The invention relates to an automatic heat preservation, energy saving and air-entrapping concrete brick wall and a manufacturing method thereof. The invention is characterized that: a heat preservation wall plate is protruded, relative to the outer surfaces of a beam and a stand column or a concrete plate, 20 to 50 millimeters or flatly bricked; beam and column part heat preservation layers are bonded on the outer surfaces of the beam and the stand column or the concrete plate; and alkali-proof grids or steel mesh sheets are paved on the surfaces of the heat preservation layers. During bricking of the wall, the comprehensive performance of the heat preservation wall can be enhanced under the condition of no addition of the heat preservation layers on the whole wall by using energy saving and air-entrapping concrete bricks and heat preservation bricking mortar as well as heat preservation processing measures taken on hot bridge parts such as the beam, the column and the like, so the requirement of a periphery protective structure of a building wall can be met, and heat energy loss due to the hot bridges formed in mortar joints of the wall can be avoided effectively; therefore, the design standard requirement of China on heat preservation and energy saving of a building is met, and the manufacturing cost of the wall and the comprehensive cost of the building are reduced greatly.

The invention discloses a burning-and-steam-curing-free alkaline slag brick. The burning-and-steam-curing-free alkaline slag brick is prepared from the following raw materials in part by weight or volume: 20 to 200 parts of alkaline slag or vulcanized alkaline slag, 0 to 200 parts of magnesium slag, 0 to 200 parts of fly ash, 0 to 200 parts of coal cinder, 0 to 200 parts of tailing sand, 0 to 200 parts of limestone powder, 0 to 200 parts of coarse aggregate, 0 to 200 parts of oil shale waste, 0 to 200 parts of activated coagulation aiding material, 0 to 200 parts of waste sand, 2 to 20 parts of cement, and a proper amount of water. The raw materials are stirred and then are fed into a block making machine for vibration compression molding, and a finished product is obtained through natural curing or solar warming-up curing for 7 to 28 days. The burning-and-steam-curing-free solid bricks, perforated bricks, hollow blocks, floor tiles, road edge bricks, grass planting bricks, slope protection bricks and fence railings of different specifications can be produced by replacing different mold machines. Industrial waste slag is utilized to turn harm into good, material selection is flexible, the process is simple and convenient, the cost is low, the strength of the product is high, and the burning-and-steam-curing-free alkaline slag brick has excellent development and application prospects.

The invention discloses a display device which comprises a backlight module and a liquid crystal display module. The backlight module is provided with a through hole. The liquid crystal display modulecomprises a display panel and a lower polarizing film and an upper polarizing film which are arranged on two opposite surfaces of the display panel. The lower polarizing film is provided with a firstvia hole, and the upper polarizing film is provided with a second via hole corresponding to the first via hole, wherein edges of both sides of the second via hole are coated with light shielding parts. Therefore, the risk of side light leakage of the first via hole and the second via hole of the liquid crystal display module is avoided, and an image pick-up effect of an image pick-up module and the market competitiveness are reinforced.
