Description

Technical Field

[0001] This utility model relates to the field of backlight technology, and in particular to an OLED backlight component. Background Technology

[0002] Backlight is a light source located behind an LCD display, and its luminous effect directly affects the visual effect of the LCD module.

[0003] OLEDs are a type of current-driven organic light-emitting device that emits light through the injection and recombination of charge carriers. OLED backlights utilize OLED light sources. Under the influence of an electric field, holes generated at the anode and electrons generated at the cathode move and are injected into the hole transport layer and electron transport layer, respectively, migrating to the emissive layer. When these two electrons meet in the emissive layer, they generate excitons, which excite the light-emitting molecules to ultimately produce visible light.

[0004] The front frame and back panel of the OLED backlight are fixed to position the backlight components. When fixing the front frame and back panel, simply covering the back panel with the front frame does not provide sufficient stability for the connection.

[0005] In view of this, we propose an OLED backlight assembly. Utility Model Content

[0032] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0033] Example 1: An OLED backlight assembly, see Figures 1 to 4 The backlight body 1 includes a horizontal polarizer, a color polarizer, a liquid crystal, a TFT glass, a vertical polarizer, a circuit, a diffuser, a frame, a backlight, etc., and also includes a back plate 4 and a front frame 2. The back plate 4 is arranged at the bottom of the backlight body 1. The front frame 2 is covered on the backlight body 1. The bottom two sides of the front frame 2 are respectively connected to the two ends of the back plate 4 through the connecting structure 3.

[0034] The connecting structure 3 includes a connecting strip 301, a connecting plate 303, a fixing strip 308, and a retaining strip 307; the connecting strip 301 is fixed to the top wall of the slot at the bottom side of the front frame 2; the connecting plate 303 is arranged below the connecting strip 301; two spring pieces 306 are symmetrically arranged between the connecting strip 301 and the connecting plate 303; the fixing strip 308 is fixed to the end of the back plate 4; the retaining strip 307 is fixed to the bottom inner side of the connecting plate 303; the retaining strip 307 engages with the retaining groove 3081 on the outer side of the fixing strip 308.

[0035] This utility model, by setting up a connecting strip 301, a connecting plate 303, a spring piece 306, a fixing strip 308, and a locking strip 307, has the advantage of quick docking and positioning when the front frame 2 covers the back plate 4, so that the front frame 2 and the back plate 4 are stably connected. It solves the problem that the connection stability is not enough when the front frame 2 and the back plate 4 are fixed by simply covering the back plate 4 with the front frame 2.

[0036] Specifically, the spring 306 is arc-shaped, and the arched ends of the two springs 306 are opposite to each other. The arc-shaped spring 306 bends smoothly, and when the retaining strip 307 is squeezed outward, it pushes the connecting plate 303 to rotate outward.

[0037] Furthermore, a U-shaped strip A302 is fixed to the bottom end of the connecting strip 301 by a screw 305, and a U-shaped strip B304 is fixed to the top end of the connecting plate 303 by a screw 305. The opposite sides of the U-shaped strip A302 and the U-shaped strip B304 are respectively fixedly connected to the two ends of the spring piece 306. The screw 305 passes through the U-shaped strip A302 and the U-shaped strip B304 with corresponding threads, and is screwed into the bottom end of the connecting strip 301 and the top end of the connecting plate 303 respectively.

[0038] This utility model has the advantages of detachable spring 306 by setting U-shaped strip A302, U-shaped strip B304 and screw 305, and it is easy to install spring 306.

[0039] Furthermore, the bottom outer side of the retaining strip 307 is arc-shaped, and the retaining strip 307 is adapted to the retaining groove 3081. When the retaining strip 307 moves down, it is smoothly pushed open when the arc-shaped side of the retaining strip 307 contacts the outer side of the fixing strip 308.

[0040] It is worth noting that there is a gap between the outer side of the fixing strip 308 and the inner bottom of the connecting plate 303, which causes the arc-shaped side of the clip 307 to be pushed away in an arc when it comes into contact with the outer side of the fixing strip 308.

[0041] Working principle: Using the device of this utility model, U-shaped strip A302 is stuck at the bottom end of connecting strip 301, and U-shaped strip B304 is stuck at the top end of connecting plate 303. Screw 305 passes through U-shaped strip A302 and U-shaped strip B304 with corresponding threads and is screwed into the bottom end of connecting strip 301 and the top end of connecting plate 303 respectively. Install spring piece 306; backlight body 1 is installed on back plate 4 in sequence, and front frame 2 covers back plate 4. When the arc side of the locking strip 307 contacts the outside of the fixing strip 308, it is squeezed open, pushing the connecting plate 303 to rotate outward. The spring piece 306 bends accordingly. After the front frame 2 is fully covered, the locking strip 307 corresponds to the slot 3081. The spring piece 306 rebounds, causing the connecting plate 303 to rotate. The locking strip 307 is engaged in the slot 3081, thereby positioning the front frame 2 and back plate 4. The front frame 2 covers the backlight body 1.

Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
