Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be noted that the following examples are only illustrative of the present invention, and do not limit the scope of the present invention. Likewise, the following examples are only some but not all examples of the present invention, and all other examples obtained by those skilled in the art without any inventive step are within the scope of the present invention.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.

A cellular phone is an electronic device equipped with a cellular communication module.
It should be noted that the display screen of the electronic device in the embodiment of the present application may have a structure with four curved surfaces, three curved surfaces, two curved surfaces, one curved surface, or no curved surface. The edge of the display screen is a non-display area, and if the width of the non-display area is large, user experience can be influenced. What this application mainly solved is the great problem of non-display area width to realize the effect of narrow frame. The electronic equipment can be designed to be a comprehensive screen further.
Referring to fig. 1 and fig. 2 together, fig. 1 is a schematic axial side structure diagram of an electronic device in an embodiment of the present application, and fig. 2 is an exploded view of the electronic device in the embodiment of fig. 1. It should be noted that the electronic device in the present application may include an electronic device having a curved display screen or a non-curved display screen structure, such as a mobile phone, a tablet computer, a notebook computer, and a wearable device. The electronic device includes, but is not limited to, the following structures: a display screen assembly 10 and a housing 20. The display screen assembly 10 is embedded in the housing 20 for displaying information.
In one embodiment, referring to fig. 2, the display panel assembly 10 may include a display panel cover 100 and a display module 200. The display screen cover 100 is fastened to the housing 20 and encloses a receiving space 101. The display module 200 is disposed in the accommodating space 101 and attached to the surface of the display cover plate 100 for displaying information.
Specifically, the display screen cover plate 100 may be made of glass for protecting the display module 200, so that the display module 200 is not damaged. In an embodiment, the display module 200 may be a flexible display such as an OLED (Organic Light-Emitting Diode) flexible display.
In an embodiment, please refer to fig. 3 and fig. 4 in combination, wherein fig. 3 is a schematic diagram of a distribution of a display module 200 according to an embodiment of the present disclosure, and fig. 4 is a schematic diagram of a portion of a region a in fig. 3. The display module 200 may generally include a display region 210 and a non-display region 220 (e.g., a first non-display region 221, a second non-display region 222, a third non-display region 223, a fourth non-display region 224, etc.). Specifically, the non-display area 220 may be disposed around the edge of the display area 210. The display area 210 and the non-display area 220 are connected as one body. It is understood that the display area 210 of the display module 200 can be used for displaying messages, and the non-display area 220 of the display module 200 generally has no display function. The width of the non-display area 220 is related to whether the electronic device can achieve the ultra-narrow bezel effect.
It should be noted that the terms "first", "second" and "third" in the present invention are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.
For the above and below-described names, "first non-display region", "second non-display region", "third non-display region", "fourth non-display region", and "non-display region" may be mutually converted, for example, "first non-display region" may also be referred to as "second non-display region", and may also be referred to as "non-display region".
Referring to fig. 3, in an embodiment, the non-display area 220 may include a first non-display area 221, a second non-display area 222, a third non-display area 223, and a fourth non-display area 224. The first non-display area 221, the second non-display area 222, the third non-display area 223, and the fourth non-display area 224 are sequentially connected end to end. The first non-display area 221, the second non-display area 222, the third non-display area 223, and the fourth non-display area 224 are surrounded around the display area 210. In one embodiment, the first non-display region 221, the second non-display region 222, the third non-display region 223 and the fourth non-display region 224 form a rectangular ring structure.
Specifically, the display module 200 is disposed around the display region 210, i.e., in the non-display region 220, the scan driving circuit region 230, the cathode trace circuit region 240, and the electrostatic discharge circuit region 250.
A scan driving circuit is disposed in the scan driving circuit region 230 for driving the scan lines. The scan driving circuit region 230 is generally disposed around the display region 210 and close to the display region 210, so as to improve the integration of the display module 200. Due to the packaging requirements of the display module 200, the outer periphery of the packaged display module 200 is usually spaced from the scan driving circuit region 230. For example, as shown in fig. 3, the scan driving circuit regions 230 may be disposed on opposite sides of the display region 210, for example, in the first non-display region 221 and the third non-display region 223.
A cathode trace circuit is disposed in the cathode trace circuit area 240 for source voltage traces. The cathode trace circuit area 240 is generally disposed around the display area 210 and close to the display area 210, so as to improve the integration of the display module 200. The cathode trace circuit area 240 is disposed around the scan driving circuit area 230. In one embodiment, as shown in fig. 3, the cathode trace circuit area 240 may be disposed in the display area 210, such as the first non-display area 221 and the third non-display area 223. In one embodiment, the cathode trace circuit region 240 may be disposed on only one side of the display region 210, such as the first non-display region 221. The scan driving circuit region 230 is located between the display region 210 and the cathode trace circuit region 240.
In one embodiment, in the above circuits, the cathode trace circuit in the cathode trace circuit area 240 can be electrically connected to the scan driving circuit in the scan driving circuit area 230.
Referring to fig. 3 and 4, the esd circuits in the esd circuit area 250 are designed to prevent crosstalk when the data line current is too large, and the too large circuits are unloaded to the other metal layer grounding traces. Semiconductor components are commonly used to implement functions. The esd circuits in the esd circuit region 250 are used to protect the data line circuits. The esd circuit region 250 is generally disposed around the display region 210 and close to the display region 210 to improve the integration of the display module 200. In one embodiment, as shown in fig. 3, the esd circuit region 250 may be disposed in the non-display region 220, such as the second non-display region 222.
It is to be understood that the scan driving circuit, the cathode trace circuit, the electrostatic discharge circuit, and the data line circuit described above can be connected by wires according to known connection methods understood by those skilled in the art.
Referring to fig. 3, the scan driving circuit region 230 and the cathode trace circuit region 240 in the first non-display region 221 and the third non-display region 223 extend to one side of the second non-display region 222. That is, the scan driving circuit region 230 and the cathode trace circuit region 240 are disposed to extend toward the side of the electrostatic discharge circuit region 250, so that the electrostatic discharge circuit region 250 is located between the cathode trace circuit regions 240.
In one embodiment, the scan driving circuit region 230 is disposed at one side of the display region 210, for example, the first non-display region 221. Referring to fig. 4, the width B of the non-display area 220 is substantially composed of three portions. One of the portions is a first width between the outer periphery of the display region 210 and the scan driving circuit region 230, the other portion is a second width between the scan driving circuit region 230 and the cathode wiring circuit region 240, and the remaining portion is a third width from the cathode wiring circuit region 240 to the outer periphery of the first non-display region 221. The width B of the non-display area 220 is substantially formed by the superposition of the first width, the second width and the third width, which is generally more than 1 mm.
Referring to fig. 4, the width of the portion of the esd circuit region 250 on the side of the first non-display region 221, which exceeds the outer periphery of the display region 210, is C. It can be understood by those skilled in the art that the esd circuit region 250 reduces the portion of the end portion of the first non-display region 221 beyond the outer periphery of the display region 210, i.e. the width C is reduced, the first width between the outer periphery of the display region 210 and the scan driving circuit region 230 can be reduced, the width of the non-display region 220 can be further reduced, and the integration of the display module 200 can be further improved, so as to achieve the effect of ultra-narrow bezel.
Referring to fig. 5, a schematic structural diagram of an electrostatic discharge unit according to an embodiment of the present application is disclosed. The electrostatic discharge cells constitute the electrostatic discharge circuit in the electrostatic discharge circuit region 250 shown in fig. 4.
The electrostatic discharge unit may include a data line 260, a first ground trace 270, and a second ground trace 280. The first ground trace 270 and the second ground trace 280 are electrically connected to the data line 260, respectively. At least one insulating filling layer is disposed between the first ground trace 270 and the second ground trace 280 and the data line 260, respectively. The insulating filling layer has a plurality of via holes for the first ground trace 270 and the second ground trace 280 to be connected to the via holes of the data lines 260, respectively.
Specifically, a first thin film transistor 291 and a second thin film transistor 292 are disposed between the first ground trace 270 and the data line 260. The drain of the first thin film transistor 291 is electrically connected to the first ground trace 270, the source and the gate of the first thin film transistor 291 are electrically connected to the drain of the second thin film transistor 292, and the source and the gate of the second thin film transistor 292 are electrically connected to the data line 260, so that the first ground trace 270 removes a large current on the data line 260, and the data line 260 is protected.
A third thin film transistor 293 and a fourth thin film transistor 294 are disposed between the second ground trace 280 and the data line 260. The drain of the fourth thin film transistor 294 is electrically connected to the second ground trace 280, the source and the gate of the fourth thin film transistor 294 are electrically connected to the drain of the third thin film transistor 293, respectively, and the source and the gate of the third thin film transistor 293 are electrically connected to the data line 260, respectively, so that the second ground trace 280 removes a large current on the data line 260, thereby protecting the data line 260.
It is understood that the electrostatic discharge circuit in the electrostatic discharge circuit region 250 shown in the embodiment of fig. 4 and 5 uses the first ground trace 270, the second ground trace 280 and the thin film transistors (e.g., the first thin film transistor 291, the second thin film transistor 292, the third thin film transistor 293 and the fourth thin film transistor 294) to remove the large current on the data line 260, and shunt the large current to the first ground trace 270 and the second ground trace 280 to protect the data line 260. However, the electrostatic discharge circuit is designed such that the width C of the electrostatic discharge circuit region 250 at the portion of the end of the first non-display region 221 beyond the outer periphery of the display region 210 is not sufficiently smaller, so that the effect of the narrow bezel is not sufficiently better.
Referring to fig. 6, a schematic structural diagram of an electrostatic discharge unit in another embodiment of the present application is disclosed. The electrostatic discharge cell may be used in place of the electrostatic discharge cell shown in fig. 4 and 5, and in the electrostatic discharge circuit described above. The esd cell may include a data line 260, a first ground trace 270, and a fifth tft 295. At least one insulating filling layer is disposed between the first ground trace 270 and the data line 260. The insulating filling layer has a plurality of vias for connecting the first ground trace 270 and the vias of the data line 260.
The source and the gate of the fifth tft 295 are connected to the data line 260, and the drain of the fifth tft 295 is connected to the first ground trace 270.
For the names of the above and the following, the "first thin film transistor", "second thin film transistor", "third thin film transistor", "fourth thin film transistor", "fifth thin film transistor", and "thin film transistor" may be interchanged, for example, the "first thin film transistor" may also be referred to as the "second thin film transistor" and may also be referred to as the "thin film transistor".
In use, when no electrostatic discharge is generated between the data line 260 and the gate of the fifth thin film transistor 295, the fifth thin film transistor 295 is in an off state; when the static electricity is discharged between the data line 260 and the gate of the fifth tft 295, the gate of the fifth tft 295 can collect the generated charges, so that the originally turned-off fifth tft 295 is turned on, thereby discharging the accumulated charges and reducing the voltage difference, thereby achieving the effect of protecting the display module 200 from the static electricity discharge.
Referring to fig. 5 and 6 together, the circuit in the esd cell shown in fig. 5 uses a plurality of tfts (e.g., a first tft 291, a second tft 292, a third tft 293, and a fourth tft 294) and two ground traces (e.g., a first ground trace 270 and a second ground trace 280). While the circuit in the esd cell shown in fig. 6 uses 1 tft (e.g., the fifth tft 295) and one ground trace (e.g., the first ground trace 270), it can be seen by comparison that the circuit in the esd cell shown in fig. 6 is simplified, and when the esd cell shown in fig. 6 is used in an esd circuit, an ultra-narrow frame can be achieved.
Referring to fig. 7 and 8, fig. 7 is a schematic view illustrating a distribution of regions of a display module 200 according to an embodiment of the disclosure, and fig. 8 is a partially enlarged view of a region D in fig. 7. The display module 200 shown in the dotted line in fig. 7 uses the outline of the esd cell shown in fig. 5, and the display module 200 shown in the solid line uses the outline of the esd cell shown in fig. 6. In FIG. 8, the dotted line portion is a schematic diagram showing the module 200 using the ESD cells shown in FIG. 5, and the solid line portion is a schematic diagram showing the module 200 using the ESD cells shown in FIG. 6.
