Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a display device and its control method. Background Technology

[0002] With the rapid advancement of display technology, semiconductor component technology, which is the core of display devices, has also made leaps and bounds. For existing display devices, organic light-emitting diodes (OLEDs), as current-driven light-emitting devices, are increasingly being used in high-performance display fields due to their characteristics such as self-emission, fast response, wide viewing angle, and ability to be fabricated on flexible substrates.

[0003] In the fabrication of OLED display filters, three sub-pixels—red (R), green (G), and blue (B)—are typically used to form a pixel. Multiple of these pixels are arranged in a matrix to create the filter. Therefore, the visual resolution perceived by a user while viewing the display is its physical resolution (actual resolution), which is the maximum number of pixels the screen can display. Currently, displays show images at fixed resolutions and cannot be switched, making it difficult to meet practical needs. Summary of the Invention

[0004] The purpose of this application is to provide a display device and its control method, which changes the problem that the resolution of the display device cannot be changed after the hardware is fixed, enhances the practical application of the product, and increases the applicability of the product.

[0005] This application discloses a display device, which includes a display panel and a driving component. The display panel has multiple parallel data lines, multiple parallel scan lines, and multiple light-emitting modules arranged in an array along the data lines and scan lines. Each light-emitting module includes multiple light-emitting units arranged in an array. In each light-emitting module, the light-emitting units in each row or column emit different colors. All light-emitting units in the same row of a light-emitting module are designated as first pixels, and all light-emitting units in the same column of a light-emitting module are designated as second pixels. The driving component is connected to the display panel and drives the display panel. The driving component includes a first display module, a second display module, and a switching component. The switching component is connected to both the first and second display modules and controls one of the first and second display modules to drive the display panel. When the first display module is used for display, it drives the first pixels in each light-emitting module to display. When the second display module is used for display, it drives the second pixels in each light-emitting module to display.

[0006] Optionally, the light-emitting units in each light-emitting module are arranged in a 3*3 matrix, with the light-emitting units in the first row emitting red, green, and blue, the light-emitting units in the second row emitting green, blue, and red, and the light-emitting units in the third row emitting blue, red, and green.

[0007] Optionally, the size of each of the light-emitting units in the data line direction is the same as the size in the scan line direction.

[0008] Optionally, the projection pattern of the light-emitting unit on the light-emitting surface of the display panel includes a square, a circle, or a regular hexagon.

[0009] Optionally, the driving component includes a core board, a timing control chip, a data driving circuit, and a scanning driving circuit. The data driving circuit is connected to the data lines in the display panel, and the scanning driving circuit is connected to the scan lines in the display panel. The core board receives front-end data and converts it into display data. The timing control chip is connected to the core board, the data driving circuit, and the scanning driving circuit, respectively, receives the display data, and drives the light-emitting unit through the data driving circuit and the scanning driving circuit. The first display module, the second display module, and the switching component are all located within the core board.

[0010] Optionally, the mainboard includes a conversion module, a first display module, a second display module, and a switching component. The conversion module receives front-end data and converts the front-end data into a data signal. The first display module and the second display module are respectively connected to the conversion module. The first display module converts the data signal into first display data, and the second display module converts the data signal into second display data. The switching component includes a selector, a switching module, and a signal receiver. The selector is respectively connected to the first display module, the second display module, and the timing control chip. One end of the switching module is connected to the selector, and the other end is connected to the signal receiver. The switching module selects to output either the first display data or the second display data to the timing control chip according to the switching signal output by the signal receiver.

[0011] Optionally, the display device further includes a controller, which is disposed on the housing of the display device or serves as a remote control device for the display device; the controller is matched with the signal receiver and issues switching commands to the signal receiver.

[0012] Optionally, the mainboard includes a conversion module, a first display module, a second display module, and a switching component. One end of the switching component is connected to the conversion module, and the other end is connected to both the first and second display modules. The first and second display modules are also connected to the timing control chip. The conversion module receives front-end data and converts the front-end data into a data signal. The switching component outputs the data signal to either the first or the second display module.

[0013] This application also discloses a control method for a display device, used to control the display device as described above, the control method comprising the steps of:

[0014] Issuing switching commands to the display device; and

[0015] The switching component in the display device receives the switching command and selects either the first display module to drive the display panel to display at a first resolution or the second display module to drive the display panel to display at a second resolution, according to the switching command.

[0016] Specifically, when the display panel displays at a first resolution, all light-emitting units in the same row of the light-emitting module constitute one pixel; when the display panel displays at a second resolution, all light-emitting units in the same column of the light-emitting module constitute one pixel.

[0017] Optionally, before the step of issuing a switching command to the display device, the following step is also included:

[0018] Turn on the display device;

[0019] The conversion module in the mechanism board receives front-end data and converts it into data signals; and

[0020] The first display module and the second display module respectively receive the data signal and convert the data signal into corresponding first display data and second display data;

[0021] In the step of receiving the switching instruction and selecting the first display module to drive the display panel to display at a first resolution or selecting the second display module to drive the display panel to display at a second resolution, the switching component selects to output the first display data or the second display data to the timing control chip according to the switching instruction.

[0022] This application modifies the arrangement of light-emitting units in the display panel, changing the traditional method where only three light-emitting units in the same row can form a pixel. Instead, multiple light-emitting units in the same row and multiple light-emitting units in the same column can form a single pixel. Combined with two display modules and a switching module in the driving component, this allows the display panel to display two resolution modes. The first resolution mode uses a first display module to control the display panel to display a first pixel composed of multiple light-emitting units in the same row. The second resolution mode uses a second display module to control the display panel to display a first pixel composed of multiple light-emitting units in the same column. Compared to the first resolution mode, the second resolution mode increases the number of pixels in the scan line direction and decreases the number of pixels in the data line direction, thus presenting a different resolution. Because the display device in this application can select between two resolutions, it enhances the practical application scope and increases the product's applicability. Furthermore, since the light-emitting units of different colors in the display panel are arranged alternately in the same column and row, it effectively solves the problem of left-right color shift caused by interference between different colored light-emitting units.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] The present application will now be described in detail with reference to the accompanying drawings and optional embodiments.

[0034] Example 1:

[0035] like Figure 1 As shown, Figure 1 This is a schematic diagram of a display device provided in an embodiment of this application. In this embodiment, the display device 10 includes a display panel 100 and a driving component 200. The display panel 100 is provided with a plurality of parallel data lines 110, a plurality of parallel scan lines 120, and a plurality of light-emitting modules 130 arranged in an array along the data lines 110 and the scan lines 120. Each light-emitting module includes a plurality of light-emitting units 134 arranged in an array.

[0036] In this application embodiment, the type of the display device 10 is not limited. When the display panel 100 is a liquid crystal panel, the light-emitting unit 134 is a color resist; when the display panel 100 is a mini LED display panel or a Micro LED display panel, the light-emitting unit 134 is an LED lamp bead; when the display panel 100 is an organic light-emitting diode (OLED) display panel, the light-emitting unit 134 is a light-emitting material layer.

[0037] In the light-emitting module 130, the light-emitting units 134 in each row or column emit different colors. For example, when a pixel is composed of red, green, and blue light-emitting units 134, the light-emitting module 130 contains nine light-emitting units 134, and these light-emitting units 134 are arranged in a 3x3 matrix. As an example of the arrangement of light-emitting units 134 within one type of light-emitting module 130, see... Figure 2 As shown, the light-emitting units 134 in the first row are red light-emitting unit 131, green light-emitting unit 132, and blue light-emitting unit 133, respectively; the light-emitting units 134 in the second row are green light-emitting unit 132, blue light-emitting unit 133, and red light-emitting unit 131, respectively; and the light-emitting units 134 in the third row are blue light-emitting unit 133, red light-emitting unit 131, and green light-emitting unit 132, respectively. Of course, the light emission colors of the first row of light-emitting units 134 can also be red-blue-green, blue-red-green, blue-green-red, green-red-blue, and green-blue-red. Moreover, when the light emission color of the first row of light-emitting units 134 is red-green-blue, the light emission color of the second row of light-emitting units 134 can be a combination of green-blue-red and blue-red-green. The light emission color of the third row of light-emitting units 134 will be fixed by the first and second rows. That is, if the first row is red-green-blue and the second row is green-blue-red, then the third row can only be blue-red-green. According to the permutation and combination, when a pixel is composed of light-emitting units 134 of three colors, red, green, and blue, there are a total of 12 ways to arrange the light-emitting units 134 in the light-emitting module 130.

[0038] Similarly, when a pixel is composed of black and white light-emitting units 134, the light-emitting module 130 contains 4 light-emitting units 134, and these light-emitting units 134 are arranged in a 2*2 matrix. There are a total of 2 ways to arrange the light-emitting units 134 in the light-emitting module 130.

[0039] When a pixel is composed of light-emitting units 134 of four colors, namely red, green, blue and white or red, green, blue and yellow, the light-emitting module 130 contains 16 light-emitting units 134, and these light-emitting units 134 are arranged in a 4*4 matrix. There are a total of 288 ways to arrange the light-emitting units 134 in the light-emitting module 130.

[0040] Regarding the selection of pixel type and the arrangement of light-emitting units 134 within the light-emitting module 130 in this application embodiment, the specific selection can be made according to actual needs and is not limited here. For ease of explanation, the following description will take a pixel composed of light-emitting units 134 of three colors: red, green, and blue as an example.

[0041] After the light-emitting units 134 in the light-emitting module 130 are arranged as described above, since all the light-emitting units 134 (red, green and blue light-emitting units 134) in each row and each column of the light-emitting module 130 can be regarded as a pixel unit, here, all the light-emitting units 134 in the same row of the light-emitting module 130 are taken as the first pixel 140, and all the light-emitting units 134 in the same column of the light-emitting module 130 are taken as the second pixel 150.

[0042] Furthermore, the driving component 200 is connected to the display panel 100 and drives the display panel 100. The driving component 200 includes a first display module 250, a second display module 260, and a switching component 270. The switching component 270 is connected to the first display module 250 and the second display module 260 respectively, controlling one of the first display module 250 and the second display module 260 to drive the display panel 100. When the first display module 250 is used for display, the first display module 250 drives each of the display modules 100. When the first pixel 140 in the light-emitting module 130 is displayed, that is, when the display panel 100 is displayed, it is displayed by multiple light-emitting units 134 (red, green and blue light-emitting units 134) in the same row forming pixels; when the second display module 260 is used for display, the second display module 260 drives the second pixel 150 in each of the light-emitting modules 130 to be displayed, that is, when the display panel 100 is displayed, it is displayed by multiple light-emitting units 134 (red, green and blue light-emitting units 134) in the same column forming pixels.

[0043] This application changes the arrangement of the light-emitting units 134 in the display panel 100, changing the traditional method where only three light-emitting units 134 in the same row can form a pixel in the display panel 100, to a method where multiple light-emitting units 134 in the same row can form a pixel, and multiple light-emitting units 134 in the same column can also form a pixel. Combined with the two display modules and the switching module 272 in the driving component 200, the display panel 100 has two resolution display modes. The first resolution display mode is controlled by the first display module 250 to display the first pixel 140 composed of multiple light-emitting units 134 in the same row. The second resolution display mode is controlled by the second display module 260 to display the first pixel 140 composed of multiple light-emitting units 134 in the same column.

[0044] For example, the pixels in the display panel 100 are composed of red, green, and blue light-emitting units 134. The number of light-emitting units 134 in each row of the display panel 100 is 3H, and the number of light-emitting units 134 in each column is V. When the first display module 250 is used for display at the first resolution, the number of pixels in each row of the display panel 100 is H, and the number of pixels in the display panel 100 is H*V, that is, the resolution of the display panel 100 at this time is H*V. When the second display module 260 is used for display at the second resolution, the number of pixels in each column of the display panel 100 is V / 3, and the number of pixels in the display panel 100 is 3H*V / 3, that is, the resolution of the display panel 100 at this time is 3H*V / 3.

[0045] It can be seen that the resolution of the display panel 100 is different when displaying at the first resolution and the second resolution. Compared with the first resolution display method, the number of pixels in the direction of the scan line 120 increases and the number of pixels in the direction of the data line 110 decreases in the second resolution display method.

[0046] Since the display device 10 in this application can select two resolutions for display, and the display device 10 can switch the resolution at any time during use, and the resolution switching is performed after the hardware in the display device 10 is fixed, the actual application field of the product can be enhanced and the applicability of the product can be increased.

[0047] Furthermore, since the light-emitting units 134 of various colors in the display panel 100 are arranged alternately in the same column and row, the left-right color shift problem caused by interference between different color light-emitting units 134 can be effectively solved. Specifically, taking the existing display panel 100 with light-emitting units 134 of red, green, and blue arranged in the same row as an example, since each column of light-emitting units 134 uses the same color, when viewed from the left, red appears redder because it is closer to the human eye, and when viewed from the right, blue appears bluer because it is closer to the human eye. This phenomenon is more pronounced for mini-LED or Micro-LED display technologies, as the LED light-emitting beads are not planar but convex. However, in this embodiment, the color of the light-emitting units 134 in each column and row is different, so that no matter which side of the display panel 100 the human eye looks from, no one color will appear more obvious, thus overcoming this color shift problem.

[0048] Taking a liquid crystal panel as an example, in a traditional liquid crystal display panel 100, the length and width of the color resist are inconsistent, and the color resist is generally rectangular. However, this application changes the shape of the light-emitting unit 134 so that the size of each light-emitting unit 134 in the direction of the data line 110 is the same as the size in the direction of the scan line 120, that is, the length and width of the light-emitting unit 134 are the same. In this way, no matter whether the display device 10 switches to the first resolution display state or the second resolution display state, the length and width of the pixels are consistent in both states, thereby avoiding display problems such as color shift and changes in screen ratio after resolution switching.

[0049] like Figure 3 The diagram shows a square light-emitting unit 134, but the light-emitting unit 134 can also be a circle, a regular hexagon, or other shapes. In other words, the projection pattern of the light-emitting unit 134 on the light-emitting surface of the display panel 100 includes a square, a circle, or a regular hexagon. Furthermore, the spacing 'a' between two adjacent light-emitting units 134 in the same row is equal to the spacing 'b' between two adjacent light-emitting units 134 in the same column, further ensuring the display effect.

[0050] Regarding the specific design of the driver component 200 in the embodiments of this application, such as Figure 4 The diagram shown is a schematic of the driving component 200 in an embodiment of this application. The driving component 200 includes a core board 210, a timing control chip 220, a data driving circuit 230, and a scanning driving circuit 240. The data driving circuit 230 is connected to the data line 110 in the display panel 100, and the scanning driving circuit 240 is connected to the scan line 120 in the display panel 100. The core board 210 receives front-end data m and converts the front-end data m into display data n. The timing control chip 220 is connected to the core board 210, the data driving circuit 230, and the scanning driving circuit 240, respectively, receives the display data n, and drives the light-emitting unit 134 through the data driving circuit 230 and the scanning driving circuit 240. The first display module 250, the second display module 260, and the switching component 270 are all disposed in the core board 210.

[0051] Compared to the approach of placing the resolution switching components within the timing control chip 220, this embodiment places all resolution switching components within the chassis board 210. This allows for signal switching to be completed in the initial stage after the front-end data m is received, avoiding the increased workload of data processing that occurs when display data is converted into drive data by the timing control chip 220 before switching. Furthermore, the chassis board 210 has more space, making design modifications easier without needing to adjust its dimensions, thus preventing cost increases.

[0052] Specifically, the mechanism board 210 includes a conversion module 274, a first display module 250, a second display module 260, and a switching component 270. The conversion module 274 receives front-end data m and converts the front-end data m into a data signal p. The first display module 250 and the second display module 260 are respectively connected to the conversion module 274. The first display module 250 converts the data signal p into first display data p1, and the second display module 260 converts the data signal p into second display data p2.

[0053] The switching component 270 includes a selector 271, a switching module 272, and a signal receiver 273. The selector 271 is connected to the first display module 250, the second display module 260, and the timing control chip 220, respectively. The difference between the first display module 250 and the second display module 260 and those in existing display devices is that, in this embodiment, the first display module 250 and the second display module 260 adaptively adjust the display data according to the pixel arrangement in the display panel 100.

[0054] The selector 271, a commonly used data selector in the field of signal transmission, works by selecting and transmitting data from multiple channels to a single common data channel, thus realizing the data selection function of the logic circuit.

[0055] The switching module 272 employs an analog-to-digital converter (ADC), with one end connected to the selector 271 and the other end connected to the signal receiver 273. The switching module 272 selects to output either the first display data or the second display data to the timing control chip 220 according to the switching signal output by the signal receiver 273.

[0056] The conversion module 274, the first display module 250, the second display module 260 and the selector 271 are mounted on the system-on-a-chip (SOC) 211 of the chassis board 210. The switching module 272 and the signal receiver 273 are located outside the system-on-a-chip 211 and are connected to each other.

[0057] In this embodiment, the first display module 250 and the second display module 260 synchronously receive the same front-end data and simultaneously convert the front-end data into corresponding display data. Both send the display data to the selector 271. When a resolution mode is selected, the selector 271 directly sends out the corresponding signal for direct display, instead of converting the corresponding display data after selecting the resolution mode. This avoids display delay and frame drops after switching resolutions, thereby improving the display effect.

[0058] Furthermore, the display device 10 also includes a controller 280, which is matched with the signal receiver 273 and issues a switching command e to the signal receiver 273. Specifically, the controller 280 can be disposed on the housing of the display device 10 and used as a button, allowing the user to manually press the button to switch resolutions; the controller 280 can also be used as a remote control device for the display device 10, or as a control button on a traditional remote control, allowing for direct remote switching; of course, the controller 280 can also be used as a control program on the display interface, allowing switching to be performed on the interface when using the display device 10.

[0059] Correspondingly, such as Figure 5 As shown, this application embodiment also discloses a control method for the above-described display device 10, including the following steps:

[0060] S1: Issues a switching command to the display device;

[0061] S2: The switching component in the display device receives the switching instruction and selects the first display module to drive the display panel to display at a first resolution, or selects the second display module to drive the display panel to display at a second resolution, according to the switching instruction;

[0062] When the display panel 100 displays at a first resolution, all light-emitting units 134 in the same row of the light-emitting module 130 form a pixel; when the display panel 100 displays at a second resolution, all light-emitting units 134 in the same column of the light-emitting module form a pixel.

[0063] Specifically, before step S1, the following steps are also included:

[0064] S01: Turn on the display device;

[0065] S02: The conversion module in the mechanism board receives front-end data and converts the front-end data into data signals;

[0066] S03: The first display module and the second display module respectively receive the data signal and convert the data signal into corresponding first display data and second display data;

[0067] In step S02, the conversion module 274 receives front-end data from a data source such as a USB flash drive or optical fiber. In step S2, the switching component 270 selects to output either the first display data or the second display data to the timing control chip 220 according to the switching instruction. As one illustrative example, the switching module 272 receives a switching signal, i.e., an analog signal, from the controller 280. At this time, the switching module 272 converts the analog signal into a digital signal with high and low values, 0 or 1. When the resolution switching signal is 0, the selector 271 selects the first display module 250 to drive the display panel 100 to display at the first resolution. When the resolution switching signal is 1, it selects the second display module 260 to drive the display panel 100 to display at the second resolution.

[0068] Example 2:

[0069] like Figure 6 The diagram shown is a schematic of a display device provided in the second embodiment of this application. The difference from the first embodiment lies in the design of the core board 210. Specifically, the core board 210 includes a conversion module 274, a first display module 250, a second display module 260, and a switching component 270. One end of the switching component 270 is connected to the conversion module 274, and the other end is connected to both the first display module 250 and the second display module 260. The first display module 250 and the second display module 260 are also connected to the timing control chip 220. The conversion module 274 receives front-end data and converts the front-end data into display data. The switching component 270 outputs the display data to either the first display module 250 or the second display module 260.

[0070] In this embodiment, after selecting the resolution switching mode, one of the first display module 250 and the second display module 260 is used to process the display data, instead of keeping the first display module 250 and the second display module 260 working continuously as in the first embodiment. This reduces the workload of the display modules and reduces power consumption.

[0071] It should be noted that the limitations of each step involved in this solution are not considered as limiting the order of steps, provided that they do not affect the implementation of the specific solution.
