DETAILED DESCRIPTION

[0052] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0053] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0054] It can be understood that the “connection” in the following embodiments should be understood as “electrical connection”, “communication connection”, etc. if the connected circuits, modules, units, etc. have electrical signals or data transmission between each other.

[0055] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" and the like specify the presence of stated features, wholes, steps, operations, components, parts, or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof. At the same time, the term "and / or" used in this specification includes any and all combinations of the relevant listed items.

[0056] In one embodiment, Figure 1 As shown, a micro display system is provided, which is suitable for a micro display screen that displays in a sequential color manner; it includes: a driving device 100 and a display device 200. The driving device 100 is used to receive, parse and reorganize video sequential color subframe data to obtain reorganized subframe data. The display device 200 is connected to the output end of the driving device 100, and is used to receive and display the reorganized subframe data.

[0057] The principle of sequential color display is to illuminate the RGB three primary colors of light in a certain order to the micro display screen in turn, and use the visual inertia of the human eye to synthesize the rolling three primary colors of light into a color display effect. The advantage of sequential color display is that it has a higher resolution on a display screen of the same size, and no filter film is required in sequential color display, which can simplify the preparation process of the micro display screen and improve light efficiency. Therefore, more and more micro display screens adopt sequential color display.

[0058] The time-series color subframe data includes R subframe, G subframe and B subframe. Figure 2As shown, it is a schematic diagram of an example of the receiving order of sequential color subframe data; the sequential receiving order of the R subframe, the G subframe and the B subframe includes but is not limited to RGBRGB, RRGGBB and RRRGGGBBB.

[0059] Exemplarily, if the video source data is in the form of time-sequential color sub-frame data, the video source data can be directly sent to the micro display system for processing and display.

[0060] For example, if the video source data is in the form of spatial color data, the process of converting the spatial color data into temporal color subframe data is set in a main processor outside the micro display system. The main processor can be one of FPGA (Field Programmable Gate Array), MCU (Microcontroller Unit), CPU (Central Processing Unit), GPU (Graphics Processing Unit), etc.

[0061] The micro display system provided above does not need to set up a storage module for storing one or more frames of spatial color data, nor does it need to set up a conversion unit for converting spatial color data into sequential color subframe data. It directly receives sequential color subframe data for corresponding processing. When implemented in hardware, it has a small area and low power consumption; thus, it can reduce the cost of chip production and the frame delay of chip data processing. The micro display system can be used in display devices that support sequential color, such as LCOS (Liquid Crystal on Silicon), micro LED (micro light-emitting diode), etc.

[0062] The micro display system can display full color, that is, the sequential color subframe data includes R subframe, G subframe and B subframe. The micro display system can also display monochrome, that is, only one of R subframe, G subframe and B subframe; for example, to display green color, the sequential color subframe data refers to G subframe.

[0063] In one embodiment, Figure 3 As shown, a driving device 100 of a micro display system includes a data input interface 110 , a logic analysis module 120 , an optical parameter correction module 130 and a data reorganization output module 140 .

[0064] The data input interface 110 is used to receive sequential color subframe data. The logic analysis module 120 is used to process the sequential color subframe data according to the modulation mode of the display device 200 and the video data transmission protocol to obtain analyzed subframe data. The video data transmission protocol used by the data input interface 110 and the logic analysis module 120 is compatible. The data input interface 110 corresponds to the physical layer of the video data transmission protocol, and the logic analysis module 120 corresponds to the logical layer of the video data transmission protocol.

[0065] In one embodiment, the data input interface 110 includes a MIPI (Mobile Industry Processor Interface) data input interface 111 and an eDP (Embedded DisplayPort) data input interface 112 ; the logic analysis module 120 includes a MIPI logic analysis module 121 and an eDP logic analysis module 122 .

[0066] In one embodiment, the micro display system supports physical interfaces of two video transmission protocols, and performs logical analysis according to the corresponding video transmission protocols. Among them, the MIPI data input interface 111 is connected to the input end of the MIPI logic analysis module 121, and the eDP data input interface 112 is connected to the input end of the eDP logic analysis module 122. Exemplarily, the output end of the MIPI logic analysis module 121 and the output end of the eDP logic analysis module 122 are connected to the input end of the selector 150, and the output end of the selector 150 is connected to the optical parameter correction module 130. The MIPI transmission protocol and the eDP transmission protocol are two high-speed video data transmission protocols.

[0067] The MIPI data input interface 111 is used to receive sequential color subframe data according to the MIPI transmission protocol; for example, Figure 3 As shown, the MIPI data input interface 111 includes a D-PHY (500Mbit / s physical layer) and a DSI (Display Serial Interface) device controller. Among them, D-PHY is an item in the MIPI transmission protocol, which is a high-speed, low-power and source-synchronous physical layer that can support 1-4 data channels. The DSI device controller receives commands in a low-energy, high-speed working mode to meet the needs of video and command display. The MIPI logic parsing module 121 is used to process the timing color subframe data according to the modulation mode of the display device 200 and the MIPI transmission protocol to obtain the parsed subframe data.

[0068] The eDP data input interface 112 is used to receive sequential color subframe data according to the eDP transmission protocol; illustratively, the eDP data input interface 112 includes an eDP Sink (receiver) and an eDP RX (Receiver). The eDP logic parsing module 122 is used to process the sequential color subframe data according to the modulation mode of the display device 200 and the eDP transmission protocol to obtain the parsed subframe data.

[0069] In one embodiment, the micro display system only supports the MIPI transmission protocol, that is, only includes the MIPI data input interface 111 and the MIPI logic parsing module 121 .

[0070] In one embodiment, the micro display system only supports the eDP transmission protocol, that is, only includes the eDP data input interface 112 and the eDP logic parsing module 122 .

[0071] The optical parameter correction module 130 is used to perform optical correction on the analyzed sub-frame data to obtain corrected sub-frame data. Exemplarily, the optical parameter correction module 130 mainly performs optical parameter correction functions such as image brightness, contrast and gamma curve to adjust the display effect of the micro display screen.

[0072] The data reorganization output module 140 is used to process the corrected subframe data according to the display data requirements, obtain the reorganized subframe data, and send the reorganized subframe data to the display device 200. Exemplarily, address encoding is performed according to the scanning method of the micro display screen; custom data is transmitted in the blanking area, for example, special characters are filled in the invalid data to indicate which row of data is currently; a timing control signal is added, etc. The data reorganization output module 140 is specifically designed according to the display data requirements of the display device 200.

[0073] In one embodiment, the display device 200 of the micro-display system is used to display according to the analog amplitude modulation method, and the logic analysis module 120 is used to process the timing color sub-frame data according to the analog amplitude modulation method and the video data transmission protocol to obtain the analyzed sub-frame data; wherein the analyzed sub-frame data is 8-bit single-pixel data.

[0074] In one embodiment, the display device 200 of the micro-display system is used to display according to the digital pulse width modulation method; the logic analysis module 120 is used to process the timing color sub-frame data according to the digital pulse width modulation method and the video data transmission protocol to obtain the analyzed sub-frame data; the analyzed sub-frame data is in a 1-bit single-bit pixel data format.

[0075] In one embodiment, the display device 200 of the micro display system is used for displaying in a hybrid modulation mode, wherein the hybrid modulation mode is a combination of an analog amplitude modulation mode and a digital pulse width modulation mode, and correspondingly, the logic analysis module 120 is used for processing the sequential color sub-frame data in accordance with the hybrid modulation mode and the video data transmission protocol to obtain the analyzed sub-frame data.

[0076] In one embodiment, see Figure 2 The display device 200 of the micro display system includes a data input processing module 210 and a pixel array module 220 .

[0077] The data input processing module 210 is used to receive the reorganized sub-frame data, parse the reorganized sub-frame data according to the display data requirements, and obtain the sub-frame data to be displayed. Exemplarily, the data input processing module 210 is configured to correspond to the data reorganization output module 140 in the driving device 100, parse and process the reorganized sub-frame data, and obtain the sub-frame data to be displayed suitable for the pixel array module 220 to display.

[0078] The pixel array module 220 is used to display the subframe data to be displayed and store the next subframe data to be displayed. In one embodiment, the pixel array module 220 includes a plurality of pixel structures. The pixel structure is a circuit structure corresponding to each pixel point. Exemplarily, when the display device adopts an analog amplitude modulation method, the pixel structure includes a DAC (Digital to analog converter) and a DRAM (Dynamic Random Access Memory). Exemplarily, when the display device 200 adopts a digital pulse width modulation method, the pixel structure includes a SARM (Static Random-Access Memory). The pixel structure also includes a buffer for storing the next subframe data to be displayed.

[0079] In one embodiment, a micro display screen using a sequential color method requires an additional color light source. The micro display system needs to light up the corresponding color luminescent material according to the display time of the reorganized sub-frame data. In one embodiment, the driving device includes a luminescent material lighting module; or the display device includes a luminescent material lighting module; the luminescent material lighting module is used to light up the corresponding color luminescent material according to the illumination time corresponding to the reorganized sub-frame data.

[0080] like Figure 4As shown, it is a schematic diagram of an example of driving time allocation of sequential color subframe data. Taking the RGBRGB subframe receiving sequence as an example, the driving time of a frame period is divided into three subframe periods, and a subframe period includes signal writing time, liquid crystal response time, and illumination time in sequence. According to the allocation of each time period in the subframe period, the display device 200 is controlled to display the subframe data to be displayed and the luminescent material lighting module is controlled to light up the corresponding color luminescent material at the corresponding illumination time.

[0081] In one embodiment, the driving device 100 of the micro display system includes a luminescent material lighting module (not shown in the figure). The luminescent material lighting module is used to light up the corresponding colored luminescent material according to the illumination time corresponding to the reorganized sub-frame data. Exemplarily, the luminescent material lighting module is connected to the output end of the data reorganization output module 140, and generates corresponding lighting data according to the display timing of the reorganized sub-frame data; or, the luminescent material lighting module is a part of the data reorganization data module 140, and is used to generate lighting data of corresponding timing while generating the reorganized sub-frame data. Among them, the lighting data is used to drive the luminescent material of the micro display screen.

[0082] In one embodiment, the luminescent material lighting module is provided in the display device. Exemplarily, the luminescent material lighting module is connected to the output end of the data input processing module 210, and generates corresponding lighting data according to the display timing of the sub-frame data to be displayed; or, the luminescent material lighting module is a part of the data input processing module 210, and is used to generate the lighting data of the corresponding timing while generating the sub-frame data to be displayed.

[0083] In one embodiment, the driving device 100 of the micro display system is implemented with a separate driving chip, and the display device 200 is implemented with a silicon-based backplane. In one embodiment, the driving device 100 and the display device 200 of the micro display system can be integrated together using a smaller process node and implemented with a silicon-based backplane to reduce the volume of the micro display screen and facilitate application.

[0084] The resolution of the video source data that can be supported by the micro display system provided by the above embodiment includes but is not limited to 1280*720, 1280*960, 1920*1080 and 2560*1440.

[0085] It is understandable that the driving device 100 and the display device 200 of the above-mentioned micro display system can also adopt other forms, not limited to the forms mentioned in the above-mentioned embodiments, as long as they can achieve the functions of receiving, parsing, reorganizing and displaying sequential color subframe data.

[0086] The above embodiments provide that the micro display system can be implemented using any appropriate hardware, firmware (e.g., dedicated integrated circuit), software, or a combination of software, firmware, and hardware. For example, the various components of the micro display system can be formed on an integrated circuit (IC) chip or on separate IC chips. In addition, the various components of the micro display system can be implemented on a flexible printed circuit film, a tape carrier package (TCP), a printed circuit board (PCB), or formed on a substrate.

[0087] Based on the same inventive concept, the present application provides a display device. In one embodiment, Figure 5 As shown, a display device is provided, including: a main processor 300, and any one of the micro display systems provided in the above embodiments.

[0088] The main processor 300 is used to receive spatial color data, convert the spatial color data into temporal color subframe data, and send the temporal color subframe data to the micro display system. The micro display system is used to receive and display the temporal color subframe data.

[0089] In one embodiment, the main processor 300 includes a timing data conversion module 310 and a data output interface 320. The timing data conversion module 310 is used to convert spatial color data into timing color sub-frame data, and the data output interface 320 is used to convert the timing color sub-frame data into a form suitable for transmission according to the video data transmission protocol and send it to the micro display system. The timing data conversion module 310 needs to cache at least one frame of spatial color data before it can be converted into the timing color sub-frame data of three RGB sub-frames.

[0090] Corresponding to the data input interface 110 in the driving device 100 in the micro display system, the data output interface 320 includes a MIPI data output interface 321, and / or an eDP data output interface 322. Exemplarily, the MIPI data output interface 321 includes a DSI main controller and a D-PHY; the eDP data output interface 322 includes an eDP TX (Transmitter) and an eDPSource (transmitter). In an embodiment where the data output interface 320 includes both the MIPI data output interface 321 and the eDP data output interface 322, the output end of the timing data conversion module 310 is connected to the MIPI data output interface 321 and the eDP data output interface 322 respectively through a distributor 330.

[0091] In one embodiment, the display device displays the video source data in accordance with the analog amplitude modulation mode and the 1920*1080 resolution display data requirement. Figure 6As shown, it is a schematic diagram of an example of the data structure of sequential color subframe data under analog amplitude modulation. The main processor 300 converts a frame of 1920*1080*24bit spatial color data into three sequential color subframe data, each subframe data has a data volume of 1920*1080*8bit, and sends it to the micro display system through the MIPI data output interface 321 in the order of R subframe, G subframe, and B subframe.

[0092] After the MIPI bottom layer protocol DSI interface of the driving device 100 completes the functions of high-speed reception, low-power reception and low-power transmission, the MIPI logic parsing module 121 receives the time-series color sub-frame data, adjusts the format of the pixel data, that is, adjusts the bit width to 8-bit single pixel data, and obtains the parsed sub-frame data. The optical parameter correction module 130 adjusts the optical related parameters for the parsed sub-frame data to obtain the corrected sub-frame data. The data reorganization output module 140 reorganizes the data structure of the corrected sub-frame data according to the display data requirements of the display device 200, obtains the reorganized sub-frame data, sends it to the display device 200, and generates the lighting data for driving the luminescent material. After the display device 200 receives the reorganized sub-frame data, the data input processing module 210 processes the reorganized sub-frame data to obtain the sub-frame data to be displayed; the ADC in the pixel array module 220 converts the sub-frame data to be displayed in the digital signal format into an analog signal, stores it in the DRAM, and then displays it at the display time of the next sub-frame.

[0093] Among them, the D-PHY physical layer interface in the MIPI transmission protocol can support 1-4 data channels, that is, the MIPI logic analysis module 121 can receive sequential color subframe data of various data bit widths, including but not limited to 32bit, 24bit, 16bit and 8bit, and the bit width needs to be adjusted to 8-bit single pixel data. Taking 4 data channels as an example, according to the MIPI transmission protocol, the allocation and fusion of data in the 4 data channels are based on the premise of 32bit bit width, and 1 32bit data corresponds to 4 monochrome subframe data, which is split into 4 8-bit monochrome subframe single pixel data.

[0094] In one embodiment, the display device displays the video source data according to the digital pulse width modulation method and the 1280*720 resolution display data requirement. The digital pulse width modulation method is to divide a sequential color subframe data into several parts, and the lighting time of each part corresponds to a different weight value, and different gray levels are generated by the combination of weight values. The pulse width time corresponding to each sequential color subframe data corresponds to the weight value of the pixel bit.

[0095] like Figure 7As shown, it is a schematic diagram of an example of the data structure of sequential color subframe data under digital pulse width modulation. The main processor 300 converts a frame of 1280*720*3*n bit spatial color data to obtain three sequential color subframe data; the data volume of each sequential color subframe data is 1280*720*n bit, and is sent to the micro display system through the eDP data output interface 322 in the order of R subframe, G subframe, and B subframe. The eDP logic analysis module 122 in the driving device 100 decodes the data according to the eDP transmission protocol and analyzes the sequential color subframe logic in the data channel.

[0096] Different from the previous embodiment, the eDP logic parsing module 122 adjusts the bit width to 1-bit single-bit data, such as Figure 7 As shown, n bit data realizes 2^n grayscale levels. A monochrome subframe display time is divided into 2^n times. Time 0 outputs grayscale data bit0, and the display weight corresponding to bit0 is 1. Time 1 and 2 output grayscale data bit1, and the corresponding weight is 2. Time 3 to 6 output grayscale data bit2, and the corresponding weight is 4. By analogy, the display weight corresponding to bit(n-1) is 2^(n-1). It can be understood that each subframe data after parsing is divided into multiple monochrome single-bit subframe data.

[0097] The driving device 100 reorganizes the data structure and sends it to the display device 200 according to the display data requirements of the display device 200, and generates lighting data for driving the luminescent material to light up. The display device 200 receives the reorganized subframe data in a 1-bit single-bit pixel data format, stores it in the corresponding pixel structure, and displays it in the next subframe display time.

[0098] Among them, the receiving order of each single-bit subframe data is not fixed. For example, it can be in the order of bit0 to bit(n-1), or in the order of bit(n-1) to bit0. The receiving order of the single-bit subframe data can also be designed based on the receiving format of the data input processing module 210 of the display device 200 and the data reorganization output module 140.

[0099] In one embodiment, a method for displaying time-sequential color subframe data is provided, which is used to control any one of the micro-display systems provided in the above embodiments.

After the display device 200 receives the reorganized sub-frame data, the data input processing module 210 processes the reorganized sub-frame data to obtain the sub-frame data to be displayed; the ADC in the pixel array module 220 converts the sub-frame data to be displayed in the digital signal format into an analog signal, stores it in the DRAM, and then displays it at the display time of the next sub-frame.

[0104] Step 902: The main processor 300 receives spatial color data, converts the spatial color data into temporal color sub-frame data, and sends the temporal color sub-frame data to the micro display system.

[0105] Step 904: The micro display system receives and displays the sequential color sub-frame data.

The eDP data input interface 112 of the driving device 100 receives the sequential color subframe image in the order of R subframe, G subframe, and B subframe; the eDP logic parsing module 122 parses and processes the sequential color subframe image to obtain parsed subframe data in a 1-bit single-bit pixel data format; the optical parameter correction module 130 performs brightness, contrast, and gamma curve corrections on the parsed subframe data to obtain corrected subframe data; the data reorganization output module 140 reorganizes the data structure of the corrected subframe data according to the display data requirements of the display device 200 to obtain the reorganized subframe data, sends it to the display device 200, and generates lighting data for driving the luminescent material. The display device 200 receives the reorganized subframe data in a 1-bit single-bit pixel data format, and the data input processing module 210 processes the reorganized subframe data to obtain the subframe data to be displayed, and then stores it in the pixel structure in the pixel array module 220, and displays it at the display time of the next subframe.
