Description

Display device and pixel unit

The present invention relates to a display device and a pixel unit, and more particularly to a transparent display device and a pixel unit that can control transparency.

Transparent display devices have been actively developed in recent years. Unlike traditional displays, viewers can view the pictures displayed on the transparent display devices, and at the same time, they can see the objects behind the transparent display devices, which can be widely used in applications. Such as conference room compartments, display windows, advertising screens, head-up displays, etc., even the current 3C product display screens can be used.

However, the authenticity of the screen display presented by the transparent display device is slightly poor. In order to achieve good penetration, the power consumption of the display device itself and the user's acceptability must be taken into account. Therefore, there are still many transparent display devices. Improve space.

The object of the present invention is to provide a display device and a pixel unit, which can not only display transparently, but also control the transparency, or control the degree of transparency occurring in different regions. In addition to making the display effect better, the display style can be more diverse and rich. And the structure of the display device will not be too complicated, which is conducive to production and commercialization.

The present invention relates to a display device and a pixel unit, including an organic light emitting diode display module and a micro light emitting diode display module.

The organic light emitting diode display module includes a plurality of organic light emitting diodes for displaying text or image images. Among these organic light emitting diodes, there is a perspective region between two adjacent organic light emitting diodes. The micro-light emitting diode display module includes a plurality of micro-light emitting diodes, and at least one of the micro-light emitting diodes is disposed in a perspective region.

In addition, the present invention also relates to a display device including a plurality of pixel units, each of which includes a display area and a perspective area, an organic light emitting diode is arranged in the display area, and at least one micro light emitting diode is arranged in the perspective area. body.

In summary, the perspective area of the display device of the present invention has different transparency under different operating states. For example, the transparency includes at least a first transparency or a second transparency. When the microluminescent diode emits light, the microluminescent diode The perspective area where the polar body is located has a first transparency. When the micro-light-emitting diode does not emit light, this perspective area will have a second transparency, and the first transparency will be smaller than the second transparency.

Further, the display device can control the light-emitting intensity of the micro-light-emitting diodes by controlling the operating voltage of the light-emitting diodes.

It is added that the organic light emitting diodes and the micro light emitting diodes are preferably arranged in an array, or it can be said that the plurality of pixel units are preferably arranged in an array. The organic light emitting diode is preferably an active organic light emitting diode, and the micro light emitting diode may be an active or passive micro light emitting diode.

As in the aforementioned display device, three micro-light-emitting diodes can be set in the perspective region, and the three micro-light-emitting diodes are respectively a red micro-light-emitting diode, a green micro-light-emitting diode, and a blue Microluminescent diode. Therefore, the micro-light-emitting diode can not only control the transparency, but also present these transparency states in multiple styles or colors.

To further explain, the purpose of the display device is to display an image of text or image, and this image is displayed by an organic light emitting diode, so the display device needs to generate an image of text or image In the area, turning off the micro-light-emitting diode can have a transparent effect, and turning on the micro-light-emitting diode can have an opaque effect. If in the area where the display device does not need to generate images such as text or images, the micro-luminescent diode can be directly turned off to have a transparent effect. If it is to be opaque, not only the micro-luminescent diode is turned on to generate corresponding transparency. , And it is better to adjust the light emitting degree of the organic light emitting diode in this area so that the display area of this area has the same transparency as the perspective area.

Therefore, with the display device and the pixel unit capable of changing the transparent state provided by the present invention, the arrangement of the organic light-emitting diode display module not only enables the display device to display transparently, but also uses a micro-light-emitting diode display module. Setting to change the transparency, or control different areas to form different transparency, which not only makes the display effect better, but also makes the display style more diverse, and can simplify the structure of the display device, which is beneficial to production and commercialization.

Please refer to FIG. 1. FIG. 1 is a schematic diagram showing the position of a perspective region in a display device of the present invention. The present invention is a display device 20, which can not only see images of characters or graphics displayed by the display device 20, but also see through the scene behind the display device 20, and can also change the transparency into a variety of display modes. The display device 20 shown in FIG. 1 includes an organic light emitting diode display module 30 and a micro light emitting diode display module 32. The organic light emitting diode display module 30 includes a plurality of organic light emitting diodes (OLEDs). 3002, the micro-light-emitting diode display module 32 includes a plurality of micro-light-emitting diodes (μLED) 3202. The plurality of organic light-emitting diodes 3002 and the plurality of micro-light-emitting diodes can be arranged in an array. In the same column, the organic light emitting diode (OLED) 3002 of the organic light emitting diode display module 30 and the micro light emitting diode (μLED) 3202 of the micro light emitting diode display module 32 are alternately disposed.

The organic light emitting diode display module 30 includes a plurality of organic light emitting diodes (OLEDs) 3002. Among these organic light emitting diodes 3002, there is a perspective region 3210 between two adjacent organic light emitting diodes 3002. The distance between two organic light emitting diodes 3002 is about several The width of the organic light-emitting diode 3002, in this embodiment, is, for example, the width of two or three organic light-emitting diodes 3002, and this distance space constitutes the aforementioned perspective region 3210. Through the perspective region 3210, the display can be seen through The device 20 allows a person located on the front of the display device 20 to see through the objects on the back.

In order to save power or facilitate large-area display applications, the organic light emitting diode 3002 is preferably an active organic light emitting diode 3002. In the illustration, these organic light emitting diodes 3002 are arranged in an array. On both sides of the display device 20 are source driving circuits, such as a source driver IC 22 and a gate driving circuit such as a gate driver IC 24. The array is arranged in an array. The organic light emitting diode 3002 is respectively connected to the source driving chip group 22 and the gate driving chip group 24 to be driven and lighted. In this embodiment, the organic light emitting diode 3002 is used to present an image or text of the display device 20 Wait until the image is displayed.

Further, the organic light emitting diodes 3002 arranged in an array include a red organic light emitting diode 3020, a green organic light emitting diode 3022, and a blue organic light emitting diode 3024, which are sequentially arranged, but are not limited thereto. In other embodiments, the organic light-emitting diodes 3002 arranged in an array include at least the aforementioned red organic light-emitting diode 3020, green organic light-emitting diode 3022, and blue organic light-emitting diode 3024. Ordered and / or distributed.

The micro-light-emitting diode display module 32 includes a plurality of micro-light-emitting diodes (μLEDs) 3202. At least one of the micro-light-emitting diodes 3202 is disposed in the see-through region 3210. For example, the microluminescent diode 3202 of this embodiment is formed by, for example, a wafer having a thickness of about 4 μm to 5 μm, and the epitaxial layer is peeled off and then transplanted onto a circuit substrate by a physical or chemical mechanism, and the size is between 1 μm and 15 μm Meanwhile, the preferred size in this embodiment is 1 μm to 10 μm, which is different from a general light-emitting diode (LED) in that a general light-emitting diode (LED) wafer includes a substrate and an epitaxial layer, and its thickness is about 100 μm. ~ 500μm, and the size is between 100μm ~ 1000μm, so the micro-light-emitting diode (μLED) 3202 referred to in this embodiment does not affect the perspective area because of its small size The transparency of 3210, that is, although the micro-light emitting diode (μLED) 3202 will still occupy a part of the penetration area of the perspective area, the transparency of the perspective area 3210 can still be maintained.

The micro-luminescent diode 3202 can be an active or passive micro-luminescent diode 3202. When the display device 20 adopts the passive micro-emitting diode 3202, the display device 20 with higher transparency and resolution can be obtained. Preferably, the micro-luminescent diode 3202 can be an inorganic-micro-luminescent diode. In other embodiments, the organic light-emitting diode 3202 may be used as the light-emitting diode.

These micro light emitting diodes 3202 are arranged in an array, and the micro light emitting diodes 3202 arranged in an array are respectively connected to the source driving chip group 22 and the gate driving chip group 24 to be driven and lighted.

The perspective region 3210 has corresponding transparency. The transparency of the perspective region 3210 includes at least a first transparency or a second transparency under different operating states. When the micro-light emitting diode 3202 is driven to light and emit light, the perspective region 3210 has a first transparency. Transparency, and controlling the light-emitting degree of the micro-light-emitting diode 3202 can further control the level of the first transparency. When the micro-light-emitting diode 3202 is not driven to light and does not emit light, the see-through region 3210 has a second transparency. One transparency is less than the second transparency. Therefore, by controlling the transparency, the see-through region 3210 can be changed in transparency, so that the entire display device 20 can generate multiple transparent presentation modes.

In a preferred situation, at least three micro-light-emitting diodes 3202 can be provided in the perspective region 3210. The three micro-light-emitting diodes 3202 are red micro-light-emitting diodes 3220, green micro-light-emitting diodes 3222, and The blue micro-light emitting diode 3224 can generate richer transparency changes, which can not only change the degree of perspective of the display device 20, but also generate transparency changes of different colors.

To further explain, the purpose of the display device 20 is to display images of text or images. The images such as text or images are displayed by the organic light emitting diode 3002. Therefore, in this embodiment, the display device 20 displays text or images. In areas such as images, you can turn off the micro-luminescent diode 3202. There is a transparent effect, and the opaque effect can be obtained by turning on the micro-luminescent diode 3202. If the light emitting diode 3202 is directly turned off in an area where the display device 20 does not display images such as text or images, a transparent effect can be achieved. If an opaque effect is required, not only the micro light emitting diode 3202 is turned on to generate Corresponding transparency, and it is best to adjust the light emitting degree of the organic light emitting diode 3002 in this area so that this area has consistent transparency, that is, when the see-through area 3210 in this area is the first transparency, the organic light emitting diode The transparency of the image area such as text or image displayed by the body 3002 should be substantially equal to the first transparency. If the perspective area 3210 in this area is the second transparency, the transparency of the image area of the organic light emitting diode 3002 is also It is substantially consistent with the second transparency.

Please refer to FIG. 2, which is a schematic diagram of a pixel unit structure in a display device of the present invention. The display device 20 of this embodiment is described using the pixel unit 10 as an example.

As shown in the figure, the embodiment includes a plurality of organic light-emitting diodes 3002 and a plurality of micro-light-emitting diodes 3202 arranged in an array, wherein the organic light-emitting diodes 3002 and the micro-light-emitting diodes 3202 are mutually arranged in each column. The pixel units 10 are arranged alternately, and the pixel unit 10 includes at least one organic light-emitting diode 3002 and at least one micro-light-emitting diode 3202 adjacent thereto. In other words, the pixel unit 10 of this embodiment includes at least one organic light-emitting diode 3002. And at least one micro-light emitting diode 3202 is defined, so that the entire light-emitting area of the display device 20 has a plurality of pixel units 10, and each pixel unit 10 further defines at least one display area 3010 And a see-through region 3210, the display region 3010 is provided with an organic light emitting diode 3002, and the see-through region 3210 is provided with at least one micro-light emitting diode 3202. The see-through region 3210 is also a gap between two adjacent organic light emitting diodes 3002. The distance of this gap is about the width of several organic light emitting diodes 3002. In this embodiment, for example, two or three The width of the organic light emitting diode 3002, and this distance space constitutes the aforementioned see-through region 3210. Through the see-through region 3210, the display device 20 can be seen through, so that a person on the front side of the display device 20 can see through the back object.

Wherein, the plurality of pixel units 10 are preferably arranged in an array as shown in the figure, which will cause the organic light emitting diodes 3002 to be arranged in an array and the micro light emitting diodes 3202 to be arranged in an array. The organic light emitting diode 3002 and the micro light emitting diode 3202 are respectively driven by the source driving chip group 22 and the gate driving chip group 24 on both sides of the display device 20 and are turned on. In this embodiment, the organic light-emitting diode 3002 is used to display an image display such as an image or a text of the display device 20. The light-emitting diode 3202 can be illuminated with different transparency according to different lighting levels.

Similarly, the organic light emitting diode 3002 is preferably an active organic light emitting diode 3002. The micro-emitting diode 3202 can be an active or passive micro-emitting diode 3202. When the transparency presented by the display device 20 is insufficient, or when a more transparent display device 20 needs to be designed and the resolution needs to be improved, Because the active micro-light-emitting diode 3202 has thin-film transistors and capacitors and other components, it will occupy space and reduce the perspective area 3210. Therefore, a passive micro-light-emitting diode 3202 may be used. When the display device 20 has sufficient transparency, The active micro-emitting diode 3202 can maintain the transparency and resolution of the display device 20.

The organic light emitting diodes 3002 arranged in an array, for example, include at least a red organic light emitting diode 3020, a green organic light emitting diode 3022, and a blue organic light emitting diode 3024 in order. 20 Display diversity contains multiple color text or graphic images. At least three micro-light-emitting diodes 3202 can be set in the perspective region 3210. The three micro-light-emitting diodes 3202 are red micro-light-emitting diodes 3220, green micro-light-emitting diodes 3222, and blue micro-light-emitting diodes, respectively. The body 3224 can generate richer changes in transparency in this way. In addition to changing the perspective of the display device 20, it can also display the transparency of different colors.

Wherein, when the microluminescent diode 3202 emits light, the perspective region 3210 where the microluminescent diode 3202 is located has a first transparency. When the microluminescent diode 3202 does not emit light, the perspective region 3210 where the microluminescent diode 3202 is located has a second transparency, and the first transparency is smaller than the first transparency. Second transparency. Therefore, by controlling the transparency, the display device 20 can be changed in transparency, and various transparency presentation modes can be generated.

To further explain, the text or image is displayed by the organic light emitting diode 3002, so in the area where the display device 20 needs to generate text or image, turning off the micro light emitting diode 3202 can have a transparent effect and turn on the micro light emitting. Diode 3202 can have an opaque effect. If in the area where the display device 20 does not need to generate text or images, the micro-light-emitting diode 3202 can be directly turned off to have a transparent effect. If the opaque effect is required, not only the micro-light-emitting diode 3202 is turned on to generate a corresponding effect. Transparency, and it is better to adjust the light emitting degree of the organic light emitting diode 3002 in this area, so that the display area 3010 of this area has substantially the same transparency as the see-through area 3210. If the organic light emitting diode 3002 has a third transparency when it emits light, the third transparency is substantially the same as the first transparency, that is, if the see-through region 3210 in this area is the first transparency, the organic light emitting diode 3002 is also the same. For the first transparency, if the see-through region 3210 in this region is the second transparency, the organic light emitting diode 3002 is also uniformly the second transparency.

Please refer to FIG. 3. The microluminescent diode 3202 of the present invention is, for example, a vertical microluminescent diode 3202.

The anode of the electrode body 3002 is electrically connected to the anode line 42b, and a current is supplied to the organic light emitting diode 3002 through the cathode line 40 and the anode line 42b. In the same pixel unit 10, a vertical light emitting diode 3202 is provided with a conductor portion 42c electrically connected to the cathode, and the conductor portion 42c is electrically connected to a common cathode line 40, and the micro light emitting diode 3202 The anode is electrically connected to the anode line 42a, and the cathode line 40 and the anode line 42a supply a current to the microluminescent diode 3202.

The display device 20 can control the operating voltage or current of the microluminescent diode 3202 through the cathode circuit 40 and the anode circuit 42a of the microluminescent diode 3202 in each pixel unit 10, thereby controlling the microluminescent diode 3202. The luminous intensity of 3202, which is to control the micro-luminescent diode 3202 The luminous flux, which in turn produces the aforementioned transparency. If the operating voltage of the micro-emitting diode 3202 is adjusted so that the micro-emitting diode 3202 is kept at a low gray level or is not lit, the transparency of the display device 20 may be increased. If the operating voltage of the micro-emitting diode 3202 is increased, The transparency of the display device 20 is reduced.

Please refer to FIG. 4, the microluminescent diode 3202 of the present invention is, for example, a horizontal microluminescent diode 3202, as shown in FIG. 4 is a schematic diagram of the horizontal microluminescent diode of the present invention, and FIG. 4 is also a pixel unit 10 Side sectional view. The display device 20 has a cathode line 40 penetrating through a plurality of pixel units 10. In one pixel unit 10, the cathode line 40 is electrically connected to the cathode of the organic light emitting diode 3002, and the anode line 42b is electrically connected to the organic light emitting diode. The anode, the cathode line 40 and the anode line 42b of the body 3002 supply current to the organic light emitting diode 3002. In the same pixel unit 10, a conductive portion 42c electrically connected to the cathode is provided on the right side of the horizontal micro-emitting diode 3202, and the conductive portion 42c is electrically connected to the common cathode line 40, and the micro-emitting diode An anode line 42a electrically connected to the anode is provided on the left side of the body 3202, and the cathode line 40 and the anode line 42a supply a current to the microluminescent diode 3202.

To further explain, in each pixel unit 10, the cathode circuit 40 and the conductor portion 42c of the microluminescent diode 3202 and the anode circuit 42a of the microluminescent diode 3202 can control the microluminescent diode 3202. The voltage or current is operated to control the light-emitting intensity of the micro-light-emitting diode 3202, that is, to control the light flux of the micro-light-emitting diode 3202, thereby generating the aforementioned transparency.

Please refer to FIG. 5A and FIG. 5B. FIG. 5A is a schematic diagram of the pixel unit composition in the embodiment of the present invention, and FIG. 5B is a schematic diagram of the optical simulation data of the pixel unit of FIG. 5A.

FIG. 5A shows a configuration of an organic light emitting diode 3002 and a micro light emitting diode 3202 in a single pixel unit 10. In this embodiment, one organic light emitting diode 3002 and a plurality of (for example: three ) Configuration specifications of micro-luminescent diode 3202, for example: a single organic light-emitting diode The size of 3002 is 33μm × 99μm. The luminous flux of the organic light emitting diode 3002 is 400 lumens (lm), while the size of a single microluminescent diode 3202 is 8μm × 14μm. The luminous flux is 140 lumens (lm). At the corresponding positions of the organic light-emitting diode 3002 and the micro-light-emitting diode 3202 in the pixel unit 10, the display state of the luminous intensity is formed as shown in FIG. 5B. To achieve the aforementioned effects.

In a single pixel unit 10, the light-emitting area ratio of a single organic light-emitting diode 3002 and a plurality of (for example: three) micro-light-emitting diodes 3202 is about 1: 2. This design makes the transparent area more obvious and The light will not interfere with each other, which is also related to the size parameters of the micro-luminescent diode 3202. In the figure, the brightness of the display area 3010 is sufficient, and the brightness of the see-through area 3210 is sufficient to form transparency. Moreover, the brightness range produced by the micro-emitting diode 3202 in the see-through area 3210 will not affect the organic light-emitting diode 3002 in the display area. The brightness range of 3010 can still maintain the sharpness of the text or image displayed by the organic light emitting diode 3002.

Please refer to FIG. 6A and FIG. 6B. FIG. 6A and FIG. 6B are schematic diagrams of two application scenarios of the display device of the present invention in a conference room compartment. The three floor-to-ceiling windows in FIG. 6A are transparent conference room compartments 50. For example, using the display device 20 of the present invention, the organic light emitting diode 3002 can display images such as “AUO ...” and / or other characters, and The display device 20 has transparency and can be seen through, and can clearly see the situation in the conference room.

In FIG. 6B, the micro-light-emitting diode 3202 has been driven to emit light, and the display device 20 has an opaque appearance. The conference room compartment 50 cannot be seen through from the outside of the conference room, that is, the situation in the conference room cannot be seen.

Therefore, a feature of the display device 20 of the present invention is that the state of being powered on will be opaque and the state of being unpowered will be transparent, which is different from some conventional displays. To further explain, the display device 20 is used to display images such as images or text, and a part of the organic light emitting diode display module 30 is used to display the images, such as the aforementioned "AUO ... Wait", The other organic light emitting diodes 3002 in the organic light emitting diode display module 30 are adjusted to emit light to produce a transparency consistent with the see-through region 3210. That is, when the transparent state as shown in FIG. 6A is required, neither the organic light-emitting diode 3002 nor the micro-light-emitting diode 3202 that is not used to display the image is powered on; when the opaque state is required as shown in FIG. 6B, it is not necessary. Both the organic light-emitting diode 3002 and the micro-light-emitting diode 3202 used to display the image are energized to generate consistent transparency. At this time, although the organic light-emitting diode 3002 that displays the image and the organic light-emitting diode that does not display the image Both 3002 are powered on, but their operating voltages are different. Taking the example of FIG. 6B as an example, the organic light emitting diode 3002 that displays the image can display "AUO ... etc.", for example: pure red "AUO ... etc." ", The organic light-emitting diode 3002 that does not display this image will display a white mist-like background.

Please refer to FIG. 7, which is a schematic diagram of an embodiment of the present invention to form a watermark using a micro-luminescent diode. When only a part of the micro-light-emitting diode 3202 emits light in the entire display device 20 to generate the first transparency described above, the general effect like a watermark 62 can be produced. As shown in the figure, the organic light-emitting diode 3002 emits light and can display text 60 "AUO" or other text / graphics, controlling the light emitting degree of the red organic light emitting diode 3020, the green organic light emitting diode 3022, and the blue organic light emitting diode 3024 can also make the text 60 produce a variety of colors. Part of the micro-light-emitting diode 3202 emits light, and the first transparency shown can combine the effect of the "best quality" of the watermark 62. The other micro-light-emitting diodes 3202 are transparent when they do not emit light. The chromaticity and / or gray scale of the watermark 62 is different from the chromaticity and / or gray scale of the text 60 to prevent the two from interfering with each other and cannot be distinguished individually.

Therefore, with the display device 20 and the pixel unit 10 capable of changing the transparent state provided by the present invention, the arrangement of the organic light emitting diode display module 30 not only enables the display device 20 to display transparently, but also uses a micro light emitting diode. The volume display module 32 is set to change the transparency, or to control different levels of transparency in different areas, which not only makes the display effect better but also the display style more diverse and rich, and the structure of the display device 20 is not too complicated, which is beneficial to Production and commercialization.

With the above detailed description of the preferred embodiments, it is hoped that the features and spirit of the present invention can be more clearly described, and the scope of the present invention is not limited by the preferred embodiments disclosed above.
