Abstract
A light emission device and a display device provided with the light emission device are provided. The light emission device includes first and second substrates opposing each other. An electron emission unit is arranged on the first substrate. A light emission unit is provided on the second substrate and has an active area and an inactive area surrounding the active area. An arcing preventing member is formed on the inactive area. The arcing preventing member is formed to satisfy the condition: 0.3≦H/W≦1.0, where W is a width of the active area and H is a height of the arcing preventing member.
Claims15
A light emission device comprising:
- a first substrate and a second substrate opposing each other;
- an electron emission unit on the first substrate;
- a light emission unit on the second substrate, the light emission unit having an active area and an inactive area surrounding the active area;
- and
- an arcing preventing member on the inactive area,
- wherein the arcing preventing member satisfies the following condition:
- 0.3≦H/W≦1.0
- where, W is a width of the active area and H is a height of the arcing preventing member in a direction from the second substrate to the first substrate.
A display device comprising
- a display panel for displaying an image, and
- a light emission device for emitting light toward the display panel,
- wherein the light emission device comprises:
- a first substrate and a second substrate opposing each other;
- an electron emission unit on the first substrate;
- a light emission unit on the second substrate, the light emission unit having an active area and an inactive area surrounding the active area;
- and
- an arcing preventing member on the inactive area,
- wherein the arcing preventing member satisfies the condition:
- 0.3≦H/W≦1.0, where, W is a width of the active area and H is a height of the arcing preventing member in a direction from the second substrate to the first substrate.
A light emission device comprising:
- a first substrate and a second substrate opposing each other;
- an electron emission unit on the first substrate;
- a light emission unit on the second substrate, the light emission unit having an active area and an inactive area surrounding the active area;
- and
- an arcing preventing member protruding from the inactive area toward the first substrate, the arcing preventing member having a width W corresponding to a width of the active areas and a protrusion height H toward the first substrate,
- wherein the arcing preventing member is sized such that a H/W ratio is within the range 0.3≦H/W≦1.0, and
- the H/W ratio is selected from within the range 0.3≦H/W≦1.0 to set a desired anode driving voltage to be less than an arcing voltage.
