[0019] The following is an explanation of the implementation methods of the "transparent display" disclosed in the present invention through specific embodiments. Those skilled in the art can understand the advantages and effects of the present invention from the contents disclosed in this specification. The present invention can be implemented or applied through other different specific embodiments, and the details in this specification can also be modified and changed in various ways based on different viewpoints and applications without departing from the concept of the present invention. In addition, it should be stated in advance that the drawings of the present invention are only simple schematic illustrations and are not depicted according to actual dimensions. The following embodiments will further explain the relevant technical contents of the present invention in detail, but the disclosed contents are not intended to limit the scope of protection of the present invention. In addition, the term "or" used in this article may include any one or more combinations of the associated listed items depending on the actual situation.

[0020] See also Figures 1 to 10 As shown, the present invention provides a transparent display D (or a light-transmitting display or a see-through display), which at least includes: a liquid crystal module 1, a light-emitting diode module 2 and a control module 3, wherein the liquid crystal module 1 includes a plurality of liquid crystal units 10, the light-emitting diode module 2 includes a plurality of light-emitting diode chips 20, and the control module 3 is configured to be electrically connected to the liquid crystal module 1 and the light-emitting diode module 2. Thus, the control module 3 can be configured to control the liquid crystal molecules 10M of each liquid crystal unit 10 to produce a twist angle change, so that each liquid crystal unit 10 forms an opaque area or a light-transmitting area.

[0021] [First embodiment]

[0022] See also Figures 1 to 6 As shown, the first embodiment of the present invention provides a transparent display D, which at least includes: a liquid crystal module 1 , a light emitting diode module 2 and a control module 3 .

[0023] Furthermore, with Figure 1 , Figure 2 and Figure 4As shown, the liquid crystal module 1 includes a plurality of liquid crystal units 10 that can operate independently of each other, and the plurality of liquid crystal units 10 of the liquid crystal module 1 can correspond to the plurality of light-emitting diode chips 20 of the light-emitting diode module 2. For example, the liquid crystal module 1 can include at least a first transparent substrate 11, a second transparent substrate 12, a first polarizing plate 13 disposed on the bottom end of the first transparent substrate 11, a first transparent electrode layer 14 (such as a pixel electrode) disposed on the top end of the first transparent substrate 11, a first alignment film 15 disposed on the first transparent electrode layer 14, a second polarizing plate 16 disposed on the top end of the second transparent substrate 12, a second transparent electrode layer 17 (such as a common electrode) disposed on the bottom end of the second transparent substrate 12, and a second alignment film 18 disposed on the second transparent electrode layer 17, and the plurality of liquid crystal units 10 can be arranged between the first alignment film 15 and the second alignment film 18. That is, the liquid crystal module 1 can be a liquid crystal panel that does not include a color filter. However, the above example is only one feasible embodiment and is not intended to limit the present invention.

[0024] Furthermore, with Figure 1 , Figure 3 and Figure 4As shown, the LED module 2 includes a plurality of LED chips 20 that can operate independently of each other, and the LED module 2 can be configured on the liquid crystal module 1 to provide a predetermined image (or a predetermined picture) to the user in front of the transparent display D for viewing. In addition, the LED chip 20 can be configured to provide a front light source 20F and a back light source 20B opposite to the front light source 20F. For example, a plurality of LED chips 20 (such as mini LED, micro LED or any type of LED) can be divided into a plurality of red LED chips, a plurality of green LED chips and a plurality of blue LED chips, and the adjacent red LED chips, green LED chips and blue LED chips can cooperate with each other to form an image pixel of a predetermined image (that is, the predetermined image can be composed of a plurality of image pixels). In addition, each LED chip 20 of the LED module 2 can be electrically connected to the liquid crystal module 1 through two conductive materials 20S (such as solder balls or any other type of conductive material), so that the liquid crystal module 1 and the LED module 2 can be electrically connected to each other. In addition, the front light source 20F generated by each LED chip 20 can be projected from a light emitting surface 2001 of the LED chip 20, and the back light source 20B generated by each LED chip 20 can be projected from an electrode surface 2002 of the LED chip 20. It is worth noting that each LED chip 20 includes two conductive pads 20P disposed on the electrode surface 2002, and no reflective layer is disposed on the electrode surface 2002 of each LED chip 20 (for example, no distributed Bragg reflector (DBR) is formed on the electrode surface 2002 of each LED chip 20), so the back light source 20B generated by each LED chip 20 can be smoothly projected from the electrode surface 2002 of the LED chip 20. However, the above example is only one feasible embodiment and is not intended to limit the present invention.

[0025] Furthermore, with Figure 1 and Figure 4As shown, the control module 3 can be configured to be electrically connected to the liquid crystal module 1 and the light-emitting diode module 2. For example, the control module 3 can be a central processing unit (CPU), a digital signal processor (DSP), a microprocessor (MPU), a microcontroller (MCU), etc. In addition, when the control module 3 is configured to turn on the light-emitting diode chip 20, the light-emitting diode chip 20 can be configured to provide a front light source 20F and a back light source 20B opposite to the front light source 20F. In addition, when the control module 3 is configured to be electrically connected to the first light-transmitting electrode layer 14 and the second light-transmitting electrode layer 17, the control module 3 can be configured to control the liquid crystal molecules 10M of each liquid crystal unit 10 to produce a twist angle change, thereby allowing light to pass through the liquid crystal unit 10 or blocking light from passing through the liquid crystal unit 10. It is worth noting that when the control module 3 can be configured to turn on the light-emitting diode chip 20 (for example, turning on Figure 4 When the top two LED chips 20 and the bottom two LED chips 20 are turned on, the control module 3 can be configured to control the corresponding liquid crystal unit 10 to form an opaque area, thereby blocking the back light source 20B generated by the LED chip 20 from passing through the corresponding liquid crystal unit 10 (that is, the back light source 20B generated by the LED chip 20 cannot pass through the corresponding liquid crystal unit 10 through the opaque area formed by the corresponding liquid crystal unit 10). In addition, when the control module 3 can be configured to turn off the LED chip 20 (for example, turn off Figure 4 When the middle two LED chips 20 are shown, the control module 3 can be configured to control the corresponding liquid crystal unit 10 to form a light-transmitting area, thereby allowing the ambient light E to pass through the corresponding liquid crystal unit 10. However, the above example is only one feasible embodiment and is not intended to limit the present invention.

[0026] For example, if Figure 5As shown, when the control module 3 can be configured to simultaneously turn on the multiple LED chips 20 of the LED module 2, the control module 3 can be configured to simultaneously control the liquid crystal molecules 10M of the multiple liquid crystal units 10 to produce a twist angle change, so that each liquid crystal unit 10 forms an opaque area, thereby blocking the back light source 20B generated by each LED chip 20 from passing through the corresponding liquid crystal unit 10. Therefore, when the user in front of the transparent display D views a predetermined image through the multiple front light sources 20F generated by the LED chips 20, other people behind the transparent display D will not see the back light source 20B generated by the LED chips 20 at all. It is worth noting that when the control module 3 can be configured to simultaneously turn on the multiple LED chips 20 of the LED module 2, although the control module 3 is configured to simultaneously control the multiple liquid crystal units 10 to form multiple opaque areas, the transparent display D can still provide a sufficient light-transmitting effect to the user in front of the transparent display D through "a gap space formed between the multiple LED chips 20" (that is, the user can see the scene behind the transparent display D through the light-transmitting effect provided by the transparent display D). In this way, the liquid crystal module 1 can be configured to enhance the contrast of the predetermined image provided by the LED module 2 and reduce the halo phenomenon of the predetermined image provided by the LED module 2. However, the above example is only one feasible embodiment and is not intended to limit the present invention.

[0027] For example, if Figure 6 As shown, when the control module 3 can be configured to simultaneously turn off the multiple LED chips 20 of the LED module 2, the control module 3 can be configured to simultaneously control the liquid crystal molecules 10M of the multiple liquid crystal units 10 to produce a twist angle change, so that each liquid crystal unit 10 forms a light-transmitting area, thereby allowing ambient light E to pass through the multiple liquid crystal units 10. Therefore, the transparent display D can simultaneously provide the user with a light-transmitting effect with higher light transmittance through "multiple light-transmitting areas formed by multiple liquid crystal units 10" and "a gap space formed between multiple LED chips 20". However, the above example is only one feasible embodiment and is not intended to limit the present invention.

[0028] It is worth noting that Figure 4 , Figure 5 or Figure 6As shown, the transparent display D may further include a light-transmitting cover plate 4, and the light-transmitting cover plate 4 may be configured to cover the plurality of LED chips 20 of the LED module 2. For example, the light-transmitting cover plate 4 may be a glass substrate or any type of light-transmitting substrate, and the light-transmitting cover plate 4 may directly contact the plurality of LED chips 20 or be separated from the plurality of LED chips 20 by a predetermined distance. However, the above example is only one feasible embodiment and is not intended to limit the present invention.

[0029] [Second embodiment]

[0030] See also Figures 1 to 3 as well as Figure 7 As shown, the second embodiment of the present invention provides a transparent display D, which at least includes: a liquid crystal module 1, a light emitting diode module 2 and a control module 3. Figure 7 and Figure 4 It can be seen from the comparison that the main difference between the second embodiment of the present invention and the first embodiment is that: in the second embodiment, the light-emitting diode module 2 includes a light-transmitting carrier substrate 21, and each light-emitting diode chip 20 can be electrically connected to the light-transmitting carrier substrate 21 through two conductive materials 20S. In addition, since the light-transmitting carrier substrate 21 can be configured to carry a plurality of light-emitting diode chips 20 (that is, the plurality of light-emitting diode chips 20 do not need to be arranged on the liquid crystal module 1 as in the first embodiment), the liquid crystal module 1 and the light-emitting diode module 2 can be electrically insulated from each other, and the liquid crystal module 1 and the light-emitting diode module 2 can be independently manufactured and then assembled.

[0031] [Third embodiment]

[0032] See also Figures 1 to 3 , Figure 8 and Fig. 9 As shown, the third embodiment of the present invention provides a transparent display D, which at least includes: a liquid crystal module 1, a light emitting diode module 2 and a control module 3. Figure 8 and Figure 4 It can be seen from the comparison that the main difference between the third embodiment of the present invention and the first embodiment is that: in the third embodiment, the LED module 2 has a gap space formed between the plurality of LED chips 20, a portion of the plurality of liquid crystal units 10 of the liquid crystal module 1 can correspond to the plurality of LED chips 20 of the LED module 2, and another portion of the plurality of liquid crystal units 10 of the liquid crystal module 1 can correspond to the gap space of the LED module 2 at the same time. For example, the plurality of LED chips 20 can be arranged in a predetermined shape, a gap channel G is formed between every two adjacent LED chips 20, and the gap space can be composed of a plurality of gap channels G connected to each other ( Figure 8 The multiple gap channels G shown are only schematic side views and are not intended to limit the actual positions of the multiple gap channels G). However, the above example is only one feasible embodiment and is not intended to limit the present invention.

[0033] It is worth noting that Figure 8 As shown, since another part of the multiple liquid crystal units 10 of the liquid crystal module 1 can correspond to the gap space of the light-emitting diode module 2 at the same time, the control module 3 can be configured to simultaneously control the liquid crystal molecules 10M of another part of the multiple liquid crystal units 10 to produce a twist angle change, so that each of the other parts of the multiple liquid crystal units 10 forms a light-transmitting area, thereby allowing the ambient light E to pass through the multiple gap channels G. Therefore, the transparent display D can simultaneously provide the user with a light-transmitting effect with higher light transmittance through "a plurality of light-transmitting areas formed by the multiple liquid crystal units 10" and "a gap space (i.e., a plurality of gap channels G) formed between the multiple light-emitting diode chips 20".

[0034] It is worth noting that with Figure 1 and Figure 8 As shown, the control module 3 can be configured to simultaneously (or synchronously) send a liquid crystal control signal 301 and an image control signal 302 to the liquid crystal module 1 and the light emitting diode module 2, respectively, so that the multiple liquid crystal units 10 of the liquid crystal module 1 and the multiple light emitting diode chips 20 of the light emitting diode module 2 can react synchronously (that is, the control module 3 does not need to control the liquid crystal module 1 through the ambient light information provided by the ambient light sensor). For example, according to the liquid crystal control signal 301 and the image control signal 302 provided by the control module 3, the liquid crystal unit 10 and the light emitting diode chip 20 can be turned on synchronously, turned off synchronously, turned on and turned off synchronously, or turned off and turned on synchronously, and the liquid crystal unit 10 and the light emitting diode chip 20 can correspond to each other or not correspond to each other, for example, the liquid crystal unit 10 and the light emitting diode chip 20 can also be staggered. Furthermore, when an LED chip 20 is turned off by the control of the image control signal 302 provided by the control module 3 (the LED chip 20 presents a black pattern or black pixel at this time), the liquid crystal unit 10 corresponding to the gap channel G surrounding the LED chip 20 can be synchronously turned off by the control of the liquid crystal control signal 301 (at this time, the ambient light E cannot pass through the liquid crystal unit 10 corresponding to the gap channel G surrounding the LED chip 20), thereby improving the contrast of the black pattern or black pixel presented by the LED chip 20.

[0035] It is worth noting that with Figure 1 and Fig. 9As shown, the transparent display D may further include an ambient light sensor 5, which is electrically connected to the control module 3, and the ambient light sensor 5 may be configured to sense the irradiation light S behind the transparent display D. For example, the ambient light sensor 5 may be configured to be disposed at any position of the liquid crystal module 1 or the light emitting diode module 2, or the ambient light sensor 5 may also be disposed on another circuit substrate (not shown) instead of being disposed on the liquid crystal module 1 or the light emitting diode module 2. In addition, the light intensity information of the irradiation light S sensed by the ambient light sensor 5 may be transmitted to the control module 3 via a wired or wireless method. Furthermore, when the illumination light S (such as outdoor sunlight or indoor lighting) behind the liquid crystal module 1 exceeds a predetermined intensity (such as a predetermined light intensity value that affects the user's viewing of the predetermined image provided by the light-emitting diode module 2), the control module 3 can be configured to simultaneously control the plurality of liquid crystal units 10 to form a whole-surface light-shielding area (for example, the whole-surface light-shielding area can be provided by a plurality of liquid crystal units 10 that are closely arranged or connected to each other), thereby blocking the illumination light S with the predetermined intensity from being transmitted to the light-emitting diode module 2 through the plurality of liquid crystal units 10. In other words, when the control module 3 is configured to determine that the illumination light S sensed by the ambient light sensor 5 exceeds the predetermined intensity, the control module 3 can be configured to simultaneously control the liquid crystal molecules 10M of the plurality of liquid crystal units 10 to produce a twist angle change, so that the plurality of liquid crystal units 10 can cooperate with each other to form a whole-surface light-shielding area, thereby blocking the illumination light S with the predetermined intensity from being transmitted to the light-emitting diode module 2 through the plurality of liquid crystal units 10. It is worth noting that the light transmittance of the entire light shielding area formed by the cooperation of the plurality of liquid crystal units 10 can be adjusted according to the intensity of the irradiated light S sensed by the ambient light sensor 5 or different needs of the user (for example, the predetermined intensity can be set according to different needs of the user). However, the above example is only one feasible embodiment and is not intended to limit the present invention.

[0036] [Fourth embodiment]

[0037] See also Figures 1 to 3 as well as Fig.10 As shown, the fourth embodiment of the present invention provides a transparent display D, which at least includes: a liquid crystal module 1, a light emitting diode module 2 and a control module 3. Fig.10 and Figure 8It can be seen from the comparison that the main difference between the fourth embodiment of the present invention and the third embodiment is that in the fourth embodiment, the light-emitting diode module 2 includes a light-transmitting carrier substrate 21, and each light-emitting diode chip 20 can be electrically connected to the light-transmitting carrier substrate 21 through two conductive materials 20S. In addition, since the light-transmitting carrier substrate 21 can be configured to carry a plurality of light-emitting diode chips 20 (that is, the plurality of light-emitting diode chips 20 do not need to be disposed on the liquid crystal module 1 as in the third embodiment), the liquid crystal module 1 and the light-emitting diode module 2 can be electrically insulated from each other, and the liquid crystal module 1 and the light-emitting diode module 2 can be independently manufactured and then assembled.

[0038] [Beneficial Effects of Embodiments]

[0039] One of the beneficial effects of the present invention is that a transparent display D provided by the present invention can form an opaque area or a translucent area in the liquid crystal unit 10 through the technical solutions of "the liquid crystal module 1 includes a plurality of liquid crystal units 10", "the light-emitting diode module 2 includes a plurality of light-emitting diode chips 20", "the control module 3 is configured to be electrically connected to the liquid crystal module 1 and the light-emitting diode module 2", and "the control module 3 can be configured to control the liquid crystal molecules 10M of each liquid crystal unit 10 to produce a twist angle change", thereby allowing light to pass through the liquid crystal unit 10 or blocking light from passing through the liquid crystal unit 10.

[0040] For example, when the control module 3 can be configured to turn on the LED chip 20, the control module 3 can be configured to control the corresponding liquid crystal unit 10 to form an opaque area, thereby blocking the back light source 20B generated by the LED chip 20 from passing through the corresponding liquid crystal unit 10. Further, when the control module 3 can be configured to turn on multiple LED chips 20 of the LED module 2 at the same time, the control module 3 can be configured to simultaneously control the liquid crystal molecules 10M of the multiple liquid crystal units 10 to change their twist angles, so that each liquid crystal unit 10 forms an opaque area, thereby blocking the back light source 20B generated by each LED chip 20 from passing through the corresponding liquid crystal unit 10.

[0041] For example, when the control module 3 is configured to turn off the LED chip 20, the control module 3 is configured to control the corresponding liquid crystal unit 10 to form a light-transmitting area, thereby allowing the ambient light E to pass through the corresponding liquid crystal unit 10. Furthermore, when the control module 3 is configured to turn off multiple LED chips 20 of the LED module 2 at the same time, the control module 3 is configured to control the liquid crystal molecules 10M of the multiple liquid crystal units 10 to change their twist angles at the same time, so that each liquid crystal unit 10 forms a light-transmitting area, thereby allowing the ambient light E to pass through the multiple liquid crystal units 10.

[0042] For example, when the irradiation light S exceeds a predetermined intensity, the control module 3 can be configured to simultaneously control the plurality of liquid crystal units 10 to form a whole-surface light-shielding area, thereby blocking the irradiation light S with a predetermined intensity from being transmitted to the light-emitting diode module 2 through the plurality of liquid crystal units 10. Further, when the control module 3 can be configured to determine that the irradiation light S sensed by the ambient light sensor 5 exceeds a predetermined intensity, the control module 3 can be configured to simultaneously control the liquid crystal molecules 10M of the plurality of liquid crystal units 10 to produce a twist angle change, so that the plurality of liquid crystal units 10 cooperate with each other to form a whole-surface light-shielding area, thereby blocking the irradiation light S with a predetermined intensity from being transmitted to the light-emitting diode module 2 through the plurality of liquid crystal units 10.

[0043] It is worth noting that the ambient light sensor 5 can be omitted in the first, second and fifth embodiments. That is, the control module 3 can be configured to directly control the liquid crystal module 1 through the liquid crystal control signal 301, without the need to control the liquid crystal module 1 through the ambient light information provided by the ambient light sensor.
