Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to an image processing device, a driving device, and a display device for a display panel. Background Art

[0002] Organic Light Emitting Diode (OLED) display technology is considered the most promising new display technology for the next generation. Compared with liquid crystal display technology, OLED display technology has advantages such as low energy consumption, low cost, self-luminescence, wide viewing angle, and fast response speed.

[0003] In the traditional OLED display panel manufacturing process, pixel patterning is typically achieved through a fine metal mask (FMM). FMM technology is mature and has extensive mass production experience. However, FMM technology also has issues such as limited precision and high cost. Fine metal mask-free technology eliminates the limitations of traditional OLED processes on display size, resolution, and other screen performance, offering the advantages of high performance, full-area sizing, and agile delivery.

[0139] In one example, the isolation structure 12 includes an isolation portion 122 and a barrier portion 121 stacked in a direction away from the array substrate 11 (i.e., the Z direction). The width of the barrier portion 121 is greater than the width of the isolation portion 122. As a result, the ends of the barrier portion 121 protrude relative to the side surfaces of the isolation portion 122. This shape of the isolation structure 12 is also referred to as an overhang. The isolation portion 122 and the barrier portion 121 are made of different materials, and the etching rate of the barrier portion 121 is lower than that of the isolation portion 122.

When the barrier portion 121 has a multi-layer structure, one layer of the barrier portion 121 may be made of at least one of titanium, titanium nitride, molybdenum, tungsten, a molybdenum-tungsten alloy, or a molybdenum-niobium alloy, and another layer of the barrier portion 121 may be made of a conductive oxide or an inorganic insulating material, such as indium tin oxide (ITO) or indium zinc oxide (IZO).

[0140] Figure 15 is an enlarged cross-sectional view of the display panel. In some embodiments, reference Figure 15 The isolation structure 12 may further include a base portion 123 located on a side of the isolation portion 122 close to the array substrate 11. The base portion 123 protrudes relative to the isolation portion 122 in a direction toward the isolation opening 12a.

The material of the base portion 123 may include at least one of molybdenum (Mo), titanium (Ti), titanium nitride (TiN), molybdenum-tungsten alloy (MoW), or molybdenum-niobium alloy (MoNb).

[0141] In one embodiment, the display panel 100 may further include a pixel defining layer 17, with the isolation structure 12 disposed on the pixel defining layer 17. Pixel openings communicating with the isolation openings 12a are disposed on the pixel defining layer 17. Specifically, the pixel defining layer 17 includes a first pixel opening communicating with the first isolation opening 12a1, a second pixel opening communicating with the second isolation opening 12a2, and a third pixel opening communicating with the third isolation opening 12a3. The orthographic projections of the first, second, and third pixel openings on the array substrate 11 may be the same or different in area. The shapes of the pixel openings and the orthographic projections of the corresponding isolation openings 12a on the array substrate 11 may be the same or different. Generally speaking, the orthographic projection area of ​​the isolation opening 12a on the array substrate 11 is larger than the orthographic projection area of ​​the pixel opening communicating with the isolation opening 12a. The orthographic projections of the pixel openings of the light-emitting devices 13 on the array substrate 11 overlap with the orthographic projections of the isolation openings 12a on the array substrate 11. The pixel defining layer 17 is made of an inorganic material. For example, the pixel defining layer 17 is formed using at least one inorganic insulating material selected from silicon nitride (SiNx), silicon oxide (SiOx), and silicon oxynitride (SiON).

[0142] In one embodiment, the pixel defining layer 17 includes multiple sub-layers, including a first sub-layer and a second sub-layer stacked sequentially in a direction away from the array substrate 11 , that is, the pixel defining layer 17 may adopt a double-layer design.

[0143] For example, the first sublayer has better film-forming properties than the second sublayer. That is, under conditions of equal thickness, the first sublayer can better cover the step structure formed by the first electrode than the second sublayer without generating cracks. Conversely, to achieve the same step coverage effect, the thickness of the first sublayer must be thinner than that of the second sublayer, that is, the thickness requirement for the first sublayer is relatively low, which is conducive to thinning the product. In addition, good film-forming properties are reflected in the good coverage of the formed film, which is more dense and more conducive to isolating water vapor.

[0144] For example, the second sublayer has better etching resistance than the first sublayer. Because the side of the pixel defining layer 17 facing away from the array substrate 11 is subject to etching during the display panel manufacturing process, selecting a material with stronger etching resistance as the second sublayer can improve the etching resistance of the pixel defining layer 17, further improving the reliability of the display panel.

[0145] Exemplarily, the first sub-layer and the second sub-layer are made of different materials. For example, the first sub-layer may be made of silicon nitride, and the second sub-layer may be made of silicon oxide.

[0146] Exemplarily, the thickness of the first sublayer is greater than or equal to 1000 micrometers and less than or equal to 5000 micrometers. For example, the thickness of the first sublayer is 1000 micrometers, 2000 micrometers, 3000 micrometers, 4000 micrometers, 5000 micrometers, etc.

[0147] Exemplarily, the thickness of the second sub-layer is greater than or equal to 500 micrometers and less than or equal to 3000 micrometers. For example, the thickness of the second sub-layer is 500 micrometers, 1000 micrometers, 2000 micrometers, 3000 micrometers, etc.

[0148] In another embodiment, the isolation structure 12 is disposed in the groove of the pixel defining layer 17. Alternatively, the pixel defining layer 17 may not be disposed in the display panel 100, and the isolation structure 12 is disposed on one side of the array substrate 11, and the isolation structure 12 is disposed in contact with one side of the array substrate 11.

[0149] The first light-emitting device 13a, the second light-emitting device 13b, and the third light-emitting device 13c each emit light of a different color. Each of the first light-emitting device 13a, the second light-emitting device 13b, and the third light-emitting device 13c includes a first electrode 131, a light-emitting structure 132, and a second electrode 133, which are stacked in layers. The first electrode 131 is disposed on the array substrate 11. A pixel-defining layer 17 covers the end of the first electrode 131. A pixel-defining layer 17 is provided, through which the first electrode 131 is exposed. The light-emitting structures 132 of the first light-emitting device 13a, the second light-emitting device 13b, and the third light-emitting device 13c cover the sidewalls of the pixel opening of the pixel-defining layer 17 and the side of the pixel-defining layer 17 facing away from the array substrate 11. Each light-emitting structure 132 is located within the pixel opening and in contact with the first electrode 131.

[0150] The second electrodes 133 of the first light-emitting device 13a, the second light-emitting device 13b, and the third light-emitting device 13c respectively cover the corresponding light-emitting structures 132. The second electrode 133 is electrically connected to the isolation structure 12. For example, the second electrode 133 is connected to the isolation portion 122 of the isolation structure 12, and / or the second electrode 133 is connected to the base 123 of the isolation structure 12. Specifically, when the isolation structure 12 includes a three-layer structure of a blocking portion 121, an isolation portion 122, and a base 123, the second electrode 133 may extend to a side surface of the base 123 facing away from the array substrate 11 to connect to the base 123. In this case, the second electrode 133 may be connected to the isolation portion 122 or not.

[0152] The first electrode 131 may include a multilayer structure. For example, the first electrode 131 may include a reflective layer and a pair of conductive oxide layers covering the upper and lower surfaces of the reflective layer, respectively. The reflective layer may be formed using, for example, a metal material with excellent light reflectivity, such as silver. Each conductive oxide layer may be formed using, for example, a transparent conductive oxide such as ITO (Indium Tin Oxide), IZO (Indium Zinc Oxide), or IGZO (Indium Gallium Zinc Oxide). The second electrode 133 may be formed using, for example, a metal material such as an alloy of magnesium and silver (MgAg).
