An example electronic display system including a housing with a recess, a top side, and a bottom side opposite the top side and a kickstand having a first end and a second end opposite the first end, the first end being rotatably coupled to the housing proximate the bottom side, and the second end being rotationally biased away from the housing. A variable friction assembly is coupled to the first end. The kickstand has a first position in which the second end is received within the recess, and a second position in which the second end is substantially rotatably separated from the recess. Further, the variable friction assembly applies a first friction load to the first end when the kickstand is the first position, and a second friction load when the kickstand is in the second position, wherein the first friction load is greater than the second friction load.

1. An electronic display system, comprising: a housing having a top side and a bottom side opposite the top side;a kickstand having an elongate member further including a first end and a second end opposite the first end, the first end being rotatably coupled to the housing proximate the bottom side
1. An electronic display system, comprising: a housing having a top side and a bottom side opposite the top side;a kickstand having an elongate member further including a first end and a second end opposite the first end, the first end being rotatably coupled to the housing proximate the bottom side thus forming an angle of rotation between the elongate member and the housing, and the second end being rotationally biased away from the housing; anda variable friction assembly to apply a variable level of friction to the first end to resist rotation of the kickstand about the first end; anda release assembly including an actuating member and a rocker arm, wherein the release assembly is to actuate the kickstand via the rocker arm in response to a depression of the actuating member;wherein the elongate member of the kickstand is rotatable from a first position in which the angle of rotation is approximately zero, to a second position in which the angle of rotation is greater than ninety degrees; andwherein the variable friction assembly is to apply an increasing level of friction to the first end as the angle of rotation decreases from the second position to the first position. 2. The electronic display system of claim 1, wherein the second end of the kickstand is rotationally biased with a variable torque assembly coupled to the first end to apply an increasing level of torque to the first end as the angle of rotation decreases from the second position to the first position. 3. The electronic display system of claim 2, wherein the increasing level of torque opposes the increasing level of friction about the first end. 4. The electronic display system of claim 2, wherein the first end of the kickstand is coupled to the housing with a hinge, the hinge further comprising a shaft. 5. The electronic display system of claim 4, wherein the variable torque assembly comprises a torsional spring; and wherein the variable friction assembly comprises a pair of corkscrew-style cams. 6. The electronic display of claim 5, wherein the torsional spring has a first end and a second end, the first end being rotationally fixed to the shaft and the second end being coupled to the housing; and wherein the first of the corkscrew-style cams is rotationally fixed to the shaft, and a second of the corkscrew-style cams is rotationally fixed to the housing. 7. The electronic display system of claim 6, wherein the first of the corkscrew-style cams includes a first helical surface; wherein the second of the corkscrew-style cars includes a second helical surface; and wherein the first and second helical surfaces engage one another. 8. The electronic display system of claim 7, wherein rotation of the second corkscrew-style cam relative to the first corkscrew-style cam causes the first and second helical surfaces to slidingly engage, and adjusts an axial length of the variable friction assembly. 9. The electronic display system of claim 8, wherein the variable friction assembly further comprises a friction production section, the friction production section further comprising: a rotating cam rotatably fixed to the shaft and having a first contact surface; and a fixed washer cam fixed relative to the housing and having a second contact surface: wherein engagement between the first and second contact surfaces resists rotation of the shaft. 10. An electronic display system, comprising: a housing having a recess, a top side, and a bottom side opposite the top side;a kickstand having a first end and a second end opposite the first end, the first end being rotatably coupled to the housing proximate the bottom side, and the second end being rotationally biased away from the housing;a variable friction assembly coupled to the first end; anda release assembly including an actuating member and a rocker arm, wherein the release assembly is to actuate the kickstand via the rocker arm in response to a depression of the actuating member;wherein the kickstand has a first position in which the second end is received within the recess, and a second position in which the second end is substantially rotatably separated from the recess;wherein the variable friction assembly is to apply a first friction load to the first end when the kickstand is the first position, wherein the variable friction assembly is to apply a second friction load when the kickstand is in the second position; andwherein the first friction load is greater than the second friction load. 11. The electronic display system of claim 10, further comprising: a variable torque assembly coupled to the first end; wherein the variable torque assembly is to apply a first torque to the first end when the second end is the first position; wherein the variable torque assembly is to apply a second toque to the first end when the second end is in the second position; and wherein the first torque is greater than the second torque. 12. The electronic display system of claim 10, further comprising: a magnet disposed within the recess; and a metallic surface disposed on the second end of the kickstand; wherein the metallic surface is secured to the magnet when the kickstand is in the first position. 13. The electronic display system of claim 10, wherein the kickstand is angularly shifted over ninety degrees between the first position and the second position. 14. A electronic display system, comprising: a housing having a top side and a bottom side opposite the top side;a kickstand having a first end and a second end opposite the first end, the first end being rotatably coupled to the housing proximate the bottom side with a hinge further including a shaft, and the second end being rotationally biased away from the housing;a variable friction assembly comprising a pair of corkscrew-style washers to apply a variable level of friction to the first end to resist rotation of the kickstand about the first end, based on the relative position of the second end and the housing; anda variable torque assembly further comprising a torsional spring to rotationally bias the second end of the kickstand and to apply a variable level of torque to the first end opposing the variable level of friction; anda release assembly including an actuating member and a rocker arm, wherein the release assembly is to actuate the kickstand via the rocker arm in response to a depression of the actuating member;wherein the variable torque assembly applies an increasing torque load to the shaft as the second end approaches the housing, andwherein the variable friction assembly applies an increasing friction load to the shaft as the second end approaches the housing.
