Detailed Description
For the purposes of making the objects, technical solutions and advantages of the present application more apparent, the technical solutions in the present application will be clearly and completely described below with reference to the drawings in the present application, and it is apparent that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
In embodiments of the present application, "at least one" means one or more, and "a plurality" means two or more. "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: there are three cases, a alone, a and B together, and B alone, wherein a, B may be singular or plural. In the text description of the present application, the character "/" generally indicates that the front-rear association object is an or relationship.
The technical scheme provided by the embodiment of the application can be applied to a chip driving scene, and the chip driving scene with the Wifi function is taken as an example, and in the subsequent description, the chip with the Wifi function can be simply called as a Wifi chip. Along with the development of product intelligence, chips in the product are required to have a Wifi function. If the Wifi chip can also drive the TFT screen, the market competitiveness of the product can be effectively improved.
The existing TFT screen is generally provided with two interfaces, one is SPI and the other is RGB; correspondingly, the Wifi chip for driving the TFT screen is also provided with two interfaces, one is SPI, and the other is RGB interface, so that the TFT screen is driven to display through the SPI and the RGB interface.
However, since a single SPI has only 1 data line, the refresh frequency of the TFT screen is low, and the RGB interface has 24 data lines, which occupies a large amount of GPIOs.
In order to achieve the purpose of improving the refresh frequency of the TFT screen under the condition of occupying less GPIOs, in the embodiment of the present application, the number of data lines in the Wifi chip interface can be considered to be reduced to a certain extent, and at present, a Wifi chip with related functions is provided with two-way queue serial peripheral interfaces (Queue Serial peripheral interface, QSPI), but functions corresponding to the two-way QSPI are not limited.
In the embodiment of the application, in order to improve the refresh frequency of the TFT screen under the condition of occupying less GPIOs, functions corresponding to two paths of QSPI can be limited, wherein one path of QSPI is connected with the customized TEF screen, and the other path of QSPI is connected with the external storage space FLASH of the Wifi chip. For example, referring to fig. 1, fig. 1 is a schematic structural diagram of a Wifi chip provided in an embodiment of the present application, based on the Wifi chip structure shown in fig. 1, the embodiment of the present application provides a TFT screen driving system, including the Wifi chip and the TFT screen shown in fig. 1, where the chip and the TFT screen are connected through a first queue serial peripheral interface, and the first queue serial peripheral interface is a QSPI connected with a customized TFT screen. The chip is used for acquiring target data to be displayed and sending a driving instruction to the TFT screen through the first queue serial peripheral interface; the driving instruction comprises target data; and a TFT screen for displaying the target data based on the driving instruction.
Wherein the customized TEF screen supports QSPI. For example, the resolution of the customized TEF screen may be 480X360, the refresh frequency may be 55 frames, and the specific setting may be set according to the actual needs, which is not limited in this embodiment.
In view of the fact that QSPI only has 4 data lines, occupation of GPIO can be effectively reduced compared with 24 data lines of an RGB interface; compared with 1 data line of a single SPI, the number of data lines is increased, so that in the embodiment of the application, a drive command is sent to the TFT screen through QSPI with 4 data lines, and the refresh frequency of the TFT screen is improved under the condition of occupying less GPIO.
It should be noted that, the chip in the TFT screen driving system provided in the embodiment of the present application is not limited to a Wifi chip, but may be other similar chips, and may be specifically set according to actual needs.
In addition, in this embodiment of the present application, the Wifi chip may further include some peripheral circuits common to Wifi chips, for example, as shown in fig. 1, an indicator light circuit, a buzzer and driving circuit, an infrared remote control receiving circuit, a power supply and carrier communication circuit, a temperature sensor, a humidity sensor, a touch circuit, and the like, which may be specifically set according to actual needs.
Hereinafter, a thin film transistor TFT panel driving system provided in the present application will be described in detail by means of the following several specific examples. It is to be understood that the following embodiments may be combined with each other and that some embodiments may not be repeated for the same or similar concepts or processes.
Fig. 2 is a schematic structural diagram of a TFT panel driving system for a thin film transistor according to an embodiment of the present application, and for example, referring to fig. 2, the TFT panel driving system for a thin film transistor may include a chip and a TFT panel, where the chip and the TFT panel are connected through a first queue serial peripheral interface.
The chip is used for acquiring target data to be displayed and sending a driving instruction to the TFT screen through the first queue serial peripheral interface; the driving instruction comprises target data;
and a TFT screen for displaying the target data based on the driving instruction.
For example, the target data may be image data, text data, or the like, and may be specifically set according to actual needs, where the data type of the target data is not specifically limited in the embodiments of the present application.
After the chip obtains the target data to be displayed, a driving instruction can be sent to the TFT screen through the first queue serial peripheral interface, so that the TFT screen displays the target data based on the driving instruction. The first queue serial peripheral interface is QSPI between the chip and the customized TFT screen.
Illustratively, when driving the FTF panel to display target data, the TFT panel full output may be: 480x360 x 24 bits = 4147200 bits, corresponding to 4M. In this case, if the existing SPI including only 1 data line is used and the refresh frequency of the TFT screen is expected to reach 55 frames, the Clock (CLK) of the SPI needs to reach 200MHz, and typically CLK is at least half of the main frequency of the central processing unit (Central Processing Unit, CPU), which means that the Clock frequency of the CPU needs to reach 400MHz, and the requirement for the CPU is extremely high. In the embodiment of the application, the QSPI including 4 data lines is adopted, if the refresh frequency of the TFT screen is expected to reach 55 frames, the CLK of the QSPI only needs 50Mhz, which means that the clock frequency of the CPU needs to reach 100Mhz, so that the requirement on the CPU can be effectively reduced, and the risk of electromagnetic compatibility (Electro Magnetic Compatibility, EMC) can be effectively reduced.
It can be seen that, in the embodiment of the present application, when the TFT screen is driven, the chip acquires target data to be displayed; transmitting a driving instruction to the TFT screen through a first queue serial peripheral interface; the driving instruction comprises target data, and the TFT screen displays the target data based on the driving instruction. In view of the fact that the first queue serial peripheral interface only has 4 data lines, a driving instruction is sent to the TFT screen through the first queue serial peripheral interface, so that fewer GPIOs are occupied, the refreshing frequency of the TFT screen is improved, and the refreshing frequency of the TFT screen is improved under the condition that fewer GPIOs are occupied.
Based on the embodiment shown in fig. 2 described above, the chip may include a direct memory access (Direct Memory Access, DMA) controller and a central processor, for example, in embodiments of the present application.
The central processing unit is used for sending a control instruction to the direct memory access controller, wherein the control instruction is used for indicating the direct memory access controller to acquire target data;
and the direct memory access controller is used for acquiring target data based on the control instruction and sending a driving instruction to the TFT screen through the first queue serial peripheral interface.
After detecting a display instruction triggered by a user, a CPU in the chip controls the direct memory access controller to acquire target data, and sends a driving instruction to the TFT screen through the first queue serial peripheral interface, so that the CPU resource can be released while the normal display of the target data is ensured, and other operations such as WiFi functions, temperature control algorithms and the like can be executed by the CPU resource.
Based on any of the above embodiments, for example, in the embodiment of the present application, when the direct memory access controller in the chip acquires target data to be displayed, the chip further includes an internal storage space in order to improve the efficiency of acquiring the target data.
And the direct memory access controller is used for searching and acquiring target data from the internal storage space based on the control instruction.
If the target data is not found in the internal storage space, the TFT screen driving system for a thin film transistor in the embodiment of the present application further includes an external storage space.
And the direct memory access controller is further used for acquiring the target data from the external storage space through the second queue serial peripheral interface based on the result that the target data is not searched from the internal storage space.
The second queue serial peripheral interface is the QSPI between the chip and the external storage space.
For example, in the embodiment of the present application, the internal Memory space of the chip may be a Static Random-Access Memory (SRAM), a dynamic Random-Access Memory (Dynamic Random Access Memory, DRAM), a synchronous dynamic Random-Access Memory (synchronous dynamic Random-Access Memory, SDRAM), or a pseudo-Static Random-Access Memory (Pseudo Static Random Access Memory, PSRAM), which may be specifically set according to actual needs. When the internal memory space of the chip is selected, the memory space may be selected to be at least 2 times of the entire TFT, and in this embodiment, the internal memory space of the chip may be PSRAM, for example.
For example, in the embodiment of the present application, the external storage space may be FLASH with relatively large plug-in capacity, which is generally more than 8M. Considering that TFT screen writing application software needs to store data such as pictures, word libraries, algorithms, etc., for example, in the embodiment of the present application, the external storage space may be a 16M storage space.
In this embodiment of the present application, the direct memory access controller may be one way or two ways, and may specifically be set according to actual needs.
It can be understood that, in the case that the direct memory access controller is one way, the direct memory access controller needs to perform the operation of acquiring the target data from the internal storage space of the chip, and also needs to perform the operation of acquiring the target data from the external storage space of the chip in the case that the target data is not found in the internal storage space. Under the condition that the direct memory access controllers are two paths, one path of direct memory access controller executes the operation of acquiring target data from the internal storage space of the chip; and the other path of direct memory access controller executes the operation of acquiring the target data from the external storage space of the chip under the condition that the target data is not found in the internal storage space. In the embodiment of the application, two paths of direct memory access controllers can be adopted.
It should be noted that, the other direct memory access controller may acquire data from other functions besides performing the operation of acquiring the target data from the external memory space of the chip, and may specifically be set according to actual needs.
Based on any of the above embodiments, illustratively, in an embodiment of the present application, the chip further includes a cache space.
And the direct memory access controller is used for caching the target data into the cache space, determining that the preset period arrives, and sending a driving instruction to the TFT screen through the serial peripheral interface of the first queue so as to drive the TFT screen to display the target data through the driving instruction.
The value of the preset period can be set according to actual needs, in general, a continuous space needs to be guaranteed in the memory pool to serve as a buffer of the TFT, and the program waits for timing of screen refreshing, for example, 50 frames, namely, 20ms full screen refreshing is performed once, and the preset period can be set to be 20ms. When the timer counts 20ms, the direct memory access controller sends a driving instruction to the TFT panel through the first queue serial peripheral interface so as to drive the TFT panel to display target data through the driving instruction.
In the embodiment of the present application, if a terminal interrupt, for example, a terminal screen is turned off, a screen is turned on, or turned off, is detected in the timing process, the timing may be stopped, and the TFT screen driving method provided in the embodiment of the present application may be stopped.

A direct memory access controller for sending a driving instruction to a controller of the first queue serial peripheral interface;
and the controller is used for controlling the first queue serial peripheral interface to send a driving instruction to the TFT screen.
