Abstract

The utility model relates to a sectional displaying super-thin display. A display device is composed of a strip-shaped cathode electrode (1), a control electrode (2), a focusing electrode (3) and a deflection electrode (4). A fluorescent screen is divided into at least three display sections, and each of the display sections corresponds to a group of display components. The utility model is based on the prior art and has the advantages of easy technical realization, simple structure, good display quality, easy realization of high definition and easy complanation of pipe surface. Thereby, the utility model is a novel super-thin display product.

Description

The ultrathin display unit of segmentation display type

The utility model relates to a kind of display unit of image, the ultrathin display unit of particularly a kind of segmentation display type.

In the prior art, widely used is electron gun formula picture tube, by the electron gun divergent bundle, through modulation, the scanning of focusing post deflection, on phosphor screen, form image, for changing into image, electronic signal provides condition, but its image effect is relatively poor, the picture tube size is thick, make product seem very heavy,, produce super thin product in order to promote clearness, people develop products such as plasma display, LCD, field emission display screen, Digital Micromirror Device in succession, for the development of product lays the first stone.

The purpose of this utility model provides the ultrathin display unit of a kind of improved segmentation display type, improves reproduced image resolution, dwindles product thickness and adapts to the consumption tide needs, promotes production development.

The purpose of this utility model can realize by following technical measures: this display unit is divided into three sections display segments at least to phosphor screen, every display segment correspondence is provided with one group of display module, display module is provided with the bar shaped negative electrode, at least two control utmost points are set abreast in bar shaped negative electrode front, each controls extremely that correspondence is provided with focusing electrode, and the focusing electrode front is provided with deflecting electrode.The electron beam that the bar shaped negative electrode sends is through the modulation of the control utmost point, and focusing electrode scans corresponding phosphor screen display segment by the electrostatic deflection electrodes controlling electron beam after focusing on again, forms one section image, constitutes jointly general image by each section image.

Concrete structure of the present utility model and embodiment are provided by the following drawings:

Fig. 1 is the structure chart of a display segment of the present utility model;

Fig. 2 is an enforcement illustration of the present utility model.

The utility model is described in further detail below with reference to accompanying drawing: with reference to Fig. 1, the width of every display segment is 3～6 centimetres approximately, each display segment is all to there being one group of display module, every group of display module is provided with bar shaped negative electrode [1], several control utmost points [2] are set abreast in bar shaped negative electrode [1] front, the number of the control utmost point [2] is determined that by display resolution each control utmost point [2] has deflecting electrode [4] all to focusing electrode [3] should be arranged in focusing electrode [3] front.When practical application, as Fig. 2 embodiment, 25 cun of picture diagonal, resolution 800 * 600, point distance: 0.6mm, phosphor screen is divided into 13 display segments, every section display frame height 3cm, 13 on bar shaped negative electrode, 2400 of the control utmost points, 13 of deflecting electrodes, each display segment image constitutes jointly general image.

The utility model is based on prior art, and technical realization is easy, and is simple in structure, and display quality is good, realizes high definition easily, and the picture tube face easily realizes complanation, and thin thickness for ultra-thin production provides condition, is the picture tube of Nover practical.
