Abstract: A display may have an array of pixels. Display driver circuitry may supply data and control signals to the pixels. Each pixel may have seven transistors, a capacitor, and a light-emitting diode such as an organic light-emitting diode. The seven transistors may receive control signals using horizontal control lines. Each pixel may have first and second emission enable transistors that are coupled in series with a drive transistor and the light-emitting diode of that pixel. The first and second emission enable transistors may be coupled to a common control line or may be separately controlled so that on-bias stress can be effectively applied to the drive transistor. The display driver circuitry may have gate driver circuits that provide different gate line signals to different rows of pixels within the display. Different rows may also have different gate driver strengths and different supplemental gate line loading structures.

Abstract: A heat-dissipation fan comprises a hollow cylinder body, a fixing pillar, a stator, a fan wheel, a bearing and bearing plate. The fixing pillar comprises a free end and a fixing end fixed at the hollow cylinder body. The stator is installed at the hollow cylinder body being installed at the bearing plate. The fan wheel comprises a top plate, an outer ring wall, an inner ring wall and a penetration hole formed at the top plate. The inner ring wall surrounds the penetration hole, the hollow cylinder body and the stator are located between the outer ring wall and the inner ring wall, and the bearing is coupled to the inner ring wall. The free end of the fixing pillar is protruded to a top surface of the top plate, which results a supporting surface and the top surface being spaced apart by a first spacing.

Abstract: A thermal food storage cabinet has a sealed box with a thermally insulated compartment, a freezer compartment and a refrigeration compartment, a compressor, a condenser, evaporator and thermal expansion valve. The thermally insulated compartment has a heat-conducting panel. The compressor, the evaporator and the thermal expansion valve are mounted in the thermal food storage cabinet to cool the freezer compartment and the refrigeration compartment. The condenser is mounted on the heat-conducting panel so heat dissipated by the condenser can flow into the thermally insulated compartment.

Abstract: A rack includes three sides each having a protrusion on the first end thereof and a recess defined in the second end thereof so that the three sides are connected to be a triangle rack by engaging the three protrusions with the three recesses. Each side has two grooves defined in the inside thereof and two ridges extending from the outside thereof. Three separators each have two protrusions for being engaged with the corresponding grooves of the three sides to from a small triangle or a rhombus. Each separator has two concavities defined in the inside thereof so as to receive the ridges when attached to the outside of the sides.

Abstract: A pocket structure includes a first part having a ring body with a groove defined in the lower end thereof and a second part having a bottom with a periphery wall extending from the bottom. A flange extends from the top of the peripheral wall of the second part and is sized to be fitted into the groove. The ring body has a plurality of tapered lugs extending radially inward therefrom so that the flange slides over the tapered lugs and securely engaged with the groove.

Abstract: A seat device attached to a baggage handcart includes a base attached to the baggage handcart with two rear legs disposed perpendicularly thereto, the base having two frames extending therefrom for a seat plate pivotally engaged thereto which has two first receiving members and a second member disposed to a bottom, a front leg pivotally disposed to a front end of the seat plate, the front leg having a passage defined by a non-circular periphery so as to respectively receive a block and a rod therein, the block having a slit defined therein for receiving an eccentric protrusion extending from the rod such that when the rod rotated to let the protrusion be located in the slit, the block is expanded to securely contact the non-circular periphery of the passage.
