Problems solved by technology

On the other hand, car lights mostly adopt curved surface design. In order to cater to the effect of car light shape, OLED lamps also need to use special-shaped lamps. Furthermore, due to the high brightness requirements of car lights, OLED screens cannot be as bright as display screens. The design of fully regular pixel graphics is driven by row and column scanning, so the existing OLED light sheet has been difficult to meet the design requirements of OLED lights

Embodiment 1

[0046] Please refer to Figure 1a , this embodiment provides an OLED light sheet 100, the shape of the light sheet 100 is an irregular irregular shape surrounded by three straight sides and a circular arc edge; the light sheet 100 is provided with a display area 110 and a non- Display area 120, wherein display area 110 includes:

[0047] At least one main display area 114 has a regular shape and is formed by splicing several main light emitting units 111 of the same shape;

[0048] The display peripheral area 115 is composed of a peripheral I area 116 and a peripheral II area 117. The peripheral I area 116 is formed by a number of I peripheral light-emitting units 112 with regular shapes, and the peripheral II area 117 is formed by a number of II peripheral light-emitting units 113. form.

[0049] Wherein, the peripheral II area 117 is the part in the display area 110 except the display body area 114 and the peripheral I area 116, that is, the closed graphic part surrounded ...

Embodiment 2

[0082] like Figure 5 As shown, on the basis of Embodiment 1, the OLED light sheet provided by this embodiment is snowflake-shaped, which has 19 display main areas 114 and 16 display peripheral areas 115 of three types; the display main areas 114 are respectively located in the center The first display main area 114a, the second display main area 114b located on the branches, the third display main area 114c located on the branches and leaves; the first display main area 114a located in the center includes an area of ​​17.7mm 2 There are 32 right-angled triangular main light-emitting units 111 in total, and the rectangular second display main area 114b on the branch has an area of ​​8mm 2 There are 32 right-angled triangle I peripheral light-emitting units 112 in total, and the rectangular third display body area 114c on the branches and leaves includes an area of ​​8 mm. 2 There are four right triangle II peripheral light emitting units 113; the I peripheral light emitting u...

Embodiment 3

[0085] like Image 6 As shown, on the basis of Example 1, the OLED light sheet provided in this example is leaf-shaped, which has a display main area 114 and a display peripheral area 115; the display main area 114 includes 64 light-emitting areas with an area of 25mm 2The main light-emitting unit 111 shows that the peripheral area 115 includes a peripheral I area 116 and a peripheral II area 117; the peripheral I area 116 contains 25 regular I-th peripheral light-emitting units 112 (filled with oblique lines), and the peripheral II area includes several different Regular second peripheral light emitting unit 117 (box filled). When all the light-emitting units in the display area are lit, it can form a leaf shape; when some main light-emitting units are selected to be lighted in the central display main area alone, some basic car light indication shape requirements can be realized.

Abstract

The invention discloses an OLED lamp sheet and an OLED car lamp. A display area of the lamp sheet comprises: at least one display main body area which is regular in shape and is formed by splicing a plurality of main light-emitting units with the same shape; and a display peripheral area, which is composed of a peripheral area I and a peripheral area II, wherein the peripheral area I is formed by a plurality of peripheral light-emitting units I which are regular in shape. According to the OLED lamp sheet, the display area of the OLED lamp sheet is designed to comprise at least one display main body area and at least one display peripheral area, wherein the shape of the display main body area is regular, various display elements can be achieved, and therefore, various modes such as steering, rhythm, warning and greeting can be achieved; and the display peripheral area can realize whole-screen display of the OLED lamp sheet, so the special-shaped modeling requirement of an automobile tail lamp is met, and under the design requirement that the number and the positions of OLED lamp sheets are limited, the utilization rate of brightness space and area is increased, and high-difficulty automobile lamp design requirements can be met.

Description

technical field [0001] The present disclosure generally relates to the technical field of lighting OLED, and in particular relates to an OLED lamp sheet and an OLED vehicle lamp. Background technique [0002] OLED is gradually being widely accepted in the automotive field. With the improvement of automobile intelligence and comfort requirements, the space of car lighting design is compressed, and the number of OLEDs is gradually decreasing, but OLEDs are required to display more and more content. Therefore, OLEDs with multiple light-emitting areas will become a trend . On the other hand, car lights mostly adopt curved surface design. In order to cater to the effect of car light shape, OLED lamps also need to use special-shaped lamps. Furthermore, due to the high brightness requirements of car lights, OLED screens cannot be as bright as display screens. The design of fully regular pixel graphics is driven by row and column scanning, so the existing OLED light sheet has been...
