Description

Technical Field

[0001] The present application relates to the technical field of display products, and in particular to a spliced ​​display screen and a control method thereof. Background Art

[0002] Splicing an LCD (Liquid Crystal Display) screen with an LED (light-emitting diode) screen is a common large-screen display method. The LCD screen has a border outside that does not have a display function. By covering the strip-shaped LED screen on the border of the LCD screen, seamless splicing can be achieved.

[0003] However, in the prior art, a driver chip performs cascade control on multiple LED display screens to control the refresh of the LED display screens. This method causes multiple LED display screens to start refreshing at the same time, and it is impossible to control the refresh mode of each LED display screen separately. In addition, since the amount of data displayed on the LED display screen is less than the amount of data displayed on the LCD display screen, the refresh speed of the LED display screen is faster and the refresh speed of the LCD display screen is slower. In one frame, the LED display screen completes the refresh earlier than the LCD display screen. The refresh of the LCD display screen and the LED display screen in one frame is not synchronized, making it difficult to achieve the effect of synchronous refresh while realizing seamless splicing. In dynamic pictures, it is easy to see the picture dislocation phenomenon. Summary of the invention

DETAILED DESCRIPTION

[0046] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article, unless otherwise specified, generally indicates that the associated objects before and after are in an "or" relationship.

[0048] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0049] The present application proposes a spliced ​​display screen and a control method thereof, so as to realize synchronous refreshing of an LCD display area and an LED display area while satisfying seamless splicing.

[0050] A spliced ​​display screen and a control method thereof provided by the present application are introduced below in conjunction with the accompanying drawings.

[0051] Please refer to Figure 1 , Figure 1 1 is a schematic diagram of the structure of a spliced ​​display screen provided in an exemplary embodiment of the present disclosure, comprising: at least two LCD display modules 1 arranged along a first direction X, each LCD display module 1 comprising an LCD display area 11, and a splicing area 12 between adjacent LCD display areas 11; at least one LED display module 2, each LED display module 2 comprising an LED display area 21 and an LED fan-out area 22 arranged along a second direction Y, the LED display area 21 being located in the splicing area 12 (not shown), and the second direction Y is different from the first direction X.

[0052] The following is a detailed description with reference to the accompanying drawings.

[0053] In some embodiments, see Figure 2 As shown, Figure 2 1 is a schematic diagram of the structure of an LCD display module provided in an exemplary embodiment of the present disclosure, wherein the LCD display module 1 comprises an LCD display area 11 and an edge portion 13 located at the periphery of the LCD display area 11, wherein the edge portion 13 does not have a display function. The portion of the edge portion 13 arranged along the second direction Y is used as a first edge area 131, and the portion of the edge portion 13 arranged along the first direction X is used as a splicing area 12.

[0054] In some embodiments, the LED display module 2 includes at least one of the following: a MicroLED display module and a MiniLED display module. The MicroLED display module includes a Micro Light Emitting Diode Display (Micro LED) display area. The Micro LED display area is a display screen obtained by arraying LED chips with a size ranging from 1 micron to 10 microns. The MiniLED display module includes a sub-millimeter light-emitting diode (Mini LED) display area, which is a display screen obtained by arraying LED chips with a size ranging from 100 microns to 300 microns.

[0055] In some embodiments, the number of LCD display modules 1 can be increased along the first direction X, and the number of LED display modules 2 can be increased along the second direction Y. There is a splicing area 12 between two adjacent LCD display areas 11. The LED display area 21 in the LED display module 2 is arranged in the splicing area 12, which can realize the scalability of the spliced ​​display screen.

[0056] In some embodiments, the first direction X is perpendicular to the second direction Y.

[0057] In some embodiments, see Figure 1 As shown, the number of LED display modules 2 is 2. The two LED display modules 2 are arranged along the second direction Y; part of the edge of the LED display area 21 of the two LED display modules 2 overlaps with the edge of the splicing area 12, and the LED display area 21 covers the splicing area 12. The LED fan-out areas 22 of the two LED display modules 2 are located outside the splicing area 12 and the LCD display area 11, and the two LED fan-out areas 22 are respectively arranged on different sides of the LCD display module 1. The LED display area 21 and the LCD display area 11 form a complete display area. The LED fan-out area 22 is used to lay out pin routing and fan-out routing. Specifically, the LED fan-out area 22 is arranged on one side of the first edge area 131, and further, the two LED fan-out areas 22 can be arranged in the first edge area 131.

[0058] In some embodiments, each LED display module 2 includes an LED display area 21 and an LED fan-out area 22. Each LED display module can independently control the refresh direction, refresh time, and refresh sequence, and thus can control the LED display module and the LCD display module to refresh synchronously. In the same frame, the LCD display area 11 and the LED display area 21 can start refreshing and end refreshing at the same time in the same direction, which is beneficial to eliminate the picture misalignment phenomenon. Furthermore, the LED fan-out area 22 is arranged on one side edge of the LED display area 21, realizing a three-sided borderless design of the LED display module 2. When splicing, the LED display area 21 is used to cover the splicing area 12 and the partial edge of the LED display area 21 is controlled to overlap with the edge of the splicing area 12, which can make up for the defect that the splicing area 12 has no display function, so that the spliced ​​display screen forms a complete display area, and realizes seamless splicing between the LCD display area 11 and the LED display area 21. The LED fan-out area 22 without display function is arranged outside the splicing area 12 and the LCD display area 11, which can avoid the LED fan-out area 22 from blocking the LED display area 21 and the LCD display area 11, thereby improving the display effect.

[0059] In some embodiments, see Figure 4 As shown, Figure 4 : This is a structural schematic diagram of an LED display module provided in an exemplary embodiment of the present disclosure. The LED display module 2 also includes an LED control module 23. The LED display area 21 is connected to the LED fan-out area 22. The LED fan-out area 22 is connected to the LED control module 23. The LED control module 23 is configured to control the refresh direction of the LED display area 21. The LED display area 21 includes a plurality of light-emitting diode pixel areas arranged along the second direction Y, and each light-emitting diode pixel area includes a row of light-emitting diode pixels. After receiving the graphic information, the LED display module 2 controls the light-emitting diode pixel area to display the received graphic information row by row according to the refresh direction. The LED control module 23 includes a source driver chip 231, a gate driver chip 232 and a main control chip 233. The main control chip 233 is coupled to the source driver chip 231 and the gate driver chip 232 respectively. The source driver chip 231 (driver integrated circuit, driver IC) is used to control the brightness of the LED display area 21, and the gate driver chip 232 (gate integrated circuit, gate IC) is used to control the LED display area 21 to refresh row by row (i.e., row and column scanning). The main control chip 233 is used to receive graphic information and control the source driver chip 231 and the gate driver chip 232 to perform display driving.

[0060] In other embodiments, please refer to Figure 5 , Figure 5is a schematic structural diagram of another LED display module provided in an exemplary embodiment of the present disclosure, Figure 5 The embodiment shown and Figure 4 The difference between the shown embodiments is that Figure 5 The LED control module 23 includes two source driver chips 231, a gate driver chip 232 and a main control chip 233. By configuring two source driver chips 231, the brightness of the LED display area 21 with a large area and a large number of light-emitting diode pixels can be controlled. Since the number of light-emitting diode pixels that can be controlled by each source driver chip 231 is limited, and the number of light-emitting diode pixels that can be controlled by each gate driver chip 232 is limited, when the LED display area 21 includes fewer light-emitting diode pixels, each LED display area 21 can be configured with a source driver chip 231 and a gate driver chip 232. When the LED display area 21 includes more light-emitting diode pixels, each LED display area 21 can be configured with multiple source driver chips 231 and multiple gate driver chips 232. The number of source driver chips 231 and gate driver chips 232 can be set according to the number of light-emitting diode pixels, and this application does not limit this.

[0061] In some embodiments, the LED control module 23 is located outside the splicing area 12 and the LCD display area 11, which can prevent the LED control module 23 from blocking the LED display area 21 and the LCD display area 11 and improve the display effect.

[0062] In some embodiments, see Figure 6 As shown, Figure 6 : is a structural schematic diagram of a spliced ​​display screen provided in an exemplary embodiment of the present disclosure, wherein the LED display areas 21 of the two LED display modules 2 are configured to be refreshed in sequence along a first refresh direction. The two LED display modules 2 include a first module 3 and a second module 4. The first module 3 includes a first LED display area 31, a first LED fan-out area 32, and a first LED control module 33. The second module 4 includes a second LED display area 41, a second LED fan-out area 42, and a second LED control module 43. The first LED display area 31 is configured to be refreshed along a first refresh direction; the second LED display area 41 is configured to be refreshed along the first refresh direction after the first LED display area 31 finishes refreshing.

[0063] In some embodiments, one end of the first LED display area 31 away from the first LED fan-out area 32 abuts against one end of the second LED display area 41 away from the second LED fan-out area 42 .

[0064] In some embodiments, the left edge of the first LED display area 31 coincides with the left edge of the splicing area 12, the right edge of the first LED display area 31 coincides with the right edge of the splicing area 12, the upper edge of the first LED display area 31 coincides with the upper edge of the splicing area 12, the left edge of the second LED display area 41 coincides with the left edge of the splicing area 12, the right edge of the second LED display area 41 coincides with the right edge of the splicing area 12, and the lower edge of the second LED display area 41 coincides with the lower edge of the splicing area 12.

[0065] In some embodiments, see Figure 3 As shown, Figure 3 is a schematic structural diagram of a spliced ​​display screen provided in an exemplary embodiment of the present disclosure, Figure 3 The embodiment shown and Figure 1 The difference between the illustrated embodiments is that, when the length of the splicing area 12 along the second direction Y is small, the number of the LED display module 2 is 1. Part of the edge of the LED display area 21 of one LED display module 2 overlaps with the edge of the splicing area 12, and one LED display area 21 covers the splicing area 12. The LED fan-out area 22 of one LED display module 2 is located outside the splicing area 12 and the LCD display area 11.

[0066] Specifically, one LED fan-out area 22 may be disposed in the first edge area 131 .

[0067] Specifically, the left edge of the LED display area 21 coincides with the left edge of the splicing area 12 , the right edge of the LED display area 21 coincides with the right edge of the splicing area 12 , the upper edge of the LED display area 21 coincides with the upper edge of the splicing area 12 , and the lower edge of the LED display area 21 coincides with the lower edge of the splicing area 12 .

[0068] Based on the above embodiment, when the length of the splicing area 12 along the second direction Y is short, only one LED display module 2 is required to cover the splicing area 12 , thereby reducing the manufacturing cost of the splicing display screen.

[0069] In some embodiments, see Figure 7 As shown, Figure 7 is a schematic structural diagram of a spliced ​​display screen provided in an exemplary embodiment of the present disclosure, Figure 7 The embodiment shown and Figure 6 The difference between the illustrated embodiments is that the number of LED display modules 2 is 1. The LED display area 21 of one LED display module 2 is configured to be refreshed along the first refresh direction. Specifically, one LED display module 2 includes a third module 5, the third module 5 includes a third LED display area 51, a third LED fan-out area 52 and a third LED control module 53, and the third LED display area 51 is configured to be refreshed along the first refresh direction.

[0070] In some embodiments, see Figure 6 As shown, the LCD display area 11 is configured to be refreshed along a second refresh direction, and the second refresh direction is the same as the first refresh direction.

[0071] In some embodiments, see Figure 7 As shown, the LCD display area 11 is configured to be refreshed along a second refresh direction, and the second refresh direction is the same as the first refresh direction.

[0072] In some embodiments, the LCD display area 11 includes a plurality of liquid crystal pixel areas arranged along the second direction Y, and each liquid crystal pixel area includes a row of liquid crystal pixels. After receiving the graphic information, the LCD display module 1 controls the liquid crystal pixel area to display the received graphic information row by row according to the second refresh direction.

[0073] Based on the above embodiment, the LED display area 21 and the LCD display area 11 can be refreshed in the same direction.

[0074] Accordingly, the embodiment of the present application also proposes a control method for a spliced ​​display screen, wherein a playback control module (e.g., a front-end player) is provided outside the spliced ​​display screen, and the playback control module is used to send the first graphic information to the LED display module 2, and is also used to send the second graphic information to the LCD display module 1, see Figure 8 As shown, the method includes:

[0075] S101: After acquiring the first graphic information, the LED display area 21 refreshes the display content along the first refresh direction according to the first graphic information within the target refresh time period;

[0076] S102: After acquiring the second graphic information, the LCD display area 11 refreshes the display content along the second refresh direction according to the second graphic information within the target refresh time period.

[0077] The following is a detailed description with reference to the accompanying drawings.

[0078] Please refer to Figure 8 , execute step S101, after obtaining the first graphic information, the LED display area refreshes the display content along the first refresh direction according to the first graphic information within the target refresh time period.

[0079] In some embodiments, see Figure 6As shown, the number of LED display modules 2 is 2, the LED display module 2 includes a first module 3 and a second module 4, the first module 3 includes a first LED display area 31, the second module 4 includes a second LED display area 41, and the first graphic information includes third graphic information and fourth graphic information. The playback control module is used to send the third graphic information to the first module 3, and is also used to send the fourth graphic information to the second module 4. After acquiring the first graphic information, the LED display area 21 refreshes the display content along the first refresh direction according to the first graphic information within the target refresh time period, including:

[0080] After acquiring the third graphic information, the first LED display area 31 refreshes the display content along the first refresh direction according to the third graphic information within the first refresh time period;

[0081] After acquiring the fourth graphic information, the second LED display area 41 refreshes the display content along the first refresh direction according to the fourth graphic information within the second refresh time period; the sum of the first refresh time period and the second refresh time period is equal to the target refresh time period.

[0082] Specifically, the third graphic information and the fourth graphic information may be the same graphic information or different graphic information.

[0083] Specifically, the first LED display area 31 starts refreshing from an end close to the first LED fan-out area 32, and the second LED display area 41 starts refreshing from an end far from the second LED fan-out area 42. The moment when the first LED display area 31 ends refreshing is equal to the moment when the second LED display area 41 starts refreshing.

[0084] For example, the shapes of the first LED display area 31 and the second LED display area 41 are set to be the same, so the time length for the first LED display area 31 to complete the refresh is equal to the time length for the second LED display area 41 to complete the refresh, that is, the length of the first refresh time period is equal to the length of the second refresh time period. The starting time of the target refresh time is recorded as T0, the ending time of the target refresh time is recorded as T2, and the midpoint of T0 and T2 is recorded as T1, then the time from T0 to T1 is the first refresh time period, and the time from T1 to T2 is the second refresh time period.

[0085] At time T0, the play control module sends the second graphic information to the LCD display module 1, and sends the third graphic information to the first module 3. At time T1, the play control module sends the fourth graphic information to the second module 4.

[0086] In other embodiments, see Figure 7As shown, the number of LED display modules 2 is 1, and the LED display module 2 includes a third module 5, and the third module 5 includes a third LED display area 51. After the LED display area 21 obtains the first graphic information, it refreshes the display content along the first refresh direction according to the first graphic information within the target refresh time period, including: after the third LED display area 51 obtains the first graphic information, it refreshes the display content along the first refresh direction according to the first graphic information within the target refresh time period.

[0087] In some embodiments, at time T0 , the playback control module sends the second graphic information to the LCD display module 1 , and sends the first graphic information to the third module 5 .

[0088] Please continue to refer to Figure 8 , executing step S102: after acquiring the second graphic information, the LCD display area refreshes the display content along the second refresh direction according to the second graphic information within the target refresh time period.

[0089] In some embodiments, the second graphic information acquired by the two LCD display areas 11 may be the same graphic information or different graphic information.

[0090] Based on the above embodiment, the first LED display area 31, the second LED display area 41 and the LCD display area 11 can start refreshing and end refreshing at the same time, and the time when the first LED display area 31 ends refreshing is equal to the time when the second LED display area 41 starts refreshing, so the picture misalignment phenomenon can be eliminated, providing a better visual effect and improving the user's viewing experience. In addition, the third LED display area 51 and the LCD display area 11 can start refreshing and end refreshing at the same time, so the picture misalignment phenomenon can be eliminated, providing a better visual effect and improving the user's viewing experience.
