Abstract: The present invention relates to a display screen mask structure using a shielding frame and a manufacturing method thereof. A combination of a shielding frame body and a plurality of substrate units, or a combination of a surface-printing outer frame portion and a surface-printing separated inner frame portion of a shielding frame body to be connectively overlapped on a single or multiple layers of light-transmitting thin film substrate, is overlapped on a self-light emitting display element of a photoelectric device panel. The light, scattered from the self-light emitting display element, is filtered and reflected by and concentratedly radiated from the outer frame portion and the separated inner frame portions of the shielding frame body, so that the light radiated from the self-light emitting display element of the photoelectric device panel is more concentratedly purified and has an enhanced color contrast of the dark tone.

Abstract: The present invention is related to a display screen mask structure, providing a plurality of arranged and combined substrate units overlapped on a self-light emitting display element of a photoelectric device panel. The light, radiated from the self-light emitting display element, is filtered and reflected by and concentratedly radiated from a light-reflecting layer overlapped on the light-transmitting bodies of the substrate units, so that the light leakage can be prevented and an external strong light can be shielded by the light-shielding layer overlapped on the light-reflecting layer, the light generated from the self-light emitting display element can be efficiently concentrated, and the phenomenon such as whitening and low image contrast ratio occurred by an external light radiating on a display panel can be improved.

Abstract: A stove structure includes a stove body. The stove body has a heat source portion and a wall portion. The wall portion has an inner wall and an outer wall. The inner wall and the outer wall are connected by a plurality of cross-section conducting members. Between the inner wall, the outer wall and the cross-section conducting members is provided with a low conductivity coefficient member. The cross-section conducting members extend the heat conduction distance and decrease the contact area of heat conduction. The lower conductivity coefficient member and the cross-section conducting members lower the heat conduction rate. The temperature of the outer wall is lowered to a second temperature and the temperature in the heating portion of the stove body is kept at the first high temperature.
