Detailed Description
The present invention provides a split type LED display panel and a control method thereof, and the present invention is further described in detail below in order to make the objects, technical solutions, and effects of the present invention clearer and clearer. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a split-type LED display panel according to an embodiment of the present invention, as shown in the figure, the split-type LED display panel includes a first transparent substrate 10, a second transparent substrate 20, and a third transparent substrate 30, which are arranged in parallel, blue, red, and green LEDs are uniformly arranged on the first transparent substrate 10 in sequence, red, green, and blue LEDs are uniformly arranged on the second transparent substrate 20 in sequence, green, blue, and red LEDs are uniformly arranged on the third transparent substrate 30 in sequence, among the first transparent substrate 10, the second transparent substrate 20, and the third transparent substrate 30, light shielding layers 40 are arranged at bottoms of the LEDs on the two transparent substrates arranged near a light-emitting side, and a size of the LED on the transparent substrate nearest to the light-emitting side is smaller than 100 um.
Preferably, in the present invention, the first transparent substrate, the second transparent substrate and the third transparent substrate may be arranged in parallel in any order, and the three transparent substrates are arranged from left to right in 6 arrangement manners, for example, the first transparent substrate, the third transparent substrate and the second transparent substrate are arranged from left to right in sequence; or the second transparent substrate, the third transparent substrate and the first transparent substrate are sequentially arranged from left to right; or the third transparent substrate, the second transparent substrate and the first transparent substrate are arranged from left to right in sequence.
In the embodiment shown in fig. 1, the three transparent substrates are specifically arranged from left to right in the following order: third transparent substrate 30, second transparent substrate 20 and first transparent substrate 10, then first transparent substrate 10 is for leaving the nearest transparent substrate in light-emitting side be provided with transparent protection apron 50 on the LED on the first transparent substrate 10, blue, red, the green LED that evenly sets up in proper order on the first transparent substrate 10 are the LED that the size is less than 100um, just LED bottom on first transparent substrate and the second transparent substrate all is provided with light shield layer 40.
In the display panel shown in fig. 1, light emitted by the LEDs in the second transparent substrate and the third transparent substrate is divided into two parts, one part is absorbed by the light shielding layer, and the other part is emitted through the transparent substrate and the transparent protective cover plate to realize a display function; the light emitted by the LED on the first transparent substrate is totally emitted out through the transparent protective cover plate. In order to realize the display effect at the Micro-LED level, the size of the LED on the first transparent substrate is less than 100um, the size of the LED on the second transparent substrate is less than 200um, the distance between the adjacent LEDs on the second transparent substrate is less than 100um, the size of the LED on the third transparent substrate is less than 300um, and the size of the shading layer is less than or equal to that of the LED. The pixel size of the LED display is below 100um, and the Micro-LED display effect is achieved.
Preferably, the transparent protective cover plate is used for protecting the LEDs on the first transparent substrate from abrasion and damage.
The split type LED display panel provided by the embodiment eliminates the non-display interval between the pixels, thereby eliminating the granular sensation during the picture display and greatly improving the display effect.
Preferably, the material of the light shielding layer is one of a resin or an ink, but is not limited thereto. The light shielding layer is mainly used for shielding light emitted by the LED right behind the light shielding layer and preventing color mixing, and the light shielding layer is manufactured in one of printing, exposure etching, embossing and the like, but is not limited thereto.
Preferably, the material of the first transparent substrate, the second transparent substrate and the third transparent substrate is independently selected from one of glass or polyimide, but not limited thereto. More preferably, the first transparent substrate, the second transparent substrate and the third transparent substrate are made of polyimide, and the transmittance of the transparent substrate made of the polyimide can reach over 90%.
In a preferred embodiment, as shown in fig. 1, supports 60 are disposed between the first transparent substrate 10, the second transparent substrate 20, the third transparent substrate 30 and the transparent protective cover 50, and the supports are disposed to prevent collision between adjacent transparent substrates and also to perform an assembling function.
The split type LED display panel provided by the invention can switch different display modes by sending different control signals so as to be suitable for different application scenes.
Specifically, the control method of the split LED display panel provided by the present invention, as shown in fig. 2, includes the steps of:
s10, when the split type LED display panel is used for large-viewing-angle display, sending the same control signal to LEDs with the same color in one pixel, wherein the one pixel comprises at least two red LEDs, at least two green LEDs and at least two blue LEDs;
s20, when the split type LED display panel is used for small-view display, different control signals are sent to LEDs with different colors in one pixel, and the one pixel comprises one red LED, one green LED and one blue LED.
In a preferred embodiment, as shown in fig. 3, when the split LED display panel is used for a small viewing angle display, for example, only for a front viewing angle, different control signals are sent to LEDs of different colors in a pixel, where a pixel includes only one red LED, one green LED and one blue LED. In this embodiment, since the size of a single pixel is the smallest, the PPI of the display panel is effectively improved, so that the display panel in this embodiment has an optimized front view display effect, and a fine picture without granular sensation; but the visual angle is small, and the method is only suitable for application scenes such as AR, VR, mobile phones and desktop displays which have low requirements on the size of the viewing angle, and the application scenes do not need to share the display content by a plurality of people.
In a preferred embodiment, as shown in fig. 4 and 5, when the split LED display panel is used for a large viewing angle display, the same control signal is sent to the same color LEDs in one pixel, and the one pixel includes two red LEDs, two green LEDs, and two blue LEDs. At this time, the size of a single pixel becomes large, and the front view display effect thereof becomes poor compared to that of the display panel of fig. 3, but since the LED display panel in this embodiment also realizes the Micro-LED level display, the volume display effect is still better than that of the LED display panel in the current market. Further, since the LEDs with the same color in a single pixel in this embodiment can obtain the same control signal, when the side view angle is large, the LEDs with two different colors on the first transparent substrate and the third color LED on the second transparent substrate form a complete display pixel, so that the problem of narrow view angle of the existing LED display panel can be improved to a certain extent.
Preferably, in this embodiment, since a part of light of the LED pixels on the second transparent substrate is absorbed by the first transparent substrate, in order to improve the display brightness and color uniformity of the LED display panel, the driving current of the second transparent substrate can be increased, so as to improve the large-viewing-angle display effect of the LED display panel.
In a preferred embodiment, as shown in fig. 6 and 7, when the split LED display panel is used for a large viewing angle display, the same control signal is sent to the same color LED in one pixel, and the one pixel may further include three red LEDs, three green LEDs, and three blue LEDs. In this embodiment, the size of a single pixel becomes larger, and the front view display effect of the single pixel becomes worse relative to the front view display effect of the display panel of fig. 5. However, when the display panel in this embodiment is viewed from a side view, the display effect at a large viewing angle is the best because the first transparent substrate and the second transparent basic LEDs provide effective three-color display pixels.
Preferably, if the LED display panel provided in this embodiment is only used for large-viewing-angle display, the control signal of the third transparent substrate may be turned off, because the third transparent substrate is not used in the large-viewing-angle display, the power consumption of the LED display panel of the present invention may be effectively reduced.
Specifically, the LED display panel provided by the present invention can switch the required modes according to the actual application scenarios, for example, in AR or VR application scenarios, the most perfect display effect can be obtained through the small viewing angle control mode of fig. 3 without suffering from the viewing angle; in an application scenario of an auditorium or a conference room, the display effect of a large viewing angle can be improved by the large viewing angle control mode of fig. 4 or fig. 7, and although the fineness of the picture is reduced, the display effect is still higher than that of the LED display panel in the current market.
In summary, the split-type LED display panel provided by the present invention can realize Micro-LED level display without fully using a small-sized (less than 100 um) LED, and can also switch different display modes according to different application scenes, especially can be used for a large viewing angle display scene, and can effectively solve the problem of a small viewing angle of the existing LED display panel.
It is to be understood that the invention is not limited to the examples described above, but that modifications and variations may be effected thereto by those of ordinary skill in the art in light of the foregoing description, and that all such modifications and variations are intended to be within the scope of the invention as defined by the appended claims.
