Abstract: A button structure includes a switch, a shell, an elastic member, a button and at least one adjustable limiting member. The elastic member includes a fixing portion, a compressive portion and an elastic portion. The fixing portion is connected to the shell. The compressive portion is configured to abut against the switch. The elastic portion is connected between the fixing portion and the compressive portion. The elastic portion is suitable for deformation. The button is connected to the compressive portion, and the compressive portion is located between the button and the switch. The adjustable limiting member is disposed on the button, and is configured to abut against the elastic portion. The adjustable limiting member adjustably protrudes for a length toward the elastic portion relative to the button.

Abstract: A display panel is provided. The display panel includes a first substrate; a second substrate; a shielding layer; a first color filter; and a spacer. The second substrate is disposed opposite the first substrate. The shielding layer is disposed over the second substrate, wherein the shielding layer includes two shielding pattern rows projected onto the second substrate. The first color filter is disposed over the second substrate and the shielding layer. The spacer is disposed over the first color filter, wherein the spacer includes a spacer pattern projected onto the second substrate, and the spacer pattern overlaps one of the two shielding pattern rows, and the one of the two shielding pattern rows includes an expansion portion, wherein the expansion portion has an edge and at least part of the edge is curved.

Abstract: A display panel is provided. The display panel includes a first substrate; a second substrate; a shielding layer including two shielding pattern rows projected onto the second substrate; a first color filter and a spacer, wherein the spacer includes a spacer pattern projected onto the second substrate, and the spacer pattern overlaps one of the two shielding pattern rows. The first color filter includes a first side projected onto the second substrate. The first side includes a first portion located between the two shielding pattern rows and a second portion overlapped one of the two shielding pattern rows. A shortest distance between an extension line of the first portion and a center of the spacer pattern is a first distance, and a shortest distance between the second portion and the center of the spacer pattern is a second distance. The first distance is shorter than the second distance.

Abstract: A method of preparing a composite material includes the steps of: (a) dispersing graphene material and graphene oxide material in a solution, where the weight ratio of the graphene material to the graphene oxide material is between 0.2-1; and (b) after step (a), stirring the solution at a first temperature.

Abstract: A display panel includes a first substrate, a second substrate and a display medium. At least one spacer is formed on the top surface of the first substrate and is disposed between the first substrate and the second substrate. An alignment film is formed on the first substrate and covers the spacer. The spacer has a first width and a second width in a direction perpendicular to a normal vector of the first substrate. The location of the second width is nearer to the first substrate than that of the first width. The second width is smaller than the first width. The alignment film has a first thickness at the location of the spacer having the first width and has a second thickness at the location of the spacer having the second width. The second thickness is greater than the first thickness.
