Description

Technical Field

[0001] The present invention relates to the field of display control technology, and in particular to a method and system for controlling image display on a special-shaped LED display screen. Background Art

[0002] With the rapid development of LED display technology, special-shaped LED displays have received widespread attention in advertising, stage design, and architectural integration. Therefore, the image display control of special-shaped LED displays has become particularly important in the manufacturing process of display devices. Conventional methods usually use traditional image processing technology based on rectangular grids to rasterize the largest enclosing rectangular area outside the special-shaped screen to obtain a regular grid. Then, through a preset pixel mapping table, the data of the virtual regular grid points is allocated to the corresponding physical LED lamp beads for screening, and the invalid area data is shielded. The screened valid pixel data is sent to the drive circuit to realize image display.

[0003] However, conventional methods still have significant limitations when dealing with image control of special-shaped LED displays. Due to the non-orthogonal characteristics of the geometric shape of the special-shaped screen, they are often limited to forcibly fitting the special-shaped structure into a rectangular grid frame, resulting in geometric distortion and failing to fully utilize the potential advantages of the special-shaped screen. In addition, the pixel positions of the displayed image cannot be accurately aligned with the physical arrangement of the actual special-shaped screen, resulting in distortion and deformation of the image edges. At the same time, it only reflects pixel mapping at the electrical signal level and cannot compensate for the physical distortion of light field propagation under irregular geometric structures to achieve spatial deformation correction.

[0056] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0057] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0058] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0059] Reference Figures 1 to 4 , is an embodiment of the present invention, which provides a method for controlling image display on a special-shaped LED display screen, comprising the following steps:

[0060] S1. Obtain image data of a special-shaped LED display screen and analyze the RGB color value of the image data.

[0061] During the display device manufacturing process, a standard image file parsing library is used to access the signal input interface of the special-shaped LED display and obtain the image data of the special-shaped LED display;

[0062] Among them, the image data contains the color information of each pixel, and the image data is stored in standard image formats such as JPEG, PNG and RAW;

[0063] Using the metadata reading function of the standard image file parsing library, compare the image data with the display requirements of the special-shaped LED display screen to verify whether the format of the image data meets the display requirements of the special-shaped LED display screen;

[0064] If the image data format does not match, it is converted to the supported RGB format through the parsing library to generate format-verified image data;

[0065] Display requirements include image file format, resolution, and bit depth information; for example, JPEG and PNG image formats, 1920 × 1080 resolution, and 24-bit RGB bit depth;

[0066] Preprocess the image data after format verification to generate a brightness-balanced pixel matrix;

[0067] Preprocessing includes denoising, geometric correction, and brightness equalization, as follows:

[0068] The Gaussian blur filter method is used to perform a convolution operation on the image data after format verification to remove the noise of the image data and generate a denoised pixel matrix. Specifically:

[0069] Extract the pixel matrix from the format-verified image data. The pixel matrix includes the color information of each pixel, that is, the chromaticity values of the red, green, and blue channels, ranging from 0 to 255. For example, the chromaticity value of a pixel is (120, 150, 180);

[0070] Use historical image data to set the Gaussian blur filter template and determine the denoising filter area;

[0071] The Gaussian blur filter template is a two-dimensional array of a fixed size, such as a 3×3 area;

[0072] Using the Gaussian blur filter method, traverse each pixel position in the pixel matrix, starting from the upper left corner and moving row by column, select the current pixel and its surrounding neighboring pixels to form a denoising filter area of the same size as the Gaussian blur filter template, for example, a 3×3 area;

[0073] In the denoising filter area, the corresponding pixel chromaticity values of the red, green and blue channels are weighted summed with the template value to obtain the new chromaticity values of the red, green and blue channels as the denoised chromaticity values of the current pixel;

[0074] Store the denoised chroma values at the corresponding pixel locations, update the pixel matrix, and repeat the steps until all pixels are traversed, resulting in a complete denoised pixel matrix.

[0075] Among them, the denoised pixel matrix stores the denoised chroma values of the red, green and blue channels;

[0076] The denoised pixel matrix is geometrically corrected to remove the distortion caused by the non-planar geometric shape (such as curved and irregular shapes) of the special-shaped LED display.

[0077] The process of geometric correction is as follows:

[0078] Get the spatial coordinates of each pixel and the corresponding red, green, and blue channel chromaticity values from the denoised pixel matrix. For example, a pixel with coordinates of (50, 100) has a chromaticity value of (122, 140, 170).

[0079] Read the geometric mapping table of the special-shaped LED display screen. The geometric mapping table stores the correspondence between the physical coordinates of the irregular shape of the special-shaped LED display screen and the plane pixel coordinates. For example, the plane coordinate (50, 100) is mapped to the curved surface physical coordinate (48, 102);

[0080] It should be noted that the geometric mapping table refers to the correspondence formed by measuring the geometric structure of the display device (such as the surface shape and physical coordinates of the surface) using a laser scanner during the display device manufacturing process, and matching the spatial coordinates of the pixels with the physical coordinates of the surface of the geometric structure;

[0081] Among them, the display device refers to a special-shaped LED display screen;

[0082] Traverse each pixel position in the denoising pixel matrix and extract the plane coordinates of the current pixel;

[0083] Find the physical coordinates of the curved surface corresponding to the current plane coordinates in the geometric mapping table to determine the coordinates of the actual display position of the pixel on the special-shaped LED display screen;

[0084] Reassign the chromaticity values of the pixels in the denoised pixel matrix to the new coordinate positions according to the physical coordinates of the surface;

[0085] If multiple plane coordinates are mapped to the same surface physical coordinate, the average of the pixel chromaticity values is used as the chromaticity value of the new coordinate. For example, if the red channel chromaticity values of two pixels are 122 and 124 respectively, the average value is 123;

[0086] If some surface physical coordinates do not have corresponding plane coordinates, the chromaticity values of adjacent pixels are used for interpolation filling. For example, the red channel chromaticity value of the new coordinate (49, 101) is 123.

[0087] Integrate the reallocated pixel coordinates and chromaticity values to generate a geometrically corrected pixel matrix;

[0088] For example, the pixel coordinates of the denoised pixel matrix are queried through the geometric mapping table of the special-shaped LED display, and the new actual coordinates are reallocated to generate the geometrically corrected pixel matrix;

[0089] Using the histogram equalization method, histograms are created for the red, green, and blue channels respectively; the histogram is used to record the number of pixels that appear at each chromaticity value;

[0090] The number of pixels in the red, green, and blue channels of the geometrically corrected pixel matrix is counted, and the proportion of the number of pixels of each chromaticity value and the following chromaticity values in the total number of pixels is calculated to obtain the cumulative distribution function values of the red, green, and blue channels. The formula is:

[0091]

[0092] Among them, D represents the cumulative distribution function value, H represents the number of pixels corresponding to the chromaticity value i, and N i Represents the total number of chroma pixels, i represents the index variable of the chroma value, It means summing the chromaticity values from 0 to c, where c represents the current chromaticity value;

[0093] Based on the cumulative distribution function value of each channel, the RGB value of each pixel is updated to balance the brightness distribution in the geometric correction pixel matrix, generate a brightness-balanced pixel matrix, and eliminate brightness deviations caused by uneven light sources and sensor differences;

[0094] Parse the brightness equalization pixel matrix and extract and normalize the RGB color value of each pixel as follows:

[0095] Traverse each pixel position in the brightness equalization pixel matrix, starting from the upper left corner and moving row by row and column by column, read the red, green, and blue values of the current pixel position, and record them as RGB chromaticity value triples; for example, the RGB chromaticity value is (12, 15, 18);

[0096] Perform linear normalization on the red, green, and blue chromaticity values, mapping the 0-255 range to the 0-1 range. For example, the red channel chromaticity value of 12 is normalized to 0.047.

[0097] The normalized red, green, and blue values are recorded as standardized RGB chromaticity values; for example, the standardized RGB chromaticity values are (0.047, 0.059, 0.071);

[0098] Map the standardized RGB color value to the current pixel position to ensure the consistency of color information on different devices;

[0099] Repeat the steps until all pixels in the brightness equalization pixel matrix are traversed to generate the standardized RGB chromaticity values of all physical pixels;

[0100] It should be noted that display device manufacturing refers to the full industrial production process of optoelectronic integration and calibration parameter burning, based on optoelectronic parameter and structural design (such as the microcavity array and electrode arrangement of special-shaped screens), through roll-to-roll lithography to produce flexible circuits, inkjet printing to achieve precise quantum dot arrays, and vacuum gas injection bonding to seal the inert gas chamber;

[0101] Furthermore, the inert gas ionization characteristic data is obtained by collecting the breakdown field strength of different gas ratios Ne:Ar during the packaging process of special-shaped LED display manufacturing;

[0102] The optical path difference of special-shaped LED display refers to the manufacturing tolerance of substrate curvature radius and thickness during the manufacturing process of special-shaped LED display, which is used to construct the optical path difference compensation matrix.

[0103] S2. Convert the RGB chromaticity value into the quantum dot energy level control parameter and calculate the control signal of the quantum dot energy level transition.

[0104] Use the data interface to obtain the standardized RGB chromaticity values in the standardized pixel matrix;

[0105] The normalized pixel matrix is stored in a two-dimensional array, and each pixel element is a normalized RGB color value ranging from 0 to 1.

[0106] Traversing each pixel position of the verified standardized pixel matrix, reading the standardized RGB chromaticity value of the corresponding pixel position, and generating a standardized RGB chromaticity set;

[0107] Based on the quantum dot luminescence principle, a quantum dot energy level control parameter mapping table is constructed to map the standardized RGB chromaticity values to quantum dot energy level control parameters;

[0108] The quantum dot energy level control parameters include the quantum dot energy level structure, base voltage, and target excitation wavelength value; for example, the standardized RGB chromaticity values (0.961, 0.518, 0.024) are mapped to the quantum dot energy level structure (red energy level E1, green energy level E2, blue energy level E3), base voltage (3.0V, 2.8V, 2.5V), and target excitation wavelength value (625nm, 520nm, 470nm);

[0109] Using the quantum dot energy level control parameter mapping table, searching for the standardized RGB chromaticity value of each pixel in the standardized RGB chromaticity value set, converting it into the corresponding quantum dot energy level control parameter, and generating a quantum dot energy level control parameter set;

[0110] It should be noted that the quantum dot energy level control parameter mapping table is set using the spectrum test results of the quantum dot coating;

[0111] Based on the quantum dot energy level structure and target excitation wavelength value in the quantum dot energy level control parameter set, determining the quantum dot energy level offset of each pixel and generating a quantum dot energy level offset set;

[0112] For example, the target excitation wavelength value of 625nm is compared with the standard energy level wavelength of 620nm, and the energy level-wavelength sensitivity of the quantum dot material is combined to generate the quantum dot energy level offset;

[0113] Based on the basic voltage and quantum dot energy level offset in the quantum dot energy level control parameters, the basic voltage is adjusted to compensate for the quantum dot energy level offset to generate a driving voltage value;

[0114] For example, a base voltage of 3.0V combined with the quantum dot energy level offset and the electrical response characteristics of the quantum dot material generates a driving voltage value of 3.1V;

[0115] Integrate the quantum dot energy level offset and driving voltage value, pair the quantum dot energy level offset and driving voltage value of each pixel, and generate a control signal for the quantum dot energy level transition;

[0116] Check the integrity of the control signal of the quantum dot energy level transition, confirm that the size of the control signal is consistent with the resolution of the special-shaped LED display, and generate a verified control signal for the quantum dot energy level transition.

[0117] S3. Convert the control signal into an electric pulse signal to drive the quantum dot coating of the special-shaped LED display to perform directional electron transition and generate an electron distribution state.

[0118] Extracting quantum dot energy level offset and driving voltage value from the control signal of quantum dot energy level transition;

[0119] The quantum dot energy level offset and driving voltage value are used to analyze the control signal of the quantum dot energy level transition and generate the effective action time window of the control signal, as follows:

[0120] Use the driving voltage value to query the response characteristics of the quantum dot material and determine the basic energy level transition time;

[0121] Based on the quantum dot energy level offset, the additional time for energy level transition is calculated using the following formula:

[0122]

[0123] Where t represents the additional time of energy level transition, E represents the quantum dot energy level offset, q represents the energy level-voltage sensitivity, and V represents the driving voltage value;

[0124] Integrate the basic energy level transition time and the additional energy level transition time to generate the effective action time of the control signal;

[0125] Repeat the above steps to determine the effective action time of all control signals and integrate them into an effective action time window;

[0126] The effective action time window is used to time-segment the driving voltage value of the control signal to generate discrete signal segments;

[0127] The pulse width, pulse amplitude and pulse interval are calculated based on the discrete signal segments and combined into an electrical pulse signal. The formula is:

[0128] P = (A, W, G);

[0129] A=V j ;

[0130]

[0131] Where P represents the electrical pulse signal, A represents the pulse amplitude (unit: volt), W represents the pulse width (unit: second), G represents the pulse interval (unit: second), V j Indicates the driving voltage value of the discrete signal segment (unit: volt), T represents the effective time window (unit: second), N j represents the total number of discrete signal segments (integer), f represents the refresh frequency of the driving circuit (unit: Hz), and j represents the index variable of the discrete signal segment;

[0132] Among them, pulse width refers to the duration of a discrete signal segment, pulse amplitude refers to the driving voltage value of a discrete signal segment, and pulse interval refers to the time gap between adjacent discrete signal segments;

[0133] Query the unique address identifier of the physical pixel in the electrode position database to generate a set of driving electrode coordinates;

[0134] The electrode position database refers to the physical layout record of the electrode array during the manufacturing process of the special-shaped LED display. The electrode position database includes the pixel resolution of the special-shaped LED display and the physical position of the electrode;

[0135] Aggregating the electrical pulse signals based on the driving electrode coordinates to generate an electrical pulse signal matrix;

[0136] Input the electric pulse signal matrix into the electrode array driving circuit of the special-shaped LED display screen;

[0137] The driving circuit applies an electric signal to the electrode array of the quantum dot coating according to the pulse width, amplitude and interval of the electric pulse signal matrix;

[0138] The electrical signal excites the quantum dots in the quantum dot coating, causing directional electronic transitions and generating excited state distributions;

[0139] Furthermore, quantum dot coating refers to a nano-semiconductor material layer (such as a ZnS core-shell structure) formed on the surface of a substrate through a precision coating process (such as inkjet printing) during the display device manufacturing process. The electron particle size is controlled within the range of 3-5 nanometers, and high-purity RGB primary colors are excited through the quantum confinement effect during the electric drive circuit process. The aluminum oxide barrier layer is encapsulated through atomic layer deposition technology ALD to isolate water and oxygen corrosion.

[0140] Use photodiodes to detect excited state distribution and obtain electron density data;

[0141] The electron density data is converted into electron distribution states using pre-calibrated photoelectric conversion coefficients.

[0142] S4. Calculate optical compensation parameters based on the electron distribution state and convert them into an ionization path matrix. Use the ionization path matrix to modulate the ionized inert gas of the special-shaped LED display to form a plasma cloud.

[0143] Read the electronic distribution state through the data interface;

[0144] Using the quantum dot luminescence principle, the influence of electron distribution state on luminous intensity is analyzed to determine the brightness correction coefficient (unit: cd / m 2 / electronic);

[0145] It should be noted that the principle of quantum dot luminescence refers to the process in which electrons in nanoscale semiconductor quantum dots are excited by an electric field, transitioning from a ground state to an excited state and then returning to the ground state, releasing photons of specific wavelengths, thereby producing high-purity red, green, and blue primary colors of light.

[0146] The process of analyzing the effect of electron distribution on luminous intensity is:

[0147] Traverse the electron distribution state and read the electron density value of each physical pixel row by row and column by column, that is, the number of electrons per unit volume of each physical pixel;

[0148] Using the principle of quantum dot luminescence, we can obtain the luminescence intensity values corresponding to different electron density values. That is, we can determine the luminescence intensity by using the energy of photons released when electrons return from the excited state to the ground state. For example, the electron density value is 1000 cd / m 2 / electrons correspond to a luminous intensity of 10 candela / square meter;

[0149] The target luminous intensity value is set using the brightness standard in the manufacturing process of special-shaped LED displays. For example, the target luminous intensity value is 12 candelas / square meter.

[0150] Compare the luminous intensity value with the target luminous intensity value and calculate the brightness correction coefficient, that is, the ratio of the target luminous intensity value to the luminous intensity value;

[0151] Based on the electron distribution state, the optical compensation parameters of each physical pixel are calculated using the formula:

[0152] Optical compensation parameter = electron distribution state × brightness correction coefficient;

[0153] The ionization path parameters are determined using historical inert gas ionization characteristic data of special-shaped LED displays;

[0154] Historical noble gas ionization characteristic data refers to the relationship between electric field strength and ionization path;

[0155] Ionization path parameters include the electric field direction and intensity range;

[0156] Integrate the electric field direction and intensity range to generate a power path mapping table;

[0157] The electric path mapping table is used to match the ionization path parameters corresponding to each optical compensation parameter, define the electric field distribution of the ionization electrode array, and generate an ionization path matrix;

[0158] The ionization path matrix is input into the ionization electrode driving circuit, and the ionization electrode driving circuit uses the ionization path parameters to dynamically modulate the voltage and frequency in the ionization electrode array of the special-shaped LED display screen to generate the electric field distribution of the ionization electrode array;

[0159] The electric field distribution of the ionization electrode array is input into the driving circuit of the high-frequency electric field, and the electric field direction and electric field intensity value of the electric field distribution are extracted;

[0160] According to the electric field strength value, the driving circuit generates a corresponding high-frequency voltage signal, for example, a strength of 500 volts / meter generates a high-frequency voltage of 5 volts;

[0161] According to the electric field direction value, the driving circuit adjusts the phase of the voltage signal to ensure that the electric field direction is consistent with the ionization path. For example, a direction of 45 degrees corresponds to a phase shift of 45 degrees.

[0162] The generated high-frequency voltage signal is applied to the corresponding electrodes of the ionization electrode array, covering the inert gas area of the special-shaped LED display screen, and exciting the inert gas (such as neon and argon) to ionize and generate a plasma cloud.

[0163] S5.
