Abstract:
System for inspecting defects of panel device includes a to-be-inspected device, a platform for holding the to-be-inspected device, a power unit, and a light source apparatus. The light source apparatus is controlled by the power unit to provide an inspection light to the to-be-inspected device for inspecting whether or not having defects. The light source apparatus includes a cathode structure, an anode structure, a fluorescent layer, and a low-pressure gas layer. The fluorescent layer is located between the cathode structure and the anode structure. The low-pressure gas layer is filled between the cathode structure and the anode structure, for inducing the cathode to emit electrons uniformly. The low-pressure gas layer has an electron mean free path, allowing at least enough electrons to directly hit the fluorescent layer under an operating voltage.

Abstract:
A pixel structure of display apparatus includes a first substrate and a second substrate. Several cathode structure layers are disposed on the first substrate. The second substrate is a light-transmissive material. Several anode structure layers are disposed on the second substrate, and are light-transmissive conductive materials. The first substrate faces to the second substrate, so that the cathode structure layers are respectively aligned with the anode structure layers. A separation structure is disposed between the first substrate and the second substrate, for respective partitioning the anode structure layers and the cathode structure layers to form several spaces. Several fluorescent layers are respectively disposed between the anode structure layers and the cathode structure layers. A low-pressure gas is respectively filled into the spaces. The low-pressure gas has an electron mean free path, allowing at least sufficient amount of electrons to directly impinge the fluorescent layer under an operation voltage.
Abstract:
A field emission backlight module has a field emission structure with cathode and anode provided on the same plane, so that electrons directly penetrate an independently provided fluorescent powder layer to produce light. The light is emitted uniformly without the need of the conventional optical membrane. Since the light produced by the fluorescent powder layer is not blocked by the anode, the problem of charge accumulation on the fluorescent powder layer is avoided, and it is not necessary to use expensive light-transmittable conducting glass as the anode. With the cathode and the anode located at the same plane, it is not necessary to use a precision spacer to adjust the distance between the cathode and the anode, enabling the module to be manufactured at reduced cost and high good yield. When the color sequential displaying method is adopted, expensive color filters required in the conventional LCD may be omitted.
Abstract:
A plane light source is provided. The plane light source includes an anode layer, a cathode layer, a discharging gas, and at least one fluorescent layer. The discharging gas is between the anode layer and the cathode layer. The fluorescent layer is disposed on the anode layer and located between the anode layer and the cathode layer. In the plane light source, electrons is activated by discharge of the discharging gas and emitted from the cathode layer. The fluorescent layer is adapted for emitting a light when being bombarded by the electrons.
Abstract:
An enhanced plane light source has a luminescent layer independently disposed in each recess formed on a light-transmittable substrate, so that field emission electrons directly impact the luminescent layer to produce light, which is not shielded by the cathode. The enhanced plane light source also includes a substrate forming a bottom structure thereof. The bottom substrate has a metal reflection surface to increase the reflectivity and upgrade light-emitting efficiency and luminous intensity. The recesses on the light-transmittable substrate have an approximate semi-circular or semi-parabolic cross section to increase the high field region at the cathode and the effective luminescent area at the anode, so that the luminous intensity and evenness are also largely increased.
