Fig. 1 is a schematic structural diagram of an embodiment of a display panel provided in the present application. As shown in fig. 1, the display panel 130 includes a reflective display module 131 and a light source module 132, the reflective display module 131 has a light exit surface 1311, and external light passes through the light source module 132, enters the reflective display module 131 from the light exit surface 1311 of the reflective display module 131, and is reflected by a reflective layer 1315 in the reflective display module 131, so as to implement reflective display. The Reflective Display module 131 is any Display module that displays light by reflecting light from the outside, such as a Reflective Liquid Crystal Display (RLCD) module and a Reflective electronic ink Display module.
The light source module 132 is disposed on the light emitting surface 1311 of the reflective display module 131, when the display panel is used in an environment with weak light, the light source module 132 is configured to emit light toward the light emitting surface 1311 of the reflective display module 131, and the reflective display module 131 reflects the light emitted from the light source module 132, so as to implement reflective display.
The light source module 132 includes a transparent substrate 133 and a light emitting module 134, the transparent substrate 133 is opposite to the light emitting surface 1311, the light emitting module 134 is disposed on a side of the transparent substrate 133 facing the reflective display module 131, and light emitted by the light emitting module 134 enters the reflective display module 131 from the light emitting surface 1311 of the reflective display module 131, is reflected by the reflective layer 1315 in the reflective display module 131, and then passes through the transparent substrate 133, thereby implementing reflective display.
As shown in fig. 3, the light emitting module 134 includes a driving circuit 1345 and a plurality of light emitting devices 1341, and the driving circuit 1345 is electrically connected to the plurality of light emitting devices 1341 and drives the plurality of light emitting devices 1341 to emit light.
The display panel 130 in the embodiment of the present application sets the transparent substrate 133 through the light emitting surface 1311 of the reflective display module 131, the transparent substrate 133 is provided with a plurality of light emitting devices 1341, the light emitting devices 1341 are driven by the driving circuit 1345 to emit light, the light emitted by the light emitting devices 1341 does not need to pass through the light guide plate in the process of entering the display module from the light emitting surface 1311 of the reflective display module 131, the light energy loss is small, and therefore the power of the light source module can be reduced, and the energy consumption of the display panel is further reduced.
Moreover, the light emitting device 1341 of the light source module 132 can directly emit light toward the light emitting surface 1311 of the reflective display module 131, so that the light source of the light source module 132 has better directivity, and the problem of backward light transmission of the transparent substrate 133 can be prevented.
Optionally, the light emitting device 1341 is a white light emitting device, that is, the light emitted by the light emitting device 1341 is white light, so that the reflective display module 131 has a better display effect. Specifically, the light emitting device 1341 directly emits white light, or the light emitted by the light emitting device 1341 is light of another color, and a light conversion layer (not shown in the figure) is disposed on the light emitting device 1341 to convert the light emitted by the light emitting device 1341 into white light.
Specific examples thereof include: the light emitted from the light emitting device 1341 is blue light, and the light conversion layer is composed of yellow phosphor or a red and green mixed phosphor conversion material, such as: nitride phosphor (Nitride), sulfide phosphor (sulphoide), fluoride phosphor (fluoride), quantum dots (quantum dots), and the like.
In other embodiments, as shown in fig. 5, the light emitting device 1341a includes a plurality of sub light emitting devices 1346 having different light emitting colors, and light emitted from each sub light emitting device 1346 is mixed into white light. Specific examples thereof include: the light emitting device 1341 includes three sub light emitting devices 1346, light emitted from the three sub light emitting devices 1346 is red, green, and blue, respectively, and light emitted from the three sub light emitting devices 1346 is mixed to form white light. Of course, the number of the sub-light emitting devices 1346 included in the light emitting device 1341a may also be two, four or more, and only the light emitted from the sub-light emitting devices 1346 of the light emitting device 1341a needs to be mixed into white light, which is not limited herein.
Optionally, as shown in fig. 1, the light emitting surface 1311 of the reflective display module 131 is provided with an Optical Clear Adhesive (OCA) layer 1316, and the optical Adhesive layer 1316 and a side surface of the light emitting module 134 departing from the transparent substrate 133 are attached together, so as to connect the light source module 132 and the reflective display module 131 together.
Alternatively, as shown in fig. 2, the display panel 130a further includes a sealant 1317 disposed at the periphery of the reflective display module 131, and the sealant 1317 is connected to the periphery of the light source module 132, so as to connect the light source module 132 and the reflective display module 131 together.
Alternatively, the Light Emitting device 1341 includes one or more of an Organic Light Emitting Diode (OLED), a Mini LED, and a Micro LED. Because the sizes of the organic electroluminescent device, the Mini LED light emitting device and the Micro LED light emitting device are small, the light emitting device 1341 can be prevented from affecting the display effect of the reflective display module 131.
It should be noted that the light emitting device 1341 may only include one of an organic electroluminescent device, a Mini LED light emitting device 1341 and a Micro LED light emitting device 1341, or may simultaneously include two or three of an organic electroluminescent device, a Mini LED light emitting device and a Micro LED light emitting device, and of course, when the light emitting device 1341 only includes one of an organic electroluminescent device, a Mini LED light emitting device and a Micro LED light emitting device, the processing of the light source module 132 is more convenient.
When the light emitting device 1341 is an organic electroluminescent device 1341, as shown in fig. 4, the light emitting device 1341 includes an anode layer 1342, an organic electroluminescent layer 1343 and a cathode layer 1344, wherein the anode layer 1342 is formed on the light emitting surface 1311 of the reflective display module 131, the organic electroluminescent layer 1343 is formed on the anode layer 1342, and the cathode layer 1344 is formed on the organic electroluminescent layer 1343. By directly forming the light emitting device 1341 on the light emitting surface 1311 of the reflective display module 131, the manufacturing process of the display panel 130 can be simplified, the production efficiency of the display panel 130 can be improved, and the overall thickness of the display panel 130 can be reduced.
Specifically, after the reflective display module 131 is manufactured, an anode layer 1342 is formed on the light emitting surface 1311 of the reflective display module 131 through deposition, etching, and the like, and the anode layer 1342 is etched to form a plurality of anodes; thereafter, an organic electroluminescent layer 1343 is formed on the anode layer 1342, and finally, a cathode layer 1344 is formed on the organic electroluminescent layer 1343, the cathode layer 1344 including a plurality of cathodes corresponding to the plurality of anodes one to one. The processes for forming the anode, the organic electroluminescent layer 1343 and the cathode layer 1344 are well known in the art and will not be described herein in detail.
