Abstract
Official abstract text for this publication.
A display panel includes a first substrate, a second substrate, and a liquid crystal layer between the first substrate and the second substrate. A volume-variable structure is arranged between the first substrate and the second substrate. The volume-variable structure effectively reduces the requirement on the deformation capacity of the spacer due to the liquid crystal margin, which is favorable for improving the surface strength of the display panel. The display panel can be used in a display device.
First claim
Opening claim text (preview).
The invention claimed is: 1. A display panel comprising a first substrate, a second substrate, a liquid crystal layer between the first substrate and the second substrate, and a sealant structure for sealing the liquid crystal layer between the first substrate and the second substrate, wherein a volume-variable structure is arranged between the first substrate and the second substrate, and the volume-variable structure is arranged on inner side of the sealant structure and around the liquid crystal layer, wherein the volume-variable structure comprises a plurality of volume-variable microcapsules, each of the microcapsules comprising a housing and a filling within the housing, wherein the filling is at least one of a gas and a liquid, wherein the gas is at least one of an inert gas, nitrogen, and carbon dioxide. 2. The display panel of claim 1 , wherein the material of the housing is at least one of a thermoplastic polyurethane elastomer, a natural latex, and a natural rubber. 3. The display panel of claim 1 , wherein the microcapsules are fixed on at least one of the first substrate, the second substrate, and the sealant structure. 4. The display panel of claim 1 , wherein the microcapsules are spheres, and wherein microcapsules have a diameter of 0.1 μm-10 μm. 5. The display panel of claim 1 , wherein a spacer is arranged between the first substrate and the second substrate. 6. A display device comprising a display panel, said display panel comprising a first substrate, a second substrate, a liquid crystal layer between the first substrate and the second substrate, and a sealant structure for sealing the liquid crystal layer between the first substrate and the second substrate, wherein a volume-variable structure is arranged between the first substrate and the second substrate, and the volume-variable structure is arranged on inner side of the sealant structure and around the liquid crystal layer, wherein the volume-variable structure comprises a plurality of volume-variable microcapsules, each of the microcapsules comprising a housing and a filling within the housing, wherein the filling is at least one of a gas and a liquid, wherein the gas is at least one of an inert gas, nitrogen, and carbon dioxide. 7. The display panel of claim 2 , wherein a spacer is arranged between the first substrate and the second substrate. 8. The display panel of claim 1 , wherein a spacer is arranged between the first substrate and the second substrate. 9. The display device of claim 6 , wherein the material of the housing is at least one of a thermoplastic polyurethane elastomer, a natural latex, and a natural rubber. 10. The display device of claim 6 , wherein the microcapsules are fixed on at least one of the first substrate, the second substrate, and the sealant structure. 11. The display device of claim 6 , wherein the microcapsules are spheres, and wherein microcapsules have a diameter of 0.1 μm-10 μm.
