Detailed Description

Referring to fig. 1 and 2, a photovoltaic display assembly 10 is provided. The photovoltaic display assembly 10 includes a display panel 110 and a photovoltaic cell panel 120. The display panel 110 has a light emitting surface 111, and includes a plurality of light emitting devices 112 disposed at intervals on the light emitting surface 111. The photovoltaic cell panel 120 is attached to the light emitting surface 111. The photovoltaic cell panel 120 is provided with a plurality of through holes 121. The plurality of through holes 121 are disposed in one-to-one correspondence with the plurality of light emitting devices 112. The photovoltaic panel 120 is electrically connected to the plurality of light emitting devices 112, and is configured to convert solar energy into electrical energy and supply power to the plurality of light emitting devices 112.

In one embodiment, the display panel 110 may be made of transparent materials such as glass, polyethylene terephthalate (PET), Polycarbonate (PC), etc. to increase the permeability of the display panel 110, and to facilitate the light emitting devices 112 to be mounted on the display panel 110 by adhesion or the like.

In one embodiment, the light emitting device 112 may be a Light Emitting Diode (LED) lamp. An LED is a semiconductor electronic component that converts electrical energy into light energy. The LED is composed of a PN junction, and when a forward voltage is applied to the LED, holes injected into the N region from the P region and electrons injected into the P region from the N region are recombined with the electrons in the N region and the holes in the P region within a range of several micrometers near the PN junction respectively to generate spontaneously-radiated photons. The LED has the advantages of low voltage required during working, and far lower heat productivity than common illuminating lamps with the same power, so that the LED has the advantages of energy conservation and environmental protection.

Referring to fig. 3, in the present embodiment, the through holes 121 may be arranged in a matrix. The photovoltaic cell panel 120 may be a CIGS (copper indium gallium selenide) photovoltaic cell panel 120. The CIGS photovoltaic cell panel 120 has a thickness of about 2mm to about 3mm and may be selected according to actual needs. Compared with a crystalline silicon and amorphous silicon photovoltaic cell, the CIGS photovoltaic cell has a wider absorbable spectral wavelength range, and can cover an infrared light region with the wavelength of 700-1220 nm besides the visible spectral range of the light absorbed by the crystalline silicon and amorphous silicon photovoltaic cell, so that the CIGS photovoltaic cell has higher photoelectric conversion efficiency.

In the photovoltaic display module 10 provided by the present application, the photovoltaic cell panel 120 is disposed on the light emitting surface 111 of the display panel 110, and sunlight directly irradiates on the photovoltaic cell panel 120. The photovoltaic cell panel 120 absorbs sunlight and converts the sunlight into electric energy to supply power to the display panel 110, so that the light energy is effectively utilized, and the electricity cost can be saved. Since the photovoltaic cell panel 120 can absorb sunlight, the sunlight can be prevented from being irradiated on the glass panel of the display panel 110, and thus, the problem of light pollution caused by reflection of the glass panel is effectively avoided. In addition, the photovoltaic cell panel 120 is provided with through holes 121 corresponding to the light emitting devices 112 one to one, and light emitted by the light emitting devices 112 can directly irradiate to the outside through the through holes 121, so that the permeability of the display screen is realized.

Referring to fig. 4, in one embodiment, the display panel 110 has a plurality of grooves 113 formed on a surface thereof. One of the light emitting devices 112 is correspondingly disposed in one of the grooves 113. The plurality of grooves 113 may be formed by a process such as etching, or may be formed by engraving with an engraving machine. The position of the light emitting device 112 on the display panel 110 may be restricted by the groove 113. And the light-emitting device 112 can be prevented from falling off, and the service life is prolonged.

In one embodiment, the display panel 110 may employ LED dot matrix display technology. It should be understood that, in the present embodiment, the light emitting device 112 may be an LED lamp. There are many LED arrays such as 4 × 4, 4 × 8, 5 × 7, 5 × 8, 8 × 8, 16 × 16, 24 × 24, and 40 × 40. Specifically, the plurality of grooves 113 may be designed in the dot matrix form, and one LED lamp is correspondingly disposed in one groove 113.

Referring to fig. 2 again, in an embodiment, the one light emitting device 112 may include a plurality of light emitting chips 1121. The plurality of light emitting chips 1121 is configured to emit light of different colors. The light emitting device 112 may be an LED lamp, and the light emitting chip 1121 may be an LED chip. It is understood that the LED chip can emit light of different wavelengths (i.e., different colors) because electrons and holes in different semiconductor materials are in different energy states and thus release different energy when the electrons and holes recombine.

In one embodiment, the gallium phosphide LED chip can be used to emit red light, the gallium phosphide LED chip can be used to emit green light, the silicon carbide LED chip can be used to emit yellow light, and the indium gallium nitride LED chip can be used to emit blue light. In one embodiment, each of the LED lamps may include LED chips of different colors, and the plurality of LED chips are individually controlled to mix out light of different colors. The LED lamps can display different colors according to requirements. The LED lamps can form different texts or graphics according to different displayed colors. Due to the characteristics of the LED, the LED display screen has the advantages of high transparency, high brightness, low working voltage, low power consumption, large scale, long service life, impact resistance and stable performance.

In one embodiment, an LED chip may be disposed in one of the grooves 113, and then encapsulated by resin or plastic, thereby being connected to an external circuit and a computer. The display panel 110 may be formed by several tens of thousands to several hundreds of thousands of LED chips arranged in a matrix. The LED chips in the matrix are made of different materials and can emit light with different colors. Specifically, the light emitted by the LED chip may be in three primary colors, red, green, and blue, to serve as different pixel points, thereby implementing image rendering. It should be understood that, as the display panel 112 capable of displaying images, the size of the LED chips should be small enough, and the distance between two adjacent LED chips should be small enough, so that the red, green and blue lights can be mixed, thereby making the displayed picture color more realistic. The display panel 112 may display still pictures or moving videos through various driving circuits and computer program control. Because the number of the LED chips on the display panel 112 is large, and the distance between two adjacent LED chips is small, the picture displayed by the display panel 112 has the advantages of bright and fine color and strong stereoscopic impression.

In one embodiment, the fabrication process of the CIGS photovoltaic cell panel 120 is as follows:

s10, a Mo (molybdenum) metal layer is plated on the glass substrate in a magnetron sputtering mode to serve as the positive electrode of the CIGS photovoltaic cell panel 120;

s20, plating a CIGS (copper indium gallium selenide) film layer in a magnetron sputtering mode to form a P-type semiconductor region of the photovoltaic cell panel 120;

s30, forming a CdS (cadmium sulfide) film layer on the CIGS (copper indium gallium selenide) film layer in a chemical deposition mode, wherein the CdS film layer is used for forming an N-type semiconductor region of the photovoltaic cell panel 120;

s40, after the above steps are completed, an ITO (indium tin oxide) metal oxide layer is plated through magnetron sputtering and is used for forming the cathode of the photovoltaic cell panel 120;

in the above step of plating each film layer, a plurality of sub-cell arrays, positive and negative electrode systems of the photovoltaic cell panel 120 are formed by processes of scribing, edge cleaning, and the like.

In the process of manufacturing each film layer by magnetron sputtering in the above embodiment, high-energy incident ions bombard the surface of the target material to sputter target material atoms or molecules, so that the target material atoms or molecules are deposited on the substrate with very high energy, and the kinetic energy of the target material atoms or molecules is converted into heat energy, thereby enhancing the adhesion of the sputtered atoms or molecules to the substrate. Therefore, the film layer manufactured by adopting the magnetron sputtering mode is firmer and higher in compactness under the high-temperature and high-energy plasma state. In addition, the film layer formed by magnetron sputtering has lower absorptivity to light and higher transmittance. Therefore, the magnetron sputtering is used to fabricate the film layer of the photovoltaic cell panel 120, so that the light absorption rate can be increased, and the photoelectric conversion efficiency of the photovoltaic cell panel 120 can be increased. In addition, a film layer of the display screen can be manufactured by adopting magnetron sputtering, so that the permeability of the display screen can be increased.

In one embodiment, the through holes 121 may be formed by screen printing a layer of protective paste on the surface of the CIGS photovoltaic cell panel 120 to protect the photovoltaic cell panel 120 during the subsequent fabrication of the through holes 121. The specific process can be as follows:

s10, reserving the position of the through hole 121 at the position corresponding to the groove 113 when designing the screen printing plate;

s20; the position of the through hole 121 is not printed with the protective glue in a silk-screen manner, and the position of the through hole 121 is removed with the protective glue in a silk-screen manner;

s30; after the screen printing of the protective glue is finished, curing the screen printing protective glue by using UV curing equipment;

s40; the photovoltaic cell panel 120 is placed into sand blasting equipment for sand blasting, fine quartz and aluminum oxide particles are driven to collide with the photovoltaic cell panel 120 by high-speed flowing gas, the position of the protective glue is subjected to silk screen printing without being influenced, and the position of the protective glue is not subjected to silk screen printing and can be removed by repeated collision of the fine particles.

The photovoltaic cell panel 120 may be selectively removed through the above steps to form the through hole 121, so that the light emitted from the display panel 110 passes through the through hole 121.

In one embodiment, the photovoltaic display assembly 10 further comprises a first adhesive layer 160. The first adhesive layer 160 is disposed between the display panel 110 and the photovoltaic cell panel 120. The photovoltaic cell panel 120 is attached to the display panel 110 by the first adhesive layer 160. The first adhesive layer 160 may be PVB (polyvinyl butyral) adhesive. The PVB glue has better corrosion resistance, antirust capacity, adhesion and water resistance. The first adhesive layer 160 is made of PVB adhesive, and can permanently adhere the display panel 110 and the photovoltaic cell panel 120.

In one embodiment, the through hole 121 may be designed in any shape, for example, a circle, a square, a trapezoid, a heart, etc., according to the shape of the photovoltaic display module 10.

In one embodiment, the projection of the through-hole 121 on the display panel 110 covers the recess 113. The light emitting device 112 is disposed in the groove 113. In other words, the size of the light emitting device 112 is comparable to the groove 113. It should be understood that the size of the through hole 121 should be slightly larger than the light emitting device 112. Therefore, the light emitted from the light emitting device 112 can pass through the through hole 121. Specifically, when the groove 113 and the through hole 121 are both circular, the diameter of the through hole 121 should be slightly larger than that of the groove 113. The diameter of the through-hole 121 may be 0.6mm to 5 mm. If the diameter of the through hole 121 is too small, the display effect is affected by shading. If the diameter of the through hole 121 is too large, the light receiving area of the photovoltaic cell panel 120 is reduced, and the power generation efficiency of the photovoltaic cell panel 120 is affected. Specifically, the selection may be different according to the size of the display panel 110 and the distance between the two adjacent light emitting devices 112.

It should be understood that the distance d between the two connected light emitting devices 112 can be determined according to the requirements of display effect, scene and viewing distance. Specifically, when the light emitting device 112 includes LED chips of a plurality of colors, the size of d determines the pixels of the display panel 110.

Referring to fig. 5, in one embodiment, the through hole 121 is provided with a condensing lens 122. For concentrating the light emitted by the light emitting device 112. In one embodiment, the condenser lens 122 may be a convex lens. The light emitting device 112 may be viewed approximately as a point light source. The light emitting device 112 may be located at a focal point of the convex lens, so that light emitted by the light emission is condensed into parallel rays through the convex lens, thereby increasing efficiency of light passing through the through hole 121 and improving a display effect.

Referring to fig. 6, in an embodiment, the inner cross-section of the through hole 121 gradually increases from a side of the light emitting device 112 to a direction away from the light emitting device 112. The through hole 121 may be approximately in the shape of an inverted truncated cone, so that more light emitted from the light emitting device 112 can pass through the through hole 121, thereby improving light transmittance and improving a display effect.

Referring to fig. 7-8, in one embodiment, the photovoltaic display assembly 10 further comprises a light reflector 123. The light reflecting means 123 may be disposed on an inner wall of the through hole 121 or on an inner wall of the groove 113. The light reflecting means 123 may be used to condense the light emitted from the light emitting means 112 by reflection. It should be understood that the light reflecting means 123 may be a mirror.

Referring to fig. 7, in an embodiment, the light reflecting device 123 may be disposed on an inner wall of the through hole 121, for improving the light transmittance of the through hole 121, and preventing the light emitted from the light emitting device 112 from being absorbed by the photovoltaic cell panel 120. The light emitting device 112 is an LED lamp bead including a plurality of LED chips. The LED lamp bead can be approximately regarded as a point light source. The light emitted by the LED lamp bead is dispersed in all directions perpendicular to the surface of the lamp bead due to the shape of the lamp bead. Part of the diffused light may be reflected by the light reflecting means 123 to pass through the through hole 121, thereby improving the light transmittance of the through hole 121.

Referring to fig. 8, in another embodiment, the light reflecting means 123 may be disposed on an inner wall of the groove 113 for condensing the light emitted from the light emitting means 112. The light emitting device 112 is an LED lamp bead including a plurality of LED chips. The LED lamp bead can be approximately regarded as a point light source. The light emitted by the LED lamp beads is diffused towards the periphery, and the reflecting device 123 can reflect part of the diffused light, so that the luminous efficiency of the LED lamp beads is enhanced. Thereby allowing more light to pass through the through-hole 121, thereby improving the light transmittance of the through-hole 121.

Referring again to fig. 4, in one embodiment, the display panel 110 further has a back surface 114. The rear surface 114 is disposed opposite to the light emitting surface 111. The photovoltaic display assembly 10 further includes an encapsulation panel 130, the encapsulation panel 130 being attached to the back side 114. The encapsulation panel 130 may protect the display panel 110 from water oxygen contacting the display panel 110 and affecting the lifespan thereof.

Referring again to fig. 1-2, in one embodiment, the photovoltaic display assembly 10 further includes a second adhesive layer 170. The second adhesive layer 170 is disposed between the package panel 130 and the display panel 110. The package panel 130 is attached to the back surface 114 of the display panel 110 by the second adhesive layer 170. It should be understood that the second adhesive layer 170 can also be PVB adhesive.

In one embodiment, the photovoltaic display assembly 10 further comprises a transparent panel 140 attached to a surface of the photovoltaic cell panel 120 facing away from the display panel 110. The transparent panel 140 may protect the photovoltaic cell panel 120 from oxidation or corrosion of the photovoltaic cell panel 120, thereby extending the lifetime of the photovoltaic cell panel 120.

In one embodiment, the photovoltaic display assembly 10 further comprises a third adhesive layer 180. The third adhesive layer 180 is disposed between the transparent panel 140 and the display panel 110. The transparent panel 140 is attached to the surface of the photovoltaic cell panel 120 facing away from the display panel 110 by the third adhesive layer 180. It should be understood that the third adhesive layer 180 may also be PVB adhesive.

In one embodiment, the photovoltaic display assembly 10 may further include an energy storage device. The energy storage devices are electrically connected to the photovoltaic cell panel 111 and the display panel 110, respectively. The energy storage device can store the electric energy generated by the photovoltaic cell panel 111 and supply power to the display panel 110 at night or in the case of insufficient illumination. The energy storage device can reasonably utilize electric energy and avoid waste.

It should be understood that the photovoltaic display structure further includes a conductive line disposed on the display panel 110. The light emitting device 112 is connected to an external control circuit through the wire. In one embodiment, the wire may be a metal or alloy wire, such as a copper or tin-plated copper wire. The tinned copper wire is more beneficial to welding the wire to the light-emitting device 112, and the connection is firmer, so that the service life is prolonged.

In another embodiment, the wires may be ITO leads 150. The light emitting device 112 may be an LED lamp. The LED lamp is connected to an external control circuit through the ITO lead 150. In this embodiment, the display panel 110 is a transparent glass substrate. A transparent metal oxide layer (ITO) is plated on the glass substrate by magnetron sputtering, and the ITO material has good conductivity and light transmittance, and can be used as a wire without affecting the light emitting efficiency of the display panel 110. The ITO wiring can be realized by plating an ITO layer and then removing unnecessary parts by ultraviolet exposure and alkali washing. The specific process is as follows:

before the ITO layer is plated, a layer of SiO2 film is plated to enhance the adhesion of the ITO layer and prevent alkali metal ions in the glass substrate from diffusing to the ITO layer which is plated subsequently, so that the polarity of the ITO layer is changed to influence the physical properties. And an ITO layer is plated subsequently, and the ITO layer can be well adhered with the SiO2 film layer, so that the adhesive force is improved. And after the ITO layer is coated, a layer of POSI photoresist is hung and coated on the ITO layer. The POSI photoresist mainly uses phenolic resin as a main material, uses diazonaphthoquinone type esterified substance as a material of a photosensitizer, and has the functions of sensing 365nm wavelength and resisting strong acid. After the POSI adhesive is irradiated by ultraviolet rays with the wavelength of 365nm, the diazonaphthoquinone compound is decomposed at the position of an exposure area irradiated by the ultraviolet rays to generate indene carboxylic acid, and the indene carboxylic acid is easily dissolved in dilute alkali water. The area which is not irradiated by the ultraviolet rays does not change and is not dissolved in the dilute alkaline water. Therefore, after ultraviolet exposure and alkaline washing, certain areas can be selectively reserved and removed. After the ITO layer is processed as described above, a portion of the ITO lead 150 is left, and the other portion is removed. Thus, a pattern of ITO leads 150 can be formed, and one end of the ITO leads 150 is soldered to the LED lamp and the other end is connected to an external control circuit. The external control circuit may include a controller. And the display of the LED display screen is realized through the control of the controller.

The application also provides a photovoltaic curtain wall. The photovoltaic curtain wall comprises a plurality of photovoltaic display assemblies 10. The photovoltaic display modules 10 are spliced on the wall body and used for power generation and display. Specifically, the package panel 130 may be disposed on the surface of the building wall by means of screwing, welding, riveting or adhering.

In another embodiment, the package panel 130 can be directly used as a wall of the building, and the photovoltaic panel 120 is disposed on a side outside the wall. In the two embodiments, the photovoltaic cell panel 120 is disposed at the front end of the display panel 110, so that the hot spot effect caused by shielding the photovoltaic cell panel 120 from the display panel 110 in front can be avoided. The hot plate effect means that due to the existence of local shielding, the current and voltage of some single cells in the photovoltaic cell panel 120 are changed, so that a local temperature rise is generated on the photovoltaic cell panel 120, and the safety and the service life of the photovoltaic cell panel 120 are seriously affected. Therefore, the photovoltaic cell panel 120 is disposed at the front end of the display panel 110, so that the photovoltaic cell panel 120 is not shielded by the display panel 110, and the hot spot effect can be effectively avoided, thereby improving the safety of the photovoltaic cell panel 120 and prolonging the service life of the photovoltaic cell panel 120.

It should be understood that the application of the photovoltaic display assembly 10 provided by the present application is not limited to the photovoltaic curtain wall, but can also be applied to outdoor billboards, display screens and other devices.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
