the number of pixels supported for transmission by the multi-pixel display interface, wherein the second starting point count value is the starting point count value of each signal state in the current line.
The number of pixels is the number of pixels supported by the multi-pixel display interface, for example, the multi-pixel display interface is a four-pixel display interface, the number of pixels is 4, the multi-pixel display interface is an eight-pixel display interface, the number of pixels is 8, the multi-pixel display interface is a sixteen-pixel display interface, and the number of pixels is 16.
The second starting point count value is the starting point count value of each signal state in the current line, after the time sequence parameter of the time sequence signal and the first starting point count value of each signal state are obtained, the second starting point count value of each signal state is determined based on the time sequence parameter, the first starting point count value and the pixel number of the multi-pixel display interface, the starting point count value of each signal state in the current line is automatically calculated based on the time sequence parameter, the first starting point count value and the pixel number, manual calculation is not needed by software personnel for different time sequence parameters, the software development difficulty is reduced, and because the first starting point count value is determined based on the pixel number supported by the multi-pixel display interface for transmission, interconnection of different pixel display interfaces can be realized.
303. And determining a second end point count value of each signal state based on the line sequence parameter, the first end point count value and the pixel number, wherein the second end point count value is the end point count value of each signal state in the current line.
The second endpoint count value is the endpoint count value of each signal state in the current line, after the time sequence parameter of the time sequence signal and the first endpoint count value of each signal state are obtained, the second endpoint count value of each signal state is determined based on the time sequence parameter, the first endpoint count value and the pixel number, the endpoint count value of each signal state in the current line is automatically calculated based on the time sequence parameter, the first endpoint count value and the pixel number, manual calculation is not needed by software personnel aiming at different time sequence parameters, the software development difficulty is reduced, and because the first endpoint count value is determined based on the pixel number supported by the multi-pixel display interface for transmission, the interconnection of different pixel display interfaces can be realized.
304. The count value for each signal state is updated based on the second start count value and the second end count value.
The embodiment determines the second start count value and the second end count value of each signal state, and updates the start count value and the end count value of each signal state based on the second start count value and the second end count value. For example, if it is determined that the second start point count value of HSYNC is 1 and the second end point count value is 8, the start point count value and the end point count value of HSYNC of the current line are updated to 1 and 8, respectively.
In one implementation, the plurality of signal states includes a row synchronization state (horizontal synchronization, HSYNC), a row back shoulder state (horizontal back porch, HBP), a row active state (horizontal active, HACTIVE), and a row front shoulder state (horizontal front porch, HFP). The starting point count value and the end point count value of the HSYNC, the HBP and the HACTVE are updated when the HACTVE of each line is finished, and the starting point count value and the end point count value of the HFP are updated when the HFP of each line is finished.
In one embodiment, as shown in fig. 3, determining the second starting point count value of each signal state in step 302 based on the time sequence parameter, the first starting point count value and the number of pixels supported by the multi-pixel display interface for transmission may include the following steps 401 to 404, which are specifically as follows:
401. Determining a first corresponding relation based on the time sequence parameter and the number of pixels supported for transmission by the multi-pixel display interface;
402. determining a third starting point count value based on the first starting point count value and the first corresponding relation;
403. when the line sequence parameter can be divided by the number of pixels, determining the third starting point count value as a second starting point count value;
404. when the line sequence parameter is not divisible by the number of pixels, a second starting point count value is determined based on the number of pixels and the third starting point count value.
When determining the second starting point count value of each signal state based on the time sequence parameter, the first starting point count value and the pixel number, the embodiment firstly determines the first corresponding relation based on the time sequence parameter and the pixel number of the multi-pixel display interface, then determines the third starting point count value based on the first starting point count value and the first corresponding relation, then judges whether the time sequence parameter can be divided by the pixel number, and when the time sequence parameter can be divided by the pixel number, determines the third starting point count value as the second starting point count value; conversely, when the line sequence parameter is not divisible by the number of pixels, a second starting point count value is determined based on the number of pixels and the third starting point count value. For example, when the multi-pixel display interface is a four-pixel display interface, the number of pixels n=4, the third start point count value is determined as the second start point count value when the line sequence parameter can be divided by 4, and the second start point count value is determined based on the number of pixels and the third start point count value when the line sequence parameter cannot be divided by 4.
In a specific implementation, the first correspondence is specifically: when the line sequence parameter is divided by the number of pixels, the third start point count value=the first start point count value, and when the line sequence parameter is divided by the remainder of the number of pixels, the third start point count value=the first start point count value+n-M, N represents the number of pixels, and N and M are both positive integers. For example, the number of pixels n=4, and when the line sequence parameter can be divided by 4, the third start point count value=the first start point count value; when the line sequence parameter is divided by more than 4 and 1, the third starting point count value=the first starting point count value+4-1; when the line sequence parameter is divided by more than 4 times 2, the third starting point count value=the first starting point count value+4-2; when the line sequence parameter is divided by more than 4 by 3, the third start point count value=the first start point count value+4-3.
In a specific embodiment, determining the second starting point count value in step 404 based on the number of pixels and the third starting point count value may include the following steps 501-503, which are specifically as follows:
501. comparing the third starting point count value with the pixel number to obtain a first comparison result;
502. when the first comparison result is that the third starting point count value is larger than the pixel number, determining a difference value between the third starting point count value and the pixel number as a second starting point count value;
503. When the first comparison result is that the third start point count value is equal to or smaller than the number of pixels, the third start point count value is determined as the second start point count value.
In a specific implementation manner, when the second starting point count value is determined based on the number of pixels and the third starting point count value, the third starting point count value is compared with the number of pixels to obtain a first comparison result, when the first comparison result is that the third starting point count value is greater than the number of pixels, the difference value between the third starting point count value and the number of pixels is determined to be the second starting point count value, and when the first comparison result is that the third starting point count value is equal to or less than the number of pixels, the third starting point count value is determined to be the second starting point count value. For example, the number of pixels n=4, and when the third start point count value is greater than 4, the second start point count value=third start point count value-4; conversely, when the third start point count value is equal to or smaller than 4, the second start point count value=the third start point count value.
In a specific embodiment, with continued reference to fig. 3, determining the second endpoint count value for each signal state in step 303 based on the time sequence parameter, the first endpoint count value, and the number of pixels may include the following steps 405-409, which are specifically as follows:
405. Determining a second corresponding relation based on the time sequence parameter and the pixel number;
406. determining a third endpoint count value based on the first endpoint count value and the second correspondence;
407. determining the third endpoint count value as the second endpoint count value when the time sequence parameter is divisible by the number of pixels;
408. determining a timing value for each signal state when the timing parameter is not divisible by the number of pixels;
409. a second endpoint count value is determined based on the timing value, the number of pixels, and the third endpoint count value.
When determining the second endpoint count value of each signal state based on the line time parameter, the first endpoint count value and the pixel number, the embodiment firstly determines the second correspondence based on the line time parameter and the pixel number of the multi-pixel display interface, then determines the third endpoint count value based on the first endpoint count value and the second correspondence, then determines whether the line time parameter can be divided by the pixel number, and determines the third endpoint count value as the second endpoint count value when the line time parameter can be divided by the pixel number; otherwise, when the time sequence parameter is not divided by the number of pixels, determining a time sequence value of each signal state, and determining a second end point count value based on the time sequence value, the number of pixels and the third end point count value.

In a specific implementation manner, the second correspondence relationship is specifically: when the line sequence parameter is divided by the number of pixels, the third endpoint count value=the first endpoint count value, and when the line sequence parameter is divided by the remainder of the number of pixels, the third endpoint count value=the first endpoint count value+n-M, N represents the number of pixels, and N and M are both positive integers. For example, when the multi-pixel display interface is a four-pixel display interface, the number of pixels n=4, and when the line sequence parameter can be divided by 4, the third endpoint count value=the first endpoint count value; when the time sequence parameter is divided by more than 4 and 1, the third endpoint count value=the first endpoint count value +4-1; when the time sequence parameter is divided by more than 4 times 2, the third endpoint count value=the first endpoint count value +4-2; when the line sequence parameter is divided by more than 4 by 3, the third endpoint count value=the first endpoint count value +4-3.

For example, the number of pixels n=4, and when the first count value is greater than 4, the timing value=first count value-number of pixels; when the first count value is equal to or smaller than 4, the timing value=the first count value.
In one embodiment, when determining the first count value based on the timing parameter and the first endpoint count value, a remainder of the timing parameter divided by the number of pixels is first determined, and then a second count value is determined based on the first endpoint count value, the remainder, and the number of pixels. Wherein, the calculation formula of the second count value is: second count value=first end point count value+n-M, N represents the number of pixels, M represents the remainder of dividing the line sequence parameter by the number of pixels, and N and M are both positive integers.
