Description
Technical field
The invention relates to a kind of display panel, and particularly relevant for a kind of curved face display panel.
Background technology
Along with the progress of science and technology, the technology of display is development constantly also.Gently, thin, short, little flat-panel screens (Flat Panel Display, FPD) replace gradually the thick and heavy negative electrode crt display of tradition (Cathode Ray Tube, CRT).Nowadays, because the frivolous characteristic of flat-panel screens, flat-panel screens more is configured on nonplanar surface of many buildingss or electronic equipment.
Fig. 1 is a kind of diagrammatic cross-section of existing curved surface display panels.Please refer to Fig. 1, the curved surface display panels 100 of prior art is behind the glass substrate 110 clamping liquid crystal layers 120 with two plate planes, fix two sheet glass substrates 110 and liquid crystal layer 120 with the chase (not illustrating) that is curved surface again, so that display panels 100 presents crooked state.Yet chase is also non-homogeneous to force in two sheet glass substrates 110, and glass substrate 110 also can be different with the stress concentration degree of centre at the edge.Therefore, curved surface display panels 100 spacing of two sheet glass substrates 110 of centre often appears and can be less than the spacing of edge.Thus, will cause curved surface display panels 100 display abnormalities.
Fig. 2 is the diagrammatic cross-section of another kind of prior art curved surface display panels.Please refer to Fig. 2, the curved surface display panels 100 the same unfixed problems of spacing that have two sheet glass substrates 210 of existing curved surface display panels 200 and Fig. 1.Yet curved surface display panels 200 has more touch controllable function.This touch controllable function is to reach by a plurality of pressure transducers 230 that are arranged in the curved surface display panels 200.When the user pushed curved surface display panels 200, the sensing post 240 at this place can contact downwards and trigger pressure transducer 230, uses and reaches touch controllable function.Yet, if the spacing of two sheet glass substrates 210 of the centre of curved surface display panels 200 is too small, may causes the sensing post 240 at this place to contact normally and trigger pressure transducer 230, make touch controllable function lose efficacy.
Summary of the invention
Technical matters to be solved by this invention is, a kind of curved face display panel is provided, and can solve the uneven problem of spacing of substrate.
A kind of curved face display panel of the present invention comprises one first substrate, one second substrate, a display medium, a plurality of first distance piece and a plurality of island boosting pieces.Second substrate has a relative first surface and a second surface.First surface is towards first substrate, and second surface is first substrate dorsad.The display medium and first spacer arrangement are between first substrate and second substrate.Island boosting pieces is disposed on a plurality of blocks of first surface of second substrate.Island boosting pieces has different-thickness on different blocks.
Another kind of curved face display panel of the present invention comprises one first substrate, one second substrate, a display medium and first distance piece.The display medium and first spacer arrangement are between first substrate and second substrate.At least along a first direction, the floorage of first distance piece is successively decreased outward by the mediad of second substrate, and second substrate is bending along the section of first direction.
Based on above-mentioned, the thickness of the island boosting pieces of curved face display panel utilization change diverse location of the present invention or the floorage of distance piece guarantee that the spacing of substrate is even, to promote display quality.
For above-mentioned feature and advantage of the present invention can be become apparent, embodiment cited below particularly, and cooperate appended graphic being described in detail below.
