In the description of the present application, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.
Referring to fig. 1, a liquid crystal driving board 110 according to an embodiment of the present application will be described.
In an embodiment of the present application, the liquid crystal driving panel 110 may include a first input interface 111, a signal distributor 112, a processor 113, a first output interface 114, and a second output interface 115. The liquid crystal driving panel 110 is a component for driving and displaying the liquid crystal display panel 120.
The first input interface 111 may be configured to receive a first multimedia signal. The first multimedia signal may be a video signal, an audio signal, or other multimedia signal.
The signal distributor 112 is connected to the first input interface 111 and is configured to copy the first multimedia signal into a plurality of first multimedia signals. In particular, the signal distributor 112 may be configured to replicate the first multimedia signal into multiple paths, thereby enabling multiplexing of the signals, wherein each path of the media signal may be provided as an input source to a different device.
The processor 113 is connected to the signal distributor 112, and is configured to process the first multimedia signal, and output the processed signal to the liquid crystal display panel 120 for display through the first output interface 114. In particular, the processor 113 may include one or more chips, particularly FPGA (Field Programmable Gate Array), ARM (Advanced RISC Machines) chips or other special purpose chips, which may be high computing power. The processor 113 may perform processes such as parsing and correcting on the first multimedia signal, and control the first output interface 114 to output the processed signal to the liquid crystal display panel 120 for display.
The second output interface 115, which is connected to the signal distributor 112, may be used to output the first multimedia signal to the cascade device 130, which is cascade-connected to the liquid crystal driving panel 110. The cascade device 130 may be another liquid crystal driving board 110, or may be an HDMI input device, an HDMI splitter, or the like.
For example, the first input interface 111 may be a HDMI (High Definition Multimedia Interface) interface, the signal splitter 112 may be an HDMI one-to-two chip, and the second output interface 115 may be an HDMI interface. The HDMI one-to-two chip can divide an HDMI signal input from an HDMI interface into two to obtain two paths of first multimedia signals. One of the first multimedia signals may be output to the processor 113, and the processor 113 controls the lcd panel 120 to display. The other path of the first multimedia signal may be output to the cascade device 130 through the HDMI interface.
The beneficial effect of the liquid crystal driving board 110 that this application provided lies in: in the liquid crystal driving board 110 provided by the application, after the first multimedia signal received by the first input interface 111 is copied into multiple paths of first multimedia signals by the signal distributor 112, one path of the multiple paths of first multimedia signals can be output to the liquid crystal display panel 120 for display, the other path of the multiple paths of first multimedia signals can be output to the cascade equipment 130, when the cascade equipment 130 is the same as the liquid crystal driving board 110, each liquid crystal driving board 110 can be in cascade connection with the same first multimedia signal, so that images of the same signal source are transmitted between the liquid crystal driving board 110 and the cascade equipment 130 thereof, and further, different liquid crystal display panels 120 can display the same signal source, and the signal transmission requirement when the liquid crystal display screens are mutually spliced can be met.
In order to enable the liquid crystal driving board 110 to drive different types of liquid crystal display panels 120, in some embodiments, the first output interface 114 may be one of a plurality of display interfaces. Wherein the maximum resolutions supported by the plurality of display interfaces are different from each other.
At this time, the processor 113 may be configured to convert the first multimedia signal into a transmission signal transmitted by a corresponding display interface, and output the transmission signal to the liquid crystal display panel 120 for display through the corresponding display interface. The corresponding display interface is a display interface to which the first output interface 114 belongs among the multiple display interfaces.
By way of example, the various display interfaces described above may include LVDS (Low-Voltage Differential Signaling, low Voltage differential Signaling) signal interfaces and V-By-One (VBO) signal interfaces. The LVDS signal interface can transmit LVDS signals, and the supported maximum resolution is 2K. The V-By-One signal interface can transmit the V-By-One signal, and the supported maximum resolution is 4K. LVDS signals may be connected to the T-CON (Timing Controller) board via a 51PIN electrical cable and V-BY-ONE signals may be connected to the T-CON board via a 51PIN flex cable. The T-CON board may convert the received signal into MINI LVDS to illuminate the liquid crystal display panel 120.
Of course, the multiple display interfaces may also be two different LVDS signal interfaces, where the resolution supported by each LVDS signal interface is different from each other, which is not limited in this application.
Referring to fig. 2, in order to adapt to more kinds of signal sources, the liquid crystal driving panel 110 may further include a second input interface 116 connected to the processor 113 for receiving the second multimedia signal and transmitting the second multimedia signal to the processor 113.
The second input interface 116 may be a DVI (Digital Visual Interface) signal interface, VGA (Video Graphics Array) signal interface, DP (DisplayPort) interface, USB (Universal Serial Bus) interface, or other type of interface. The second multimedia signal transmitted BY the second input interface 116 may be directly supplied to the processor 113, and processed and converted into an LVDS signal or a V-BY-ONE signal BY the processor 113, to drive the 2K or 4K lcd panel 120 to display.
The USB interface may be used as a debug interface, and is externally connected to a debug host computer or a USB disk, and transmits firmware information for upgrading to the processor 113, so as to upgrade the liquid crystal driving board 110.
In order to ensure the quality of the liquid crystal display, in some embodiments, the correction may be performed on the image displayed by the liquid crystal during the liquid crystal display.
Specifically, referring to fig. 3, in some embodiments, at least one of the first input interface 111 and the second input interface 116 is connected to the processing device 140 (it should be understood that fig. 3 shows that the processing device 140 is connected to both the first input interface 111 and the second input interface 116, and in practical applications, the processing device 140 may be connected to only one of the input interfaces). The processing device 140 may be configured to perform a correction process on the original image, and generate and transmit the corrected multimedia signal to the processor through the first input interface 111 and/or the second input interface 116.
Specifically, the original image is a video frame image in the original video. The processing device 140 may generate a correction coefficient, correct optical characteristics such as brightness and chromaticity of the original image by using the correction coefficient, obtain a corrected image, and process the corrected multimedia signal to output to the liquid crystal driving board 110. When the processing device 140 is connected to the liquid crystal driving panel 110 through the first input interface 111, the corrected multimedia signal is input to the processor 113 as a first multimedia signal. When the processing device 140 is connected to the liquid crystal driving panel 110 through the second input interface 116, the corrected multimedia signal is input to the processor 113 as a second multimedia signal.
At this time, the liquid crystal driving board 110 may receive the corrected multimedia signal through the first input interface 111 or the second input interface 116, and process and control the liquid crystal display panel 120 to display through the processor 113.
In other embodiments, referring to fig. 3, at least one of the first input interface 111 and the second input interface 116 is connected to the processing device 140, and the processing device 140 may be configured to generate the correction coefficients.
Accordingly, in some embodiments, the processing device 140 may be configured to transmit the correction coefficients to the processor via the first input interface 111 and/or the second input interface 116. The processor 113 may be configured to perform correction processing on the first multimedia signal or the second multimedia signal according to the correction coefficient.
It is understood that the correction processing is performed on the first multimedia signal or the second multimedia signal according to the correction coefficient, and the correction is performed on the image by using the correction coefficient, so as to correct the optical characteristics such as brightness/chromaticity. The correction processing is performed by the processor 113 in the same manner as the correction processing by applying the correction coefficient, but with a different main body of processing, compared with the direct transmission of the corrected multimedia signal. This correction is also referred to as liquid crystal correction because it acts on the liquid crystal display panel 120.
In some embodiments, the first multimedia signal or the second multimedia signal may also be input synchronously by the processing device 140. When the processing device 140 is connected to the liquid crystal driving panel 110 through the first input interface 111, the uncorrected multimedia signal is input to the processor 113 as a first multimedia signal, and the first input interface 111 may transmit the correction coefficient to the processor 113. When the processing device 140 is connected to the liquid crystal driving panel 110 through the second input interface 116, the uncorrected multimedia signal is input to the processor 113 as a second multimedia signal, and the second input interface 116 may transmit the correction coefficient to the processor 113. In other embodiments, the first multimedia signal or the second multimedia signal may be input by a device other than the processing device 140, which is not limited in this application.
In still other embodiments, referring to fig. 4, the liquid crystal driving panel 110 may further include a third input interface 117 connected to the processing device 140 and the processor 113 (it should be understood that fig. 4 shows that the processing device 140 is connected to the third input interface 117, and in practice, the processing device 140 may be connected to one or more of the first input interface 111 and the second input interface 116 at the same time). The processing device 140 may be used to transmit the correction coefficients to the processor 113 via the third input interface 117. Accordingly, the processor 113 may be configured to perform correction processing on the first multimedia signal and/or the second multimedia signal according to the correction coefficient.
Wherein the third input interface 117 may be a network transmission interface. Similarly, the first multimedia signal or the second multimedia signal is subjected to correction processing based on the correction coefficient, and the image is corrected by the correction coefficient, so that the optical characteristics such as luminance and chromaticity are corrected. The correction processing is performed by the processor 113 in the same manner as the correction processing by applying the correction coefficient, but with a different main body of processing, compared with the direct transmission of the corrected multimedia signal.
The correction coefficient is outputted through the third input interface 117, and the correction coefficient and the multimedia signal can be separately transmitted in cooperation with the input of the multimedia signal through the first input interface 111 or the second input interface 116.
The correction coefficient may be used to correct the optical characteristics of the liquid crystal display panel 120, and may be obtained from display information when the liquid crystal display panel 120 displays a corrected image. The corrected image may be a red, blue, green, white solid image, which may be output by the processor 113 to the liquid crystal display panel 120.
Specifically, the processor 113 may also be configured to output the corrected image to the liquid crystal display panel 120 for display. The liquid crystal display panel 120 may sequentially display the corrected images of red, green, and blue. The liquid crystal display panel 120 is photographed and sampled by a camera, and the photograph is transmitted to the processing device through a USB transmission interface or HDMI. The upper computer correction software of the processing equipment can obtain correction coefficients through algorithm analysis, and the correction coefficients are applied to the original image in the mode to realize correction display.
It should be noted that, besides taking a photograph and sampling by using a camera, the present application may also perform information acquisition on the liquid crystal display panel 120 by using a color temperature instrument, and the related information may be converted into related serial information to be transmitted to the processing device through instrument analysis, so that the upper computer correction software obtains a correction coefficient based on the analysis of the related serial information. This application is not limited thereto.
The upper computer software can transmit the register information related to the correction coefficient to the liquid crystal driving board 110 through the HDMI interface, and the processor 113 of the liquid crystal driving board 110 decodes and displays the register information to realize LCD screen correction, so that the hardware structure link is simpler, and the parameter adjustment is more convenient. Specifically, the processor 113 may include a control chip and a processing chip. The control chip can receive the correction coefficient, decode and analyze the correction coefficient, and transmit the analyzed data to the processing chip. The processing chip can correct the multimedia signal by utilizing the analyzed data.
Referring to fig. 5, in other embodiments, the liquid crystal driving panel 110 may further include a control interface 118 connected to the processor 113. The control interface 118 may be a transmission interface of a level signal, connected to the control device 150, for outputting a first control signal to the control device 150.
Specifically, the control device 150 may include, but is not limited to, a liquid crystal driving panel 110 or a central control device, which may be used to control environmental components in a physical scene.
The number of control interfaces 118 may be one or more.
For example, the control interface 118 may be an RJ45 interface, and may be used to transmit RS232 level signals, so as to implement interaction of control signals with the control device 150. At this time, the processor 113 may include a signal conversion chip and a processing chip, and the processing chip may transmit the first control signal to the signal conversion chip, convert the first control signal to a signal of RS232 level, and output the signal through an RJ45 interface.
In some embodiments, the control interface 118 may also receive a second control signal sent by the control device 150. Likewise, the second control signal sent by the control device 150 may be converted into a specific protocol signal by the signal conversion chip and transmitted to the processing chip for processing.
Specifically, the second control signal may be used to perform at least one of reading back information from the processor 113, adjusting a display effect of the lcd panel 120, and controlling the lcd panel 120 to display an OSD (on-screen display) menu. Taking information readback as an example, after the processor 113 receives the second control signal, the first control signal may be fed back, where the first control signal carries parameter information of the processor 113, for example, a processor state identifier of the processor 113, a resource occupancy rate, and so on. In this manner, information read back of the processor 113 may be accomplished via the control interface 118, with the operating state of the processor 113 being monitored by the control device 150. Taking the example of adjusting the display effect of the lcd panel 120 or controlling the lcd panel 120 to display an OSD menu, the processor 113 may adjust the display effect such as display brightness and three-dimensional display of the lcd panel 120 after receiving the second control signal, and at the same time, may trigger the lcd panel 120 to display the OSD menu. This application is not limited thereto.
Referring to fig. 6, in other embodiments, the liquid crystal driving board 110 may further include a third output interface 119; the third output interface may be an audio output interface. Accordingly, when the first multimedia signal carries an audio signal, the processor 113 is configured to separate the audio signal from the first multimedia signal, and output the audio signal through the third output interface 119.
Similarly, when the second media signal carries an audio signal, the processor 113 may also be configured to separate the audio signal from the second media signal and output the audio signal through the third output interface 119.
For example, when HDMI, DVI, DP inputs audio with audio frequency band, the processor 113 analyzes and separates independent audio frequency, and outputs the independent audio frequency through the third output interface 119, which can be externally connected with audio input devices such as a 3.5mm audio seat, an earphone, a sound box and the like, so as to realize audio playing.
In the embodiment of the application, by setting the first input interface 111 and the second input interface 116 of different types, different video output interfaces can be adapted, and the application is simple and the universality is wide. Meanwhile, the first output interface 114 may be any one of a plurality of display interfaces, so that the user's selection of the lcd panel 120 is more, and is not limited by the lcd panel 120 with a single resolution. In addition, the second output interface 115 is used to realize loop-out, so that one input source can be transmitted among a plurality of cascade-spliced liquid crystal display panels 120, and is provided for different liquid crystal display panels 120 for displaying, and the signal utilization rate is high.
As a specific example, fig. 7 shows a liquid crystal driving panel 110 provided in the present application, including a first input interface 111, a signal distributor 112, a processor 113, a first output interface 114, a second output interface 115, a second input interface 116, a control interface 118, and a third output interface 119. The first input interface 111 is an HDMI interface, and the second input interface 116 includes a DVI signal interface, a VGA signal interface, a DP interface, and a USB interface. The first output interface 114 supports LVDS signal outputs and V-By-One signal outputs. The second output interface 115 is an HDMI interface. The control interface 118 is an RJ45 interface.

The liquid crystal display panel 120 is used for displaying the processed signal transmitted by the liquid crystal driving panel 110. That is, the liquid crystal display panel 120 may display a specific image under the driving of the liquid crystal driving panel 110.
