Description

The display panels of the two display frames of full screen

Technical field

The utility model relates to the display panels of the two display frames of a kind of full screen.

Background technology

Development along with information material skill, flat-panel screens becomes the main flow in the electronic application product gradually, and lcd technology is a main shaft with twisted nematic display mode (TN), STN Super TN display mode (STN) and thin-film electro crystal display mode (TFT) mostly at present, it utilizes liquid crystal molecule to reverse the difference of principle, reach when on the animation display quality the inferior difference of height journey being arranged at visual angle, colour, therefore have significantly to separate in the application of product, wherein TN and STN are many based on word processor and consumer products.

General simple TN type LCD or STN type LCD, its displaying principle mainly is that liquid crystal material is placed between two transparent conducting glass, make liquid crystal molecule rotate arrangement in regular turn according to the fine groove direction of alignment film, and on transparent conducting glass, attach a polaroid respectively, after light is injected via polaroid, intercept or allow light penetration by the arrangement of liquid crystal molecule, to obtain the phenomenon of light and shade contrast, wherein TN type LCD is owing to itself only have two kinds of situations of light and shade, therefore only has monochromatic display effect, TN type LCD is then because of the relation of liquid crystal material, and the interference of light, therefore can constitute a colored display effect by the additional of a colored filter (colorfilter).

Yet, because colored STN type LCD (Color STN; CSTN) number of scanning lines height, the power consumption height, when therefore being applied to taking product such as wrist-watch, mobile telephone or computing machine, for making enough service time, usually can in a limiting time, close picture automatically, reaching power saving effect, or on product, increase the lower monochromatic TN type LCD of a power consumption in addition, make to have two screens on the identical product, to reduce its number of scanning lines by the screen that dwindles CSTN; Also can make the CSTN screen of product be divided into several parts in addition by the controlling Design of IC, and picture is shown in respectively wherein on the some, show required number of scanning lines to reduce it by dwindling of picture.

But because general taking product is originally as developing towards microminiaturization, and its display screens is just little originally, therefore if two screens are set on identical product or a screen are divided into several partly, all can cause the downsizing of literal or pattern, and feel effort when allowing the user watch picture, and reduce the comfort when using, the aforementioned in addition only wherein design of sub-fraction display frame of a little screen or screen therein, and other does not have and shows partly idle of his picture can to cause another little screen or screen when using, and has wasteness in fact; And another kind of design of closing picture automatically, for the user who needs to use this product at any time, practicality is lower.

Embodiment

Cooperate appended graphic explanation in detail by specific embodiment below, when the effect that is easier to understand the purpose of this utility model, technology contents, characteristics and is reached.

The utility model is that STN and TN display are integrated in one, selects to do the colored demonstration of STN or adds monochromatic characteristics showed to have under showing at full screen, and then reduce its power consumption.

The display panels 10 of the two display frames of one full screen, as shown in Figure 1, be that a STN module 12 is stacked at a TN module 14 tops, this STN module 12 comprises the transparency carrier 16 of two parallel interval setting up and down, the dust head is constituted by transparent glass substrate or by other transparent materials, relative two surfaces at transparency carrier 16 cover a transparent electrode layer 18 respectively, and enclose the super nematic liquid crystal molecule 20 that reverses in the gap of two transparent electrode layers 18; And the TN module 14 of lower floor comprises that the transparency carrier 16 ' that two parallel interval are provided with, its apparent surface respectively are provided with a transparent electrode layer 18 ' and enclose bar-shaped nematic liquid crystal molecule 22 in the gap.

Wherein, when STN module 12 and TN module 14 are folded up and down when establishing, as shown in Figure 1, the below transparency carrier 16 of this STN module 12 and the top transparency carrier of TN module 16 ' also can directly replace with an intermediary substrate 24, and about in the of 24 two surfaces to make the transparent electrode layer 18,18 ' that is arranged at transparency carrier 16,16 ' surface originally be formed at intermediary substrate respectively.

In addition, as shown in Figure 3, and can one first polaroid 26 and second polaroid 28 respectively be set, and between each

polaroid

26,28 and transparency carrier 1616 ', be respectively arranged with a phase compensation sheet 30 in top transparency carrier 16 outside surfaces of the STN module 12 after folded the establishing and the below transparency carrier 16 ' outside surface of TN module 14; And above transparency carrier 16 and the TN module 14 below the mutual folded STN module of establishing 12 between transparency carrier 16 ', as shown in Figure 4, also can be provided with a phase compensation sheet 30, and the upper surface of this phase compensation sheet 30, lower surface or upper and lower two surfaces both have and be pasted with one the 3rd polaroid 32 concurrently.

On the other hand, as shown in Figure 5, at transparency carrier 16 ' below the TN module 14 that is positioned at lower floor and go up between set transparent electrode layer 18 ' and be provided with an internal reflection plate 34, or as shown in Figure 6, directly an external reflection plate 36 is arranged at the outside surface of the below transparency carrier 16 ' of TN module 14, and above-mentioned internal reflection plate 34 or external reflection plate 36 also can be replaced by the reflecting plate of a half-penetration type; And in STN module 12 above 18 of set transparent electrode layers of transparency carrier 16 and lower surface thereof, and can be equipped with a colored filter 38, as shown in Figure 7, to constitute a CSTN module.

The design that the utility model combines CSTN module and TN module except the display space that effectively utilizes screen, and can be done monochromatic the demonstration in desire and the CSTN module be closed when reducing power consumption, does monochromatic demonstration to utilize the TN module; And when desire was used the CSTN module with the display color pattern, only need be closed the TN module and be got final product, and in addition, the utility model also can make CSTN module and TN module open simultaneously, and makes display frame have dual display effect.

In addition, the utility model also can improve and knownly must seek the space in addition on product, with inconvenience as local repressentation, and make particular design by IC so that the display effect replacement of full screen is known, screen is divided into the design that several partly show respectively, when being watched, the user has better visual enjoyment.

Wherein, the utility model is except for being stacked at STN module 12 the design on the TN module 14, as shown in Figure 8, also can turn upside down and makes TN module 14 be stacked at STN module 12 tops, then this moment, TN module 14 was when being provided with first polaroid 26, and its phase compensation sheet 30 can be omitted; In addition as shown in Figure 9, the utility model also can directly be formed by two STN modules, 12 folded establishing, and wherein roughly the same about the setting and the above-mentioned design of polaroid, phase compensation sheet, internal reflection plate or external reflection plate, so do not giving unnecessary details at this.

Only the above person is preferred embodiment of the present utility model only, is not to be used for limiting the scope that the utility model is implemented.So be that all equalizations of doing according to the described shape of the utility model claim, structure, feature and spirit change and modification, all should be included in the claim of the present utility model.
