All other embodiments that can be derived by one of ordinary skill in the art from the description herein are intended to be within the scope of the present disclosure.
In order to realize remote control of a display, an embodiment of the present application provides a display, see fig. 1, including:
the infrared detector comprises an infrared detector panel 11 and a processing module 12, wherein the infrared detector panel 11 comprises a plurality of unit detection areas 111, and for any unit detection area 111, when infrared rays irradiate on the unit detection area 111, electric charges of the unit detection area 111 are accumulated;
the processing module 12 is configured to obtain charge information of each unit detection area 111 in the infrared detector screen; determining a target unit detection area irradiated by infrared rays according to the charge information of each unit detection area 111; determining a target pixel corresponding to the target unit detection area; triggering an operation for the target pixel.
The infrared detector screen has functions of infrared detection and image display, in one example, a transparent infrared detector layer can be added on the basis of a conventional display screen, and in one example, the functions of the infrared detector can be integrated into a pixel circuit, which are all within the protection scope of the present application.
The infrared detector panel 11 includes a plurality of unit detection areas 111, and in one example, as shown in fig. 2, the unit detection areas 111 may be arranged in a rectangular shape and are distributed over the display area of the infrared detector panel 11.
The user irradiates a desired operation position on the display with infrared light, such as an infrared laser pen, etc., and on an infrared detector screen of the display, a unit detection area receiving the infrared light generates charge accumulation, while a unit detection area not irradiated with the infrared light has no charge accumulation. The processing module can determine the unit detection area irradiated by the infrared ray according to the charge information of each unit detection area, and the unit detection area irradiated by the infrared ray is called as a target unit detection area. The unit detection area and the pixel have a corresponding relationship on the position, so that the pixel corresponding to (covered by) the target unit detection area can be determined, and the pixel corresponding to the target unit detection area is called a target pixel; triggering an operation for the target pixel.
In the embodiment of the application, the charge information of each unit detection area in the infrared detector screen is detected, the target unit detection area irradiated by infrared rays is determined, the target pixel corresponding to the target unit detection area is determined, and the operation aiming at the target pixel is triggered, so that the display is remotely controlled by using the infrared rays.
The processing module needs to include a processor or the like, which in one possible embodiment, see fig. 3, includes a PCB (Printed Circuit Board) 121 and a processor 122;
the printed circuit board 121 is configured to collect charge information of each unit detection region, and convert the charge information of each unit detection region into screen gray scale information, where in the screen gray scale information, gray scale information at a unit detection region with infrared radiation is different from gray scale information at a unit detection region without infrared radiation;
the processor 122 is configured to determine a target unit detection area irradiated by infrared rays according to the screen gray scale information; determining a target pixel corresponding to the target unit detection area; triggering an operation for the target pixel.
In order to facilitate the processing of the processor, it is necessary to convert the charge information into digital signals, i.e. the charge information of each unit detection area is converted into screen gray scale information, and the areas irradiated by infrared rays and the areas not irradiated by infrared rays can be distinguished by different gray scale values. The processor may analyze the screen gray scale information to determine a target unit detection region, determine a target pixel corresponding to the target unit detection region, and trigger an operation for the target pixel.
The printed circuit board can realize conversion from a model signal to a digital signal, and in one possible embodiment, the printed circuit board includes an FPGA (Field-Programmable Gate Array) and a plurality of ROICs (data readout chips), wherein each ROIC corresponds to a plurality of unit detection areas;
the ROIC is used for acquiring charge information of a unit detection area corresponding to the ROIC and converting the charge information of the unit detection area corresponding to the ROIC into area gray scale information;
and the FPGA is used for processing the regional gray information of each ROIC to obtain the screen gray information.
Each ROIC may correspond to a plurality of unit detection regions and collect charge information of each unit detection region corresponding to itself. The number of unit detection areas actually corresponding to each ROIC may be set according to the ROIC actual acquisition function, and in one example, each ROIC may correspond to 256 columns of unit detection areas.
The length of data (area gray scale information) output by the ROIC is 16 bits, and the unit detection area only has two conditions of being irradiated by infrared rays and not being irradiated by the infrared rays, so that whether the unit detection area is irradiated by the infrared rays can be determined by judging the numerical value of a specific digit in the 16-bit data in one example; optionally, this data is a neutral position, which may be 16bit, to filter the effect of ambient light on the infrared detector.
For a unit detection region, if not irradiated by infrared rays, the data of the unit detection region 16bit output by the ROIC should theoretically be 0000-; if the light is irradiated, there is gray scale information, and the output results are not all 0, such as 0000-0110-1100-0101. However, due to the interference of factors such as ambient light, a slight amount of charge accumulation may occur in the unit detection region that is not irradiated with infrared light, and in order to eliminate the interference, it is determined that the data is irradiated with infrared light when the 16 bits of the data are not all 0 and are greater than 0000-. In one example, a value of 0 for the selected digit indicates that the corresponding unit sensing region is not irradiated with the laser beam, and a value of 1 for the selected digit indicates that the corresponding unit sensing region is irradiated with the laser beam.
If the charge information of the unit detection area is always collected by the ROIC, the data collected by the ROIC is large in quantity, and many data are repeated, so that the data can be subjected to pooling operation. In one possible implementation, the ROIC is specifically configured to: and acquiring the charge information of the unit detection area corresponding to the unit detection area according to a preset sampling interval.
The preset sampling interval can be customized according to practical situations, for example, the charge information is collected once every 5 frames, 10 frames or 20 frames of video frames, or the charge information is collected once every 50 milliseconds, 100 milliseconds or 200 milliseconds, and the like. The charge information of the unit detection area is collected according to the preset sampling interval, so that the data volume of repeated data can be reduced, and the data processing efficiency is improved.
In one example, as shown in fig. 4, the printed circuit board further includes a power module, a Gate IC (Gate driver circuit), a USB (Universal Serial Bus) port, a Mini USB port, an Ethernet port, an SD Card (Secure Digital Memory Card), and the like. The printed circuit board may interact with the processor via a USB port or the like.
The Gate ICs are used to provide Gate driving voltages for the unit sensing regions, and the number of unit sensing regions corresponding to the Gate ICs may be determined according to actual driving capability of the Gate ICs, and in one example, each Gate IC may provide Gate driving voltages for 512 rows of unit sensing regions.
The digital circuit works in a switching state, the interference on the power supply voltage is serious, and the digital circuit and the analog circuit can be independently powered to avoid the influence of ripple interference on the analog circuit through a power supply path; in a possible implementation, the printed circuit board further includes a digital circuit power supply module and an analog circuit power supply module;

The digital circuit part is powered by a DC-DC power supply, the analog circuit part is powered by the combination of the DC-DC and an LDO (Low Dropout Regulator), decoupling capacitance, a ground plane, electromagnetic interference and other factors are considered, and finally, the loops of the digital circuit part and the analog circuit part are connected through magnetic beads to realize common ground processing.
In a possible implementation manner, the ROIC is connected to the FPGA through a differential line, and the ROIC is further configured to send the area grayscale information obtained by the ROIC to the FPGA through the differential line in a differential transmission manner.
Differential transmission is a signal transmission technology, and is different from a transmission mode of one signal wire and one ground wire in the prior art, the differential transmission transmits signals on the two wires, the amplitudes of the two signals are equal, the phase difference is 180 degrees, and the polarities are opposite. In one example, the differential transmission mode may be implemented by coupling transmitted data, two lines in the differential line are not wired separately and are close to each other as much as possible, meanwhile, the punching and layer changing processing is not performed, the differential line is wired with high-speed signals, and the two lines are processed with equal length and equal width. A differential line is used between the ROIC and the FPGA, data interaction is realized by adopting a differential transmission mode, and the transmission speed of data can be increased.
In the prior art, a clock signal from an FPGA to an ROIC is composed of a single clock signal line path, different bank cmcc (pins for outputting clock signals in the FPGA) is used in the FPGA to generate clock signals which are respectively distributed to the ROICs, the clock signals are generated by different banks and the clock signal line paths are different, so that the ROIC clock signals are asynchronous, and data acquired and output among a plurality of ROICs are asynchronous (data acquired and output in the same cycle of the plurality of ROICs are not the same time), thereby affecting the accuracy of control of a display.
In order to reduce the clock error of each ROIC, in one possible embodiment, the printed circuit board further includes a clock distribution chip, and the clock distribution chip is connected to each ROIC through clock signal lines with equal length;

The specific mode of triggering the operation for the target pixel can be an operation mode of touching the pixel by a finger in the touch screen, or a corresponding operation mode can be set by self-definition.
