A pressure sensor module is disclosed. The pressure sensor module comprises a sensing element (1) mounted on a front side (3) of a support member (5). The support member (5) comprises a hole (7) through the support member (5) from the front side (3) to a back side (9). The sensing element (1) covers the hole (7) at the front side (3). A back side barrier (6) provided at the back side (9) of the support member (5) surrounds a surface of the back side (9) of the support member (5) and forms an enclosed area (8), wherein the enclosed area (8) and the hole (7) form a pressure channel (10). A back side protective member (2) fills the hole (7) and at least partially the enclosed area (8). The support member (5), back side barrier (6) and back side protective member (2) form a module that can be placed during production of the pressure sensor in a housing of the pressure sensor.

Disclosed herein are a coating solution for the formation of a dielectric thin film and a method for the formation of a dielectric thin film using the coating solution. The coating solution comprises a titanium alkoxide, a β-diketone or its derivative, and a benzoic acid derivative having an electron donating group. The method comprises spin coating the coating solution on a substrate to form a thin film and drying the thin film at a low temperature to crystallize the thin film. The titanium-containing coating solution is highly stable. In addition, the coating solution enables formation of a thin film, regardless of the kind of substrates, and can be used to form dielectric thin films in an in-line mode in the production processes of PCBs.

A display device, and a blower thereof are disclosed. The display device includes an axial flow fan within a case, which has a display panel encased therein. The axial flow fan is provided in a width direction within the case, so that, while being rotated within the case, the axial flow fan generates forced air flow suitable to the case. The forced air flow is generated in a forward direction along with air flow by natural convection within the case.
