Definitions
- Embodiments of the present invention relate to a display panel motherboard and a method of fabricating the same. Background technique
- display devices are widely used in modern digital information devices due to their small size, low power consumption, no radiation, and high resolution.
- the display device includes a display panel formed by cutting two display panel mother boards (e.g., an array substrate mother board and a color filter substrate mother board) after the box is cut.
- Display panel The motherboard is provided with a cutting line, and the cutting line is located in the pre-cut area on the display panel motherboard.
- the cutting line divides the display panel motherboard into a plurality of display panels, and the display panel is located at the display panel area of the display panel motherboard. After the cutting of the display panel motherboard is completed according to the cutting line, a display panel area i or a corresponding display panel.
- the general steps of forming the display panel mother board include: performing large-area film formation, exposure, and large-area etching on the glass substrate to form respective layer structures of the display panel mother board.
- other layers are typically etched to form patterns (eg, gate lines, data lines, transparent electrodes), and due to the electrically insulating layers of the layers, such as gate insulating layers,
- the deposition of an insulating layer or the like of the passivation layer may cause different stresses, causing shrinkage or expansion of the glass substrate.
- the passivation layer and the gate insulating layer are large-area film-forming, and finally only a small number of via holes are formed. Therefore, after the etching, the stress cannot be sufficiently released. Therefore, after the process of forming the passivation layer and the gate insulating layer, the glass substrate is affected by the internal stress of the large-area electrical insulating layer such as the passivation layer and the gate insulating layer, and the tendency of retraction or expansion is unstable. It has a great influence on the subsequent process, and in particular, it is easy to cause a pattern shift of the film layer formed above these electrical insulating layers. Summary of the invention
- Embodiments of the present invention provide a display panel motherboard that can improve pattern shift and a method of fabricating the same.
- a method for fabricating a display panel motherboard includes: a display panel region spaced apart from each other, and adjacent to the display panel region The pre-cutting area, the preparation method comprises:
- An electrically insulating layer disposed at least partially in the pre-cut region is removed.
- the electrically insulating layer of the pre-cut region is removed by a patterning process.
- the electrically insulating layers of the pre-cut regions are all removed.
- the method further includes: in the patterning process, patterning the electrically insulating layer of the pre-cut region with a jagged mask at the edge to make the remaining pre-cut
- the slope of the electrical insulation layer of the area forms a slope angle.
- a display panel motherboard including: a display panel area spaced apart from each other, and a pre-cut area adjacent to the display panel area, wherein at least a portion of the display panel motherboard is disposed An electrical insulating layer in the pre-cut region is removed.
- the electrically insulating layers of the pre-cut regions are all removed.
- the remaining electrical insulating layer is provided with a slope angle at the edge.
- the angle of the slope angle is between 30 degrees and 70 degrees.
- the electrically insulating layer is any one or more of a passivation layer, a gate insulating layer, and an etch barrier.
- FIG. 1 is a schematic view of a display substrate mother board according to Embodiment 1 of the present invention.
- FIG. 2a and 2b are schematic views showing a method of preparing a display substrate according to Embodiment 2 of the present invention
- Fig. 3 is a partial structural view showing a zigzag mask in a method of manufacturing a display substrate according to Embodiment 2 of the present invention.
- the patterns and patterns referred to in the embodiments of the present invention refer to various structures formed by a patterning process; the patterning process referred to in the present invention includes photoresist coating, masking, exposure, development, Part or all of the etching, photoresist stripping, etc., the photoresist is exemplified by a positive photoresist, but this is not a limitation of the present invention.
- the embodiment provides a display panel motherboard including: a display panel area Q1 spaced apart from each other, and a pre-cut area Q2 adjacent to the display panel area Q1.
- the display panel area Q1 corresponds to the position of the display panel
- the pre-cut area Q2 corresponds to the position of the cutting line.
- the electrically insulating layer 102 at least partially disposed in the pre-cut region Q2 is removed.
- the internal stress of the electrical insulating layer 102 is well released, so that it is good.
- the influence of the large stress inside the electrical insulating layer 102 on other film layers disposed above or below the electrical insulating layer 102 is avoided, and the other patterns may be biased on the display panel mother board due to the large internal stress of the electrical insulating layer 102.
- the phenomenon of shifting is improved.
- the electrical insulating layer 102 of the pre-cut region Q2 is completely removed.
- the internal stress of the electrical insulating layer 102 is released as much as possible while avoiding other film layers deposited over the electrically insulating layer 102 from being affected, in particular, care should be taken to avoid electrical wiring due to the pre-cut region Q2.
- the influence of the step difference generated by the removal of the insulating layer 102 on the subsequent process for example, when the rubbing orientation is formed after the formation of the alignment film, due to the existence of the step difference, undulation will occur during the rubbing, which in turn will have a corresponding influence on the orientation (friction orientation)
- the direction is the direction of the arrow shown in Figure 1.
- a certain slope angle is retained at the edge of the remaining electrical insulating layer 102, so that the slope of the portion of the electrically insulating layer 102 where the pre-cut region Q2 is removed is more gentle, thereby reducing the film.
- the undulation of the material orientation However, the electricity in the display panel area Q1
- the slope angle at the via remains at the insulating layer 102, which mitigates the effects of the removal of the electrically insulating layer 102 at the pre-cut region Q2.
- the slope angle is preferably between 30 degrees and 70 degrees, and can be specifically set according to specific conditions.
- the electrical insulating layer 102 is, for example, any one or more of a passivation layer, a gate insulating layer, and an etch barrier layer.
- the passivation layer is provided between the source/drain electrode layer of the thin film transistor and the pixel electrode layer.
- the pixel electrode may be connected to the drain through a contact via penetrating through the passivation layer.
- a gate insulating layer is used to separate the gate layer from the active region.
- the source and drain electrodes are connected to the active region through contact vias through the etch barrier. Usually, since only a small number of via holes are provided on these electrical insulating layers, the internal stress cannot be released well.
- the internal stress can be well released, and the problem of offsetting of other patterns due to excessive internal stress of the layers of the electrical insulating layer can be improved.
- Other electrical insulating layers provided in the pre-cut region Q2 in the display panel mother board can also be removed.
- the electrical insulating layer disposed at least partially in the pre-cut region is removed, the internal stress of the electrical insulating layer can be well released, so that the inside of the electrical insulating layer can be well avoided.
- the influence of the larger stress on other film layers disposed above or below the electrical insulating layer can further improve the phenomenon that other patterns are shifted due to the large internal stress of the electrical insulating layer on the display panel mother board.
- the embodiment provides a method for preparing a display panel motherboard.
- the display panel motherboard includes: a plurality of display panel regions spaced apart from each other, and a pre-adjacent to the plurality of display panel regions. Cutting the area, the method comprising the steps of:
- An electrical insulating layer film 102 is formed on the substrate 101, and a photoresist 103 is coated on the electrically insulating layer film 102 to expose and develop the photoresist.
- the photoresist corresponding to the photoresist 105 in contact with the via region 104 and the electrically insulating layer in the corresponding pre-cut region 105 is removed, as shown in Figure 2a.
- the step of forming the contact via may be synchronized with the above steps or may be performed separately.
- the contact vias of the respective layers may be separately formed, and the electrically insulating layer 102 of the pre-cut regions may be uniformly removed.
- a pattern including the electrically insulating layer 102 is formed on the substrate by a patterning process, and the electrically insulating layer 102 at least partially disposed in the pre-cut region is removed.
- the area where the electrical insulation layer is removed is shown as 107 in Figure 2b.
- Corresponding contact vias 106 are shown in Figure 2b.
- the internal stress of the electrical insulating layer 102 can be well released, and the electrical insulating layer 102 can be well avoided.
- the influence of the internal large stress on other film layers disposed above or below the electrical insulating layer 102 can further improve the phenomenon that other patterns are shifted due to the large internal stress of the electrical insulating layer on the display panel mother board.
- the electrically insulating layer 102 of the pre-cut region is completely removed.
- the pattern including the electrically insulating layer 102 formed on the substrate by a patterning process may employ a masking plate 108 provided with a zigzag at the edge. Since the mask is used, a certain slope angle is maintained at the edge of the electrical insulating layer 102, thereby avoiding the influence of the step caused by the removal of the electrical insulating layer 102 of the pre-cut region on the subsequent process.
- a layer of photoresist is formed on the substrate on which the electrically insulating film is formed, and a zigzag mask is used for exposure. This creates a slope angle on the photoresist because the light is diffracted at the sharp corners of the sawtooth mask.
- etching for example, dry etching
- the electrically insulating layer disposed under the photoresist will replicate the slope angle of the photoresist, thereby forming at the edge of the electrically insulating layer 102 at the pre-cut region Q2.
- a gentler slope angle In this way, the influence on the subsequent rubbing alignment process can be reduced, and the stress of the passivation layer can be effectively released.
- the position of the sawtooth mask in the electrical insulating layer 102 corresponding to the pre-cut area may be changed, and the mask pattern of other areas may be set as needed to form other patterns on the display substrate, that is, sawtooth masking. There is no conflict between the diaphragm and the formation of other area graphics, and the position is not limited.
