By analogy, electrochromic layer 14 may also include a third color-changing portion, a fourth color-changing portion, and so on. Electrochromic materials of the respective color-changing portions are different from each other. For example, the conductive layer 132 is electrically connected to the first color changing portion 141. For another example, the conductive layer 132 is electrically connected to the second color changing portion 142. For another example, the conductive layer 132 electrically connects the first color changing portion 141 and the second color changing portion 142.
Because the first color-changing portion 141 is connected with the second color-changing portion 142, no matter the conductive layer 132 is conducted to either the first color-changing portion 141 or the second color-changing portion 142, the first color-changing portion 141 and the second color-changing portion 142 can be connected with the conductive layer 132, and the controller 11 can control the first color-changing portion 141 and the second color-changing portion 142 simultaneously, so that the first color-changing portion 141 and the second color-changing portion 142 are switched between the non-color-developing state and the color-developing state, and the working efficiency of the display panel 1 is improved.
Referring to fig. 1, fig. 2, and fig. 4 together, fig. 4 is a top view of a first insulating layer and an electrochromic layer according to an embodiment of the present disclosure.
In one embodiment, the electrochromic layer 14 includes a first color-changing portion 141 and a second color-changing portion 142 arranged along a direction perpendicular to an arrangement direction of the display screen 12 and the first insulating layer 13, and the first color-changing portion 141 and the second color-changing portion 142 are disposed in an insulating manner; the display panel 1 further includes conductive wires 17, one of the conductive wires 17 electrically connects the first color-changing portion 141 and the conductive layer 132, and the other conductive wire 17 electrically connects the second color-changing portion 142 and the conductive layer 132.
Optionally, the first color-changing portion 141 and the second color-changing portion 142 are disposed at intervals, and the display panel 1 further includes a third insulating layer 143, where the third insulating layer 143 is disposed between the first color-changing portion 141 and the second color-changing portion 142. The number of conductive wires 17 is less than or equal to the number of color-changing portions. One conductive wire 17 electrically connects one color-changing portion with the conductive layer 132, so that the controller 11 can individually control one color-changing portion to switch between a non-color-developing state and a color-developing state through one conductive wire 17.
In this embodiment, the first color-changing portion 141 and the second color-changing portion 142 are connected to different conductive wires 17, so that the controller 11 can control the first color-changing portion 141 and the second color-changing portion 142 separately, thereby providing the electrochromic layer 14 with various display modes and increasing the diversity of display. For example, the first color-changing portion 141 and the second color-changing portion 142 may have different current levels, and the electrochromic material may display different colors, and may have different hues by circuit control, so that the colors are more abundant. For another example, the first color changing portion 141 and the second color changing portion 142 may have the same current. For another example, one of the first color changing portion 141 and the second color changing portion 142 is in a color development state, and the other is in a non-color development state.
Referring to fig. 1, 2, and 4, in one embodiment, a receiving groove 133 is disposed on a side of the first insulating layer 13 facing away from the display surface 121, for receiving at least part of the conductive wire 17, and one end of the receiving groove 133 is connected to the electrochromic layer 14, and the other end is connected to the connection hole 131.
In this embodiment, a receiving groove 133 is formed in a surface of the first insulating layer 13 facing away from the display surface 121. For example, a part of the conductive wire 17 is accommodated in the accommodation groove 133. For another example, all the conductive wires 17 are accommodated in the accommodating groove 133. One end of one accommodation groove 133 is communicated with the first color changing part 141, and the other end is communicated with the connecting hole 131. One end of the other accommodating groove 133 is communicated with the second color changing part 142, and the other end is communicated with the connecting hole 131.
On the other hand, the conductive wires 17 are accommodated in the accommodating grooves 133, so that the protrusion of a part of the electrochromic layer 14 can be avoided, and the electrochromic layer 14 is smoothly arranged on the first insulating layer 13. On the other hand, the accommodating groove 133 is formed first to play a role in positioning and fixing, so that the setting difficulty of the conductive wire 17 can be reduced, the position of the conductive wire 17 can be fixed, and the stability of the display panel 1 can be improved.
Referring to fig. 1, fig. 2, fig. 4, and fig. 5, fig. 5 is a top view of a display panel according to an embodiment of the present application. In one embodiment, the display screen 12 further includes a plurality of pixel units 122 arranged in an array, and at least a portion of the orthographic projection of the conductive wire 17 on the display screen 12 is located in a gap between two adjacent pixel units 122.
For example, a part of the conductive line 17 corresponds to a gap region between two adjacent pixel units 122. For another example, all of the conductive lines 17 correspond to a gap region between two adjacent pixel cells 122. At least part of the conductive lines 17 are arranged in the spaced areas of adjacent pixels of the OLED. This arrangement reduces the chance that the conductive lines 17 will block light from the pixel elements 122. When the display screen 12 is in the bright state, most of the light rays emitted by the pixel units 122, even all of the light rays, can avoid the conductive wires 17 and be emitted outside through the first insulating layer 13, the electrochromic layer 14 and the second insulating layer 15, so that the display effect of the display screen 12 is improved.
In addition, the arrangement can reduce the probability that the conductive wire 17 is developed due to strong light emitted from the side, away from the second insulating layer 15, of the conductive wire 17, that is, the probability that the conductive wire 17 is developed on the display panel 1 is reduced, or the conductive wire 17 is shielded, so that the display effect of the display screen 12 is further improved.
Referring to fig. 1, 2, 4 and 5, in one embodiment, the display screen 12 further includes a black matrix layer 123, the black matrix layer 123 has a plurality of openings for accommodating the pixel units 122, and at least a portion of the orthographic projection of the conductive wires 17 on the display screen 12 is located on the black matrix layer 123.
For example, a part of the conductive lines 17 corresponds to the black matrix layer 123. For another example, all of the conductive lines 17 correspond to the black matrix layer 123. At least part of the conductive lines 17 are arranged at the LCD display 12 corresponding to the black matrix. This arrangement prevents the conductive lines 17 from blocking light emitted from the pixel units 122. When the display screen 12 is in the bright state, the light emitted by the pixel unit 122 can avoid the conductive wire 17 and be emitted outside through the first insulating layer 13, the electrochromic layer 14 and the second insulating layer 15, so as to improve the display effect of the display screen 12.
In addition, the arrangement can prevent the conductive wire 17 from being developed due to strong light emitted from the side of the conductive wire 17 away from the second insulating layer 15, that is, prevent the conductive wire 17 from being developed on the display panel 1, or shield the conductive wire 17, so as to further improve the display effect of the display screen 12.
Referring to fig. 1-6 together, fig. 6 is a schematic cross-sectional view of a display screen according to an embodiment of the disclosure. In one embodiment, the display screen 12 further includes a wiring layer 124 and a light shielding layer 125, the light shielding layer 125 is closer to the electrochromic layer 14 than the wiring layer 124, and the light shielding layer 125 covers the wiring layer 124 for shielding the wiring layer 124.
The trace layer 124 includes scan lines, data lines, etc., wires that carry signal elements. The trace layer 124 is electrically connected to the pixel unit 122, and is used for controlling the pixel unit 122 to emit light. The wires of the trace layer 124 are typically made of a metallic material. The shading layer 125 is arranged on the wiring layer 124, so that the corresponding area of the wiring layer 124 of the display screen 12 is darker when the display screen 12 is in a bright screen state, reflection of the wiring layer 124 is avoided, the pixel effect of the display screen 12 is improved, the corresponding area of the wiring layer 124 of the display screen 12 is darker when the display screen 12 is in a screen-extinguishing state, reflection of the wiring layer 124 is avoided, dark brightness of the display screen 12 can be reduced, contrast ratio between the display screen 12 and the electrochromic layer 14 is improved, the display panel 1 presents more colorful modes when the screen is in the screen-extinguishing state, and different requirements are met.
