Abstract

The plasma display screen comprises an upper substrate, a lower substrate and a plasma display cavity located between the upper substrate and the lower substrate, a light filtering layer is arranged on the surface, facing the lower substrate, of the upper substrate, and a pixel electrode layer is arranged on the surface, facing the upper substrate, of the lower substrate; a supporting structure is arranged in the plasma display cavity, an ITO film is arranged between the supporting structure and the filter layer, the lower surface of the ITO film is in contact with the upper surface of the supporting structure, and the lower surface of the supporting structure is in contact with the upper surface of the pixel electrode layer; the light filtering layer comprises a plurality of color light filters, OC layers are arranged in gaps of the color light filters, and the light filtering layer is attached to the upper surface of the ITO film through OCA glue. According to the plasma display screen, the OC layer is plated between the gaps of the color filters, the surface of the upper substrate is smooth, the ITO film is attached through the OCA, the electric field between the upper substrate and the lower substrate of the display screen can be uniform, the refresh life of the display screen is prolonged, the contrast ratio of the display screen is increased, meanwhile, the diffraction phenomenon is reduced, the color saturation of a product is increased, and the pressure resistance of the display screen is improved.

Description

technical field [0001] The invention relates to the technical field of electronic display, in particular to a plasma display screen. Background technique [0002] Existing plasma display structures, such as figure 1 As shown, from top to bottom, it is mainly composed of a glass substrate, a filter, a reflective layer microstructure and an ITO layer. The reflective layer microstructure is evenly spaced on the color filter. Due to the different requirements for color saturation, Different color filters have different thicknesses, resulting in uneven electric field of the display screen, poor pressure resistance, short refresh life, fuzzy display effect, and poor color saturation. [0003] Therefore, how to increase the refresh life, reduce the diffraction phenomenon, improve the display effect and the pressure resistance of the screen, and at the same time enhance the uniformity of the electric field has become a technical problem to be solved urgently by those skilled in the...
