Abstract: A toddler tricycle folding footboard structure consisting of a shaft hole formed through the lateral surfaces of a connective tube positioned between the rear and front brace of a toddler tricycle frame that is aligned with the shaft holes in the vertical extremities of a pair of L-shaped bracket members, a bolt inserted through the shaft holes, and a nut fastened onto it to effect a tight conjoinment, following which the pair of L-shaped bracket members remain movable at the shaft hole in the lateral surfaces of the connective tube. The horizontal extremities at the bottom aspects of the L-shaped bracket members facing outward from the two sides of the connective tube are then conjoined to a footboard such that they become a unitary structural entity, with the bolt functioning as an axle that enables free swinging for folding and unfolding to reduce space occupancy and facilitate utilization convenience.

Abstract: A display element has a luminescent body formed on a glass substrate, a glass cap with the rim bonded to the rim of the glass substrate, and a sealing layer of frit formed on the bonding region between the glass substrate and the glass cap. In encapsulating, the display element is placed between a pedestal an a pressing plate, and then a high-power laser beam is provided to penetrate the glass cap to focus on the sealing layer, resulting in sintering frit. Also, pressure is applied to the pedestal and the pressing plate.

Abstract: A display panel is disclosed. The display panel includes a substrate having an edge and a printed circuit board. A plurality of bonding electrodes are formed on the substrate, and positioned along the edge of the substrate. Each bonding electrode neither overlaps nor connects with any of the other bonding electrodes. The bonding electrodes are spaced from the edge of the substrate by a distance. A plurality of board electrodes are formed on the printed circuit board. Each board electrode neither overlaps nor connects with any other board electrodes. The position of each board electrode corresponds to that of one of the bonding electrodes. An auxiliary bonding pad is formed between the bonding electrodes and the edge of the substrate.

Abstract: A plasma display panel(PDP) is disclosed. The PDP includes a rear plate, a front plate spaced apart and positioned in parallel with the rear plate, and a plurality of barrier ribs positioned in the space between the rear plate and the front plate to define a plurality of discharge space groups. Each discharge space group includes a first discharge space, a second discharge space, and a third discharge space. Each discharge space is filled with the different discharge gases including a first, a second, and a third discharge gas for respectively emitting of one of three primary colors. The rear plate of the PDP has a reflecting layer to reflect the light and prevent the light from penetrating through the rear plate so as to increase the luminescent efficiency of the PDP.

Abstract: A plasma display device is disclosed. The plasma display device includes a plasma display panel having a display area and a non-display area, driving circuits, comparator control circuits, and heating elements mounted on the non-display area of the plasma display panel. The non-display area surrounds the display area. A part of the driving circuit and a corresponding heating element may be a Wheatstone bridge circuit. Each comparator control circuit is coupled to the Wheatstone bridge circuit so as to control the heating element. When a portion of the display area is lit, a heating element located on the adjacent non-display area is then activated through the current balance of the Wheatstone bridge circuit and under the control of the driving circuit and the comparator control circuit. Thus, the temperature difference between the display area and the non-display area is reduced.
