[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.
[0021] In related technologies, Mini TVs are common home display devices, and balancing display performance with cost control has always been a core challenge in industry research and development. Currently, there are two main types of Mini TVs on the market. One is the standard Mini TV model, which does not use QD (Quick Dimming) color gamut films, thus controlling costs, but suffers from poor color gamut performance, failing to meet users' demands for high-quality color display. The other is the RGB Mini TV model, which improves color gamut performance through an RGB pixel backlight structure, but suffers from low brightness and color crosstalk. Furthermore, most current RGB Mini TV models rely on increased hardware configurations or custom chip manufacturer support, leading to increased production costs and making it difficult to achieve a balance between performance and cost.
[0022] According to the first aspect of this application, referring to Figure 1 This application provides a display method, which includes: S100: Analyze the information on the screen to be displayed and obtain the current parameters.
[0023] S200 converts the current parameters into red light duty cycle parameter Rd, green light duty cycle parameter Gd, and blue light duty cycle parameter Bd.
[0024] S300: Based on the design parameters of the lamp panel assembly 3, calculate the brightness ratio of red light, green light and blue light, and obtain the red light separation coefficient m, green light separation coefficient n and blue light separation coefficient p based on the brightness ratio of the three.
[0025] S400: Based on the red light duty cycle parameter Rd and the red light separation coefficient m, obtain the actual red light current parameter R'; based on the green light duty cycle parameter Gd and the green light separation coefficient n, obtain the actual green light current parameter G'; based on the blue light duty cycle parameter Bd and the blue light separation coefficient p, obtain the actual blue light current parameter B'.
[0026] The RGB chip of S500 and lamp board assembly 3 displays based on the actual current parameter R' of red light, the actual current parameter G' of green light, and the actual current parameter B' of blue light.
[0027] In this embodiment, the current parameters are obtained by parsing the information of the screen to be displayed, and the current parameters are converted into duty cycle parameters of red light, green light and blue light. Based on the design parameters of the lamp board assembly 3, the separation coefficients of red light, green light and blue light are obtained. The actual current parameters of red light, green light and blue light are obtained through the duty cycle parameters and separation coefficients. Thus, the display brightness can be improved, the color crosstalk problem can be improved, and the dual optimization of color and brightness can be achieved.
[0028] It is understandable that the information to be displayed is the image information that the display device wants to display. Based on different images, the current parameters of the lamp board assembly 3 in the display device are different. The current parameters are parsed and converted into red light duty cycle parameter Rd, green light duty cycle parameter Gd, and blue light duty cycle parameter Bd, thereby obtaining the emission parameters of red, green, and blue light respectively. In this process, based on the design parameters of the lamp board assembly 3, the brightness ratio of red, green, and blue light is calculated, and the red light separation coefficient m, green light separation coefficient n, and blue light separation coefficient p are obtained according to the brightness ratio. Then, based on the red light duty cycle parameter Rd and the red light separation coefficient m, the actual red light current parameter R' is obtained; based on the green light duty cycle parameter Gd and the green light separation coefficient n, the actual green light current parameter G' is obtained; and based on the blue light duty cycle parameter Bd and the blue light separation coefficient p, the actual blue light current parameter B' is obtained. Therefore, by adjusting the current density of red, green, and blue light in the above manner, we can eliminate the risk of color crosstalk on the one hand, and better adjust the luminous characteristics of the fused light on the other hand, so as to eliminate the drawback of insufficient luminous brightness.
[0029] Based on the display method in this application embodiment, the problems of color bleeding and insufficient brightness can be solved without increasing hardware costs or relying on the technical support of the chip manufacturer, thereby achieving dual optimization of color and brightness and a dual breakthrough in product performance upgrade and industry technological innovation.
[0030] When the RGB chip of the light panel component 3 displays based on the actual current parameters R' of red light, G' of green light, and B' of blue light, it can output a blended white light. The brightness of this blended white light can be increased by more than 30%, and there is no color crosstalk problem. This solves the color crosstalk and insufficient brightness problems that are difficult to overcome in the RGB Mini TV industry. At the same time, it takes into account the color gamut performance and achieves dual optimization of color and brightness.
[0031] This embodiment achieves dual optimization of color and brightness by altering the display method. This display method can be programmed into the RGB allocation algorithm module of the backlight controller 2, thus breaking through technical barriers without relying on the original manufacturer's technical support for the backlight controller 2 chip. Simultaneously, it can adaptively change parameters to suit different target models based on various real-world needs. Furthermore, it does not involve hardware changes to the motherboard 1, backlight controller 2, or lamp board assembly 3. Software innovation overcomes hardware limitations, providing a new technical path for performance optimization in the Mini TV industry, achieving a dual breakthrough in product performance upgrades and industry technological innovation. Moreover, since there is no additional hardware investment, there is no need to introduce high color gamut QD films or other hardware components, greatly controlling production costs.
[0032] In some embodiments, the lamp panel assembly 3 has multiple display zones, and the process of parsing the information of the image to be displayed and obtaining current parameters includes: The display information of each display partition is analyzed to obtain the corresponding current parameters of each display partition.
[0033] Understandably, the lamp panel assembly 3 has multiple display zones, and the display effect of each display zone can be independently controlled through methods such as local empty light and zoned light control. Based on the analysis of the image information to be displayed in each display zone, the corresponding current parameters of each display zone are obtained. Each display zone executes steps S200 to S500 based on its own current parameters.
[0034] It should be noted that the specific methods for parsing the information on the screen to obtain the current parameters can be found in relevant technologies, and this application will not elaborate on them in detail.
[0035] In some embodiments, converting the current parameters into red light duty cycle parameter Rd, green light duty cycle parameter Gd, and blue light duty cycle parameter Bd includes: Compare the sum of the current parameters of all display zones with the preset parameters; In response to the sum of the current parameters of each display zone being less than a preset parameter, each current parameter is converted into its corresponding red light duty cycle parameter Rd, green light duty cycle parameter Gd, and blue light duty cycle parameter Bd; in response to the sum of the current parameters of each display zone being greater than or equal to the preset parameter, each current parameter is corrected to obtain a corresponding corrected parameter, and each corrected parameter is converted into its corresponding red light duty cycle parameter Rd, green light duty cycle parameter Gd, and blue light duty cycle parameter Bd.
[0036] Understandably, before converting the current parameters to red light duty cycle parameters Rd, green light duty cycle parameters Gd, and blue light duty cycle parameters Bd, the sum of the current parameters of all display zones is compared with preset parameters to determine if the overall current exceeds the limit. When the overall current does not exceed the limit, the sum of the current parameters of each display zone is less than the preset parameter. In this case, each current parameter is directly converted to its corresponding red light duty cycle parameter Rd, green light duty cycle parameter Gd, and blue light duty cycle parameter Bd. When the overall current exceeds the limit, the sum of the current parameters of each display zone is greater than or equal to the preset parameter. In this case, directly using this current parameter to perform subsequent processes would pose a safety risk. The current parameters need to be corrected to obtain corrected parameters, and each corrected parameter is converted to its corresponding red light duty cycle parameter Rd, green light duty cycle parameter Gd, and blue light duty cycle parameter Bd.
[0037] It should be noted that the preset parameter is a safety threshold parameter. The sum of the current parameters for all display zones is compared to this safety threshold parameter. If the sum of the current parameters is less than the safety threshold, directly performing subsequent steps using each current parameter will not pose a safety risk, and each current parameter can be converted into its corresponding red light duty cycle parameter Rd, green light duty cycle parameter Gd, and blue light duty cycle parameter Bd. If the sum of the current parameters is greater than or equal to the safety threshold, directly performing subsequent steps using each current parameter will pose a safety risk, and therefore, each current parameter needs to be corrected first to ensure that the sum of the corrected parameters is less than the preset parameter.
[0038] In some embodiments, the value of the preset parameter may vary depending on the display device. This application does not limit the specific value of the preset parameter.
[0039] In some embodiments, the correction parameters are obtained in the following manner: The ratio of the sum of the preset parameters and the current parameters is used as the correction coefficient, and the product of each current parameter and the correction coefficient is used as the correction parameter corresponding to each current parameter.
[0040] It is understandable that the ratio of the sum of the preset parameters and the current parameters can be used as a correction coefficient. By multiplying each current parameter by the correction coefficient, the correction parameter corresponding to each current parameter can be obtained.
[0041] For example, the ratio of the preset parameter to the sum of the current parameters is k, and the current parameters are X1, X2, ..., Xn. Therefore, the corrected parameters are kX1, kX2, ..., kXn.
[0042] In some embodiments, the lamp panel assembly 3 is electrically connected to the power board and the backlight controller 2, and the preset parameters are determined based on at least one of the design parameters of the lamp panel assembly 3, the design parameters of the power board, and the design parameters of the backlight controller 2.
[0043] It is understandable that the values of the preset parameters differ depending on the display device. Therefore, each display device can determine its corresponding preset parameters based on at least one design parameter of its lamp board assembly 3 and power board backlight controller 2.
[0044] The preset parameters are determined by the coordinated design parameters of the lamp board assembly 3, the power supply board, and the backlight controller 2.
[0045] For example, the design parameters of the lamp panel assembly 3 can be directly used as preset parameters. For instance, the rated current parameter or rated power parameter of the lamp panel assembly 3 can be directly used as preset parameters.
[0046] For example, preset parameters can be obtained by coordinating the design parameters of the power supply board and the backlight controller 2. For instance, the difference between the rated current parameter of the power supply board and the rated current parameter of the backlight controller 2 can be used as the preset parameter, or the difference between the rated power parameter of the power supply board and the rated power parameter of the backlight controller 2 can be used as the preset parameter.
[0047] For example, the design parameters of the lamp board assembly 3, the power supply board, and the backlight controller 2 are coordinated to obtain preset parameters. For instance, reference parameters are determined based on the size, rated power, and rated current of the lamp board assembly 3, and calibration parameters are determined based on the size, rated power, and rated current of the power supply board and the backlight controller 2. The reference parameters and calibration parameters are combined to obtain the preset parameters. The combination of reference parameters and calibration parameters includes, but is not limited to, operations such as multiplication, division, addition, and subtraction.
[0048] In some embodiments, the design parameters of the lamp panel assembly 3 include the size parameters of the lamp panel assembly 3, and / or, the rated power parameters of the lamp panel assembly 3, and / or, the rated current parameters of the lamp panel assembly 3; and / or, the design parameters of the power board include the size parameters of the power board, and / or, the rated power parameters of the power board, and / or, the rated current parameters of the power board; and / or, the design parameters of the backlight controller 2 include the size parameters of the backlight controller 2, and / or, the rated power parameters of the backlight controller 2, and / or, the rated current parameters of the backlight controller 2.
[0049] It is understandable that the design parameters of the lamp panel assembly 3 are determined by at least one of the three parameters: the size parameters of the lamp panel assembly 3, the rated power parameters of the lamp panel assembly 3, and the rated current parameters of the lamp panel assembly 3.
[0050] For example, the rated power parameter of the lamp panel assembly 3 can be directly used as the design parameter of the lamp panel assembly 3, or the rated current parameter of the lamp panel assembly 3 can be directly used as the design parameter of the lamp panel assembly 3.
[0051] For example, the rated power and rated current parameters of the lamp panel assembly 3 are calculated based on the size parameters of the lamp panel assembly 3. The rated power parameters of the lamp panel assembly 3 can be directly used as the design parameters of the lamp panel assembly 3, or the rated current parameters of the lamp panel assembly 3 can be directly used as the design parameters of the lamp panel assembly 3.
[0052] For example, a preset coefficient is obtained based on the size parameters of the lamp panel assembly 3, and the product of the preset coefficient and the rated power parameters and / or rated current parameters of the power board is used as the design parameters of the lamp panel assembly 3.
[0053] The design parameters of a circuit board are determined by at least one of the following: the circuit board size parameters, the circuit board rated power parameters, and the circuit board rated current parameters.
[0054] For example, the rated power parameter of the circuit board can be directly used as the design parameter of the circuit board, or the rated current parameter of the circuit board can be directly used as the design parameter of the circuit board.
[0055] For example, the rated power and rated current parameters of the circuit board are calculated from the circuit board size parameters. The rated power parameters or the rated current parameters of the circuit board can then be directly used as the design parameters for the circuit board.
[0056] For example, a preset coefficient is obtained based on the circuit board size parameters, and the product of the preset coefficient and the rated power parameters and / or rated current parameters of the power board is used as the design parameters of the circuit board.
[0057] The design parameters of the backlight controller 2 are determined by at least one of the following: the size parameters of the backlight controller 2, the rated power parameters of the backlight controller 2, and the rated current parameters of the backlight controller 2.
[0058] For example, the rated power parameter of the backlight controller 2 can be directly used as the design parameter of the backlight controller 2, or the rated current parameter of the backlight controller 2 can be directly used as the design parameter of the backlight controller 2.
[0059] For example, the rated power parameters and rated current parameters of the backlight controller 2 are calculated from the size parameters of the backlight controller 2. The rated power parameters of the backlight controller 2 can be directly used as the design parameters of the backlight controller 2, or the rated current parameters of the backlight controller 2 can be directly used as the design parameters of the backlight controller 2.
[0060] For example, a preset coefficient is obtained based on the size parameters of the backlight controller 2, and the product of the preset coefficient and the rated power parameters and / or rated current parameters of the power board is used as the design parameters of the backlight controller 2.
[0061] In some embodiments, based on the design parameters of the lamp panel assembly 3, the brightness ratios of red, green, and blue light are calculated, and the red light separation coefficient m, green light separation coefficient n, and blue light separation coefficient p are obtained based on these brightness ratios, including: Based on the information of the image to be displayed and the design parameters of the lamp board assembly 3, the output wavelength and luminous efficiency of the light to be output are obtained. Based on the output wavelength and luminous efficiency of the light to be output, and combined with the mapping table, the brightness ratios of red, green and blue light in the RGB chip are obtained; The red light separation coefficient m, green light separation coefficient n, and blue light separation coefficient p are obtained based on the brightness ratio of the three.
[0062] It is understandable that after obtaining the output wavelength and luminous efficiency of the light to be output through the information of the screen to be displayed and the design parameters of the lamp board component 3, the brightness ratio of red light, green light and blue light is obtained directly by looking up a table. Then, based on the brightness ratio of the three, the red light separation coefficient m, the green light separation coefficient n and the blue light separation coefficient p are obtained.
[0063] In some embodiments, the mapping table contains the correspondence between the output wavelength and luminous efficiency of light and the brightness ratios of red, green, and blue light, thereby allowing the direct acquisition of the brightness ratios of red, green, and blue light based on the mapping table. For example, mapping tables include the DCI-P3 standard table and the BT.2020 standard table. For instance, in the DCI-P3 standard table, the core ratio weights of red, green, and blue light under standard D65 white light are: Y = 0.2225R + 0.7169G + 0.0606. The corresponding brightness ratios of red, green, and blue light are 0.2225:0.7169:0.0606 ≈ 3.7:11.8:1.
[0064] In some embodiments, the red light separation coefficient m, green light separation coefficient n, and blue light separation coefficient p are obtained based on the brightness ratio of the three, including: The light panel assembly 3 plays red, green, and blue pure color fields based on the information of the screen to be displayed in order to obtain the test brightness ratio of red, green, and blue light; In response to the test brightness ratio being the same as the brightness ratio of red, green, and blue light, the current ratio coefficients of the current of red, green, and blue light in the lamp panel assembly 3 are used as the red light separation coefficient m, the green light separation coefficient n, and the blue light separation coefficient p, respectively. In response to the test brightness ratio being different from the brightness ratio of red, green, and blue light, the current ratios of red, green, and blue light in the lamp panel assembly 3 are adjusted until the test brightness ratio is the same as the brightness ratio of red, green, and blue light. Then, the current ratio coefficients of the current of red, green, and blue light in the lamp panel assembly 3 are used as the red light separation coefficient m, the green light separation coefficient n, and the blue light separation coefficient p, respectively.
[0065] Understandably, when the lamp panel assembly 3 plays red, green, and blue pure color fields, the test brightness ratio of red, green, and blue light in the current state of the lamp panel assembly 3 can be obtained. If this test brightness ratio is the same as the brightness ratio of red, green, and blue light calculated based on the design parameters of the lamp panel assembly 3 in the aforementioned method, then the current ratio coefficients of red, green, and blue light in the current state of the lamp panel assembly 3 are directly used as the red light separation coefficient m, the green light separation coefficient n, and the blue light separation coefficient p, respectively. For example, if the current ratio of red, green, and blue light in the current state is 1:4:12, then the current ratio coefficients of red, green, and blue light are 1, 4, and 12, respectively, and m is taken as 1, n as 4, and p as 12.
[0066] If the tested brightness ratio differs from the red, green, and blue light brightness ratio calculated based on the design parameters of the lamp panel assembly 3 in the aforementioned method, the instrument can be calibrated based on the light emission of the lamp panel assembly 3. This can be achieved by changing the current ratio of red, green, and blue light in the lamp panel assembly 3 to alter the brightness ratio of the three light sources. Once the current ratio of red, green, and blue light in the lamp panel assembly 3 is changed until the tested brightness ratio matches the original brightness ratio, the current ratio coefficients of red, green, and blue light in the current state of the lamp panel assembly 3 are used as the red light separation coefficient m, green light separation coefficient n, and blue light separation coefficient p, respectively. For example, before the current ratio adjustment, the current ratio of red, green, and blue light is 1:5:11. In this case, the tested brightness ratio differs from the red, green, and blue light brightness ratio calculated based on the design parameters of the lamp panel assembly 3 in the aforementioned method. As the current ratio is adjusted, the test brightness ratio becomes the same as the brightness ratio of red, green and blue light calculated based on the design parameters of the lamp board assembly 3 in the aforementioned method. Then, the current ratio of red, green and blue light is corrected to 1:4:12, and the correction is completed. At this time, m takes the value of 1, n takes the value of 4, and p takes the value of 12.
[0067] In some embodiments, the actual current parameter R' of red light is obtained based on the red light duty cycle parameter Rd and the red light separation coefficient m; the actual current parameter G' of green light is obtained based on the green light duty cycle parameter Gd and the green light separation coefficient n; and the actual current parameter B' of blue light is obtained based on the blue light duty cycle parameter Bd and the blue light separation coefficient p, including: The actual current parameter R' of red light is obtained based on the ratio of the red light duty cycle parameter Rd to the red light separation coefficient m; the actual current parameter G' of green light is obtained based on the ratio of the green light duty cycle parameter Gd to the green light separation coefficient n; and the actual current parameter B' of blue light is obtained based on the ratio of the blue light duty cycle parameter Bd to the blue light separation coefficient p.
[0068] It is understandable that R'=Rd / m, G'=Gd / n, and B'=Bd / p. Therefore, the actual current parameters R' (red light), G' (green light), and B' (blue light) can be quickly calculated. The RGB chip in lamp panel assembly 3 displays based on the actual current parameters R' (red light), G' (green light), and B' (blue light), ensuring that the red, green, and blue light are blended before display, with crosstalk error controlled within 0.1%, guaranteeing accurate color display.
[0069] According to the second aspect of this application, such as Figure 2As shown, a display device is provided. The display device includes a motherboard 1, a backlight controller 2, and a lamp board assembly 3. The backlight controller 2 is electrically connected to the motherboard 1, and the lamp board assembly 3 is electrically connected to the backlight controller 2. The backlight controller 2 includes an RGB allocation algorithm module, which is configured to execute the display method as described in the foregoing embodiments.
[0070] Understandably, the lamp board assembly 3 is used for display, and the main board 1 is used to control the backlight controller 2 and output power to the backlight controller 2. After the RGB allocation algorithm module executes the display method, it obtains the current parameters by parsing the information of the image to be displayed, and converts the current parameters into duty cycle parameters for red, green, and blue light. Based on the design parameters of the lamp board assembly 3, it obtains the separation coefficients of red, green, and blue light. Through the duty cycle parameters and separation coefficients, it obtains the actual current parameters of red, green, and blue light. Thus, the display brightness can be improved, the color crosstalk problem can be reduced, and dual optimization of color and brightness can be achieved.
[0071] In some embodiments, the motherboard 1 adopts a 9612 SOC motherboard 1, the backlight controller 2 adopts a 9800 Bcon board, the RGB allocation algorithm module is integrated into the 9800 Bcon board, the light strip assembly is an RGB Mini TV standard light strip, and uses an RGB chip, which is an RGB three-color backlight bead.
[0072] It should be noted that after the hardware connection of the display device is completed, the software system that can execute the display method in the aforementioned embodiments needs to be implanted into the RGB allocation algorithm module of the backlight controller 2, so that the RGB allocation algorithm module can execute the display method as in the aforementioned embodiments.
[0073] In some embodiments, the software system can be written in C language. Of course, it can also be written in programming languages such as Python, Java, and C++ to execute the display methods in the foregoing embodiments.
[0074] In some embodiments, the display performance of the display method can be verified by running the display device. Specifically, after powering on the display device, the motherboard 1 supplies power to the backlight controller 2, and the RGB allocation algorithm module of the backlight controller 2 loads the display method and enters the working state. A test color signal is input to the display device. After receiving the signal, the backlight controller 2 obtains the actual current parameters R' (red light), G' (green light), and B' (blue light) through the algorithm of the display method. The LED strip assembly displays based on these parameters, thereby outputting a blended white light to avoid color crosstalk. Testing of this blended white light shows that its brightness is more than 30% higher than that of traditional RGB Mini TV models, and its color gamut coverage reaches over 95% of DCI-P3, with no obvious color crosstalk. After 72 hours of continuous operation, the display device maintains stable performance, with no degradation in brightness and color performance, and the color crosstalk control effect consistently meets the standards. It is evident that the technology can reliably achieve dual optimization in color and brightness for RGB Mini TV models without additional hardware costs, making it suitable for mass production and widespread adoption.
[0075] Based on the above verification, it can be seen that the display method in the aforementioned embodiment can be directly embedded into the RGB allocation algorithm module of the backlight controller 2 after programming, without the need to introduce other hardware. Therefore, there is no need to make large-scale modifications to the existing RGB Mini TV production line, which has broad promotional value and market competitiveness, and can promote the large-scale popularization of RGB Mini TV models.
