Problems solved by technology

In the plasma display, the luminous efficiency has a great relationship with the pixel size, the smaller the size, the lower the efficiency, and the contribution of blue light to the brightness is almost negligible, so after adopting the above measures, the brightness and luminous efficiency of the display must be further reduced
According to the performance of the current blue phosphor, the luminous flux emitted by the blue sub-pixel needs to be doubled to achieve an ideal color temperature. For the currently widely used plasma display structure, the luminous efficiency will be almost halved.

Abstract

The invention relates to a plasma display panel provided with a triangular pixel structure and driven according to sub-row branch fields, which belongs to the technical field of display. Each row of the display panel comprises two sub-rows; a mutual misalignment of about one pixel size exists between the sub-pixels with a same color between the two sub-rows; and the two sub-rows form triangular pixels and inverted triangular pixels, which are arranged alternately in the horizontal direction. The shape of sub-pixels is rectangular; fluorescent powder is coated on the bottom surfaces and the lateral surfaces of barriers of the sub-pixels; and a curve or linear addressing electrode passes through two columns of adjacent barriers. Convergence electrodes of an X electrode on a front plate are arranged between two rows, convergence electrodes of a Y electrode are arranged between two sub-rows in each row; the transparent X electrode and the Y electrode are arranged on the upper sides and thelower sides of the convergence electrodes respectively. The display adopts a space-time mixed color displaying mode with one frame and two fields. Compared with the prior art, the plasma display panel has the characteristics of simple structure, high luminous efficiency, and is suitable for mass production.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a plasma display screen with a triangular pixel structure and field-driven sub-rows. Background technique [0002] Plasma Display (PDP) is an important device for large-screen flat-panel displays. Internationally, plasma TVs occupy an important market for large-screen flat-panel TVs, and their domestic market share is far behind that of LCD TVs. The main reason for this phenomenon is that the plasma TV is relatively heavy, consumes a lot of power, and its service life is not very ideal. From the perspective of display performance, the dynamic resolution of the plasma display screen and the ability to express dark pictures are very good. If problems such as power consumption and lifespan can be solved, it may become a mainstream device for next-generation flat panel displays. [0003] The plasma display appeared half a century ago, and its performance has been conti...
