Description

Technical Field

[0002] In recent years, displays have played an important role in various electronic products to provide high-quality images to users. Since transparent displays can be naturally integrated into the user's environment, they are becoming more and more popular.

[0003] Generally speaking, the higher the transmittance of a transparent display, the clearer the see-through effect of the transparent display. The transmittance of a transparent display depends on the area outside the light-emitting element and its circuit (also known as the aperture ratio). In order to increase the aperture ratio, transparent displays use a field sequential color (FSC) driving method to reduce the circuit area. However, conventional field sequential color displays have a color breakup (CBU) problem that affects the visual effect. Summary of the invention

The embodiments of the components and configurations described below are merely examples and are not intended to be limiting. In addition, for the purpose of simplicity and clarity, the present invention repeats reference symbols and / or numbers in each example, which in itself does not limit the relationship between the various embodiments and / or components discussed.

[0054] The terms “first,” “second,” etc. used in this document do not particularly refer to an order or sequence, but are only used to distinguish elements or operations described with the same technical terminology.

[0055] Please refer to Figure 1 , Figure 1 FIG. 2 is a schematic diagram showing the arrangement of pixel blocks of a display device according to an embodiment of the present invention. Figure 1As shown, in an embodiment of the present invention, the display device includes a plurality of pixel blocks PX, and these pixel blocks PX are arranged in a matrix manner. For example, these pixel blocks PX are arranged into a plurality of pixel columns 110 and a plurality of pixel rows 120. Each pixel block PX includes a first color sub-pixel block R, a second color sub-pixel block G, and a third color sub-pixel block B. The first color sub-pixel block R, the second color sub-pixel block G, and the third color sub-pixel block B are used to emit light of different colors. In the present embodiment, the first color sub-pixel block R corresponds to a first color (e.g., red); the second color sub-pixel block G corresponds to a second color (e.g., green); and the third color sub-pixel block B corresponds to a third color (e.g., blue). However, the embodiments of the present invention are not limited thereto.

[0056] Please refer to FIG. 2A to FIG. 2C , Figure 2A is a diagram illustrating a color sequence of a first sub-frame and a second sub-frame according to an embodiment of the present invention; Figure 2B and 2C 1 is a diagram illustrating the light emitting operation of the pixel blocks PX1-PX4 when the first sub-frame and the second sub-frame are displayed according to an embodiment of the present invention. For the convenience of explanation, the embodiment of the present invention is illustrated by taking the pixel blocks PX1-PX4 of two adjacent n-th pixel columns and n+1-th pixel columns as examples, wherein the pixel blocks PX1-PX4 are adjacent pixel blocks to each other, and n is a positive integer.

[0057] like Figure 2A As shown, in the present embodiment, the frame of the display device is divided into a first sub-frame and a second sub-frame. When the first sub-frame is displayed, the first sub-pixel block and the second sub-pixel block are controlled to emit light to present two different colors, such as red and green. When the second sub-frame is displayed, the first sub-pixel block and the third sub-pixel block are controlled to emit light to present two different colors, such as red and blue. Specifically, in the present embodiment, the first sub-frame displays a first color (e.g., red) and a second color (e.g., green), while the second sub-frame displays the same first color as the first sub-frame and a third color (e.g., blue) different from the first sub-frame. In this way, the display device of the present embodiment can use the above-mentioned color sequence to achieve the purpose of color display.

[0058] like Figure 2BAs shown, when the first sub-frame is displayed, the first color sub-pixel block R and the second color sub-pixel block G of the pixel blocks PX1 and PX2 of the nth pixel column emit light to display the first color and the second color, while the third color sub-pixel block B does not emit light; the first color sub-pixel block R and the second color sub-pixel block G of the pixel blocks PX3 and PX4 of the n+1th pixel column emit light to display the first color and the second color, while the third color sub-pixel block B does not emit light.

[0059] like Figure 2C As shown, when the second sub-frame is displayed, the first color sub-pixel block R and the second color sub-pixel block B of the pixel blocks PX1 and PX3 of the nth pixel column emit light to display the first color and the third color, while the second color sub-pixel block G does not emit light; the first color sub-pixel block R and the third color sub-pixel block B of the pixel blocks PX3 and PX4 of the n+1th pixel column emit light to display the first color and the third color, while the second color sub-pixel block G does not emit light.

[0060] According to the above Figure 2A-2C , Figure 2A-2C The color sequence of the embodiment may be, for example, red / green-red / blue, so that the purpose of color display can be achieved.

[0061] Please refer to FIG. 3A to FIG. 3C , Figure 3A is a diagram illustrating a color sequence of a first sub-frame and a second sub-frame according to an embodiment of the present invention; Figure 3B and 3C FIG. 1 illustrates the light emitting operation of the pixel blocks PX1 - PX4 when the first sub-frame and the second sub-frame are displayed according to an embodiment of the present invention.

[0062] like Figure 3A As shown, similar to the above-mentioned embodiment, the frame of the display device is divided into a first sub-frame and a second sub-frame. When the first sub-frame is displayed, the first sub-pixel block, the second sub-pixel block and the third sub-pixel block are controlled to emit light to present three different colors, such as red, green and blue. Similarly, when the third sub-frame is displayed, the first sub-pixel block, the second sub-pixel block and the third sub-pixel block are also controlled to emit light to present three different colors, such as red, green and blue. Specifically, in the present embodiment, the first sub-frame and the second sub-frame both display a first color (e.g., red), a second color (e.g., green) and a third color (e.g., blue).

[0063] like Figure 3BAs shown, when the first sub-frame is displayed, the first color sub-pixel block R and the third color sub-pixel block B of the pixel block PX1 of the nth pixel column emit light to display the first color and the third color, the second color sub-pixel block G of the pixel block PX2 emits light to display the second color, and the second color sub-pixel block G of the pixel block PX1 and the first color sub-pixel block R and the third color sub-pixel block B of the pixel block PX2 do not emit light; the second color sub-pixel block G of the pixel block PX3 of the n+1th pixel column emits light to display the second color, the first color sub-pixel block R and the third color sub-pixel block B of the pixel block PX4 emit light to display the first color and the third color, while the first color sub-pixel block R and the third color sub-pixel block B of the pixel block PX3 and the second color sub-pixel block G of the pixel block PX4 do not emit light.

[0064] like Figure 3C As shown, when the second sub-frame is displayed, the second color sub-pixel block G of the pixel block PX1 of the nth pixel column emits light to display the second color, the first color sub-pixel block R and the third color sub-pixel block B of the pixel block PX2 emit light to display the first color and the third color, while the first color sub-pixel block R and the third color sub-pixel block B of the pixel block PX1 and the second color sub-pixel block G of the pixel block PX2 do not emit light; the first color sub-pixel block R and the third color sub-pixel block B of the pixel block PX3 of the n+1th pixel column emit light to display the first color and the third color, the second color sub-pixel block G of the pixel block PX4 emits light to display the second color, while the second color sub-pixel block G of the pixel block PX3 and the first color sub-pixel block R and the third color sub-pixel block B of the pixel block PX4 do not emit light.

[0065] According to the above Figure 3A-3C, the pixel block PX1 displays the first color and the third color during the time period displayed in the first sub-frame, and displays the second color during the time period displayed in the second sub-frame, so that the color sequence of the pixel block PX1 when the entire frame is displayed can be, for example, red / blue-green, so that the pixel block PX1 achieves the purpose of color display. The pixel block PX2 displays the second color during the time period displayed in the first sub-frame, and displays the first color and the third color during the time period displayed in the second sub-frame, so that the color sequence of the pixel block PX2 when the entire frame is displayed can be, for example, green-red / blue, so that the pixel block PX2 achieves the purpose of color display. The pixel block PX3 displays the second color during the time period displayed in the first sub-frame, and displays the first color and the third color during the time period displayed in the second sub-frame, so that the color sequence of the pixel block PX3 when the entire frame is displayed can be, for example, green-red / blue, so that the pixel block PX3 achieves the purpose of color display. Pixel block PX4 displays the first color and the third color during the period of the first sub-frame display, and displays the second color during the period of the second sub-frame display. In this way, the color sequence of pixel block PX4 when displaying the entire frame can be, for example, red / blue-green, so that pixel block PX4 achieves the purpose of color display.

[0066] In addition, during the display period of the first sub-frame and the second sub-frame, the pixel blocks of each pixel column are operated in a display mode of, for example, green-red / blue-green-red / blue, and the pixel blocks of each pixel row are also operated in a display mode of green-red / blue-green-red / blue. The above-mentioned staggered display mode can make the color display effect of the display device of the present invention more uniform.

[0067] Please refer to FIG. 4A to FIG. 4C , Figure 4A is a diagram illustrating a color sequence of a first sub-frame and a second sub-frame according to an embodiment of the present invention; Figure 4B and 4C FIG. 1 illustrates the light emitting operation of the pixel blocks PX1 - PX4 when the first sub-frame and the second sub-frame are displayed according to an embodiment of the present invention.

[0068] like Figure 4A As shown, similar to the above-mentioned embodiment, the frame of the display device is divided into a first sub-frame and a second sub-frame. When the first sub-frame is displayed, the first sub-pixel block, the second sub-pixel block and the third sub-pixel block are controlled to emit light to present three different colors, such as red, green and blue. Similarly, when the third sub-frame is displayed, the first sub-pixel block, the second sub-pixel block and the third sub-pixel block are also controlled to emit light to present three different colors, such as red, green and blue. Specifically, in the present embodiment, the first sub-frame and the second sub-frame both display a first color (e.g., red), a second color (e.g., green) and a third color (e.g., blue).

[0069] like Figure 4B As shown, when the first sub-frame is displayed, the first color sub-pixel block R and the second color sub-pixel block G of the pixel block PX1 of the nth pixel column emit light to display the first color and the second color, the first color sub-pixel block R and the third color sub-pixel block B of the pixel block PX2 emit light to display the first color and the third color, while the third color sub-pixel block B of the pixel block PX1 and the second color sub-pixel block G of the pixel block PX2 do not emit light; the first color sub-pixel block R and the third color sub-pixel block B of the pixel block PX3 of the n+1th pixel column emit light to display the first color and the third color, the first color sub-pixel block R and the second color sub-pixel block G of the pixel block PX4 emit light to display the first color and the second color, while the second color sub-pixel block G of the pixel block PX3 and the third color sub-pixel block B of the pixel block PX4 do not emit light.

[0070] like Figure 4C As shown, when the second sub-frame is displayed, the first color sub-pixel block R and the third color sub-pixel block B of the pixel block PX1 of the nth pixel column emit light to display the first color and the third color, the first color sub-pixel block R and the second color sub-pixel block G of the pixel block PX2 emit light to display the first color and the second color, while the second color sub-pixel block G of the pixel block PX1 and the third color sub-pixel block B of the pixel block PX2 do not emit light; the first color sub-pixel block R and the second color sub-pixel block G of the pixel block PX3 of the n+1th pixel column emit light to display the first color and the second color, the first color sub-pixel block R and the third color sub-pixel block B of the pixel block PX4 emit light to display the first color and the third color, while the third color sub-pixel block B of the pixel block PX3 and the second color sub-pixel block G of the pixel block PX4 do not emit light.

[0071] According to the above Figures 4A-4C, the pixel block PX1 displays the first color and the second color in the time period displayed by the first sub-frame, and displays the first color and the third color in the time period displayed by the second sub-frame, so that the color sequence of the pixel block PX1 when the entire frame is displayed can be, for example, red / green-red / blue, so that the pixel block PX1 achieves the purpose of color display. The pixel block PX2 displays the first color and the third color in the time period displayed by the first sub-frame, and displays the first color and the second color in the time period displayed by the second sub-frame, so that the color sequence of the pixel block PX2 when the entire frame is displayed can be, for example, red / blue-red / green, so that the pixel block PX2 achieves the purpose of color display. The pixel block PX3 displays the first color and the third color in the time period displayed by the first sub-frame, and displays the first color and the second color in the time period displayed by the second sub-frame, so that the color sequence of the pixel block PX2 when the entire frame is displayed can be, for example, red / blue-red / green, so that the pixel block PX3 achieves the purpose of color display. Pixel block PX4 displays the first color and the second color during the period of displaying the first sub-frame, and displays the first color and the third color during the period of displaying the second sub-frame. In this way, the color sequence of pixel block PX4 when displaying the entire frame can be, for example, red / green-red / blue, so that pixel block PX1 achieves the purpose of color display.

[0072] In addition, during the display period of the first sub-frame and the second sub-frame, the pixel blocks of each pixel column are operated in a display mode of, for example, red / green-red / blue-red / green-red / blue, and the pixel blocks of each pixel row are also operated in a display mode of red / green-red / blue-red / green-red / blue. The above-mentioned staggered display mode can make the color display effect of the display device of the present invention more uniform.

[0073] Please refer to Figure 5A and Figure 5B , which is a flow chart of control methods 500A and 500B of a display device according to the above embodiment of the present invention. Figure 5A As shown, in the control method 500A, step 510 is performed to provide a first pixel column (eg, the nth pixel column mentioned above). Then, step 520 is performed to divide the frame into a first sub-frame and a second sub-frame, as described above. Figure 2A , Figure 3A , Figure 4A Next, step 530 is performed to define M first mixed color pixel blocks and N first monochrome pixel blocks. The first mixed color pixel blocks are pixel blocks for dual color display (e.g. Figure 2B The pixel block PX1 shown in the figure is a pixel block for monochrome display (for example, Figure 3B In the embodiment of the present invention, M is an integer greater than 1, and N is an integer greater than or equal to 0.

[0074] Specifically, when N=0, step 540 is performed to control the first color sub-pixel block and the second color sub-pixel block of at least one of the first mixed color pixel blocks to emit light in the first sub-frame, and to control the first color sub-pixel block and the third color sub-pixel block of at least one of the first mixed color pixel blocks to emit light in the second sub-frame. Figure 2B and Figure 2C As shown, the first color sub-pixel block and the second color sub-pixel block of the pixel block PX1 emit light in the first sub-frame, and the first color sub-pixel block and the third color sub-pixel block of the pixel block PX1 emit light in the second sub-frame. Figure 4B and Figure 4C As shown, the first color sub-pixel block and the second color sub-pixel block of the pixel block PX1 emit light in the first sub-frame, and the first color sub-pixel block and the third color sub-pixel block of the pixel block PX1 emit light in the second sub-frame.

[0075] When N≠0, step 550 is performed to control the first color sub-pixel block and the third color sub-pixel block of each first mixed color pixel block to emit light in the first sub-frame, and control the second color sub-pixel block of each first monochrome pixel block to emit light in the first sub-frame. Figure 3B As shown, the first color sub-pixel block and the third color sub-pixel block of the pixel block PX1 emit light in the first sub-frame, and the second color sub-pixel block of the pixel block PX2 also emits light in the first sub-frame. It is worth noting that the designation of monochrome and mixed color pixel blocks can be changed. For example, in the first sub-frame, the pixel blocks PX1 and PX4 are designated as mixed color pixel blocks, while in the second sub-frame, the pixel blocks PX1 and PX4 are designated as monochrome pixel blocks. Similarly, in the first sub-frame, the pixel blocks PX2 and PX3 are designated as monochrome pixel blocks, while in the second sub-frame, the pixel blocks PX2 and PX3 are designated as mixed color pixel blocks.

[0076] like Figure 5B As shown, in the control method 500B, step 560 is performed to provide a second pixel row (e.g., the n+1th pixel row mentioned above). Then, step 570 is performed to define X second mixed color pixel blocks and Y second monochrome pixel blocks.
