Vehicle-mounted head-up display based on TOLED screen and mounting application method

Abstract

The invention discloses a vehicle-mounted head-up display based on a TOLED screen. The vehicle-mounted head-up display comprises the TOLED screen and an HUD device, wherein the HUD device is communicated with an automobile system through an OBD interface; the vehicle-mounted head-up display is characterized by further comprising an OBD module; the OBD module comprises an MCU, a Bluetooth module and an MCU control Bluetooth module; the HUD device comprises an MCU, a Bluetooth module, a display control module, a voice control module, an MCU control Bluetooth module and a voice control module; the OBD interface is connected with an automobile ECU system; the OBD interface is connected with the OBD module; the OBD module is communicated with the automobile ECU system through the OBD interface and acquires state information of a vehicle; the OBD module is communicated with the HUD device through the Bluetooth module; the display control module controls the TOLED screen to display the state information of the vehicle; the voice control module controls a loudspeaker to send part of data.

Description

technical field [0001] The invention relates to a vehicle head-up display, in particular to a vehicle head-up display based on a TOLED screen. Background technique [0002] The head-up display (HUD, Head-Up Display) was first applied in aviation technology. It displays flight or landing information by projection on the front window of the aircraft, so that the pilot does not need to look down at the instrument panel frequently during the operation, thereby increasing the flight time. time safety. When this technology is extended to the field of automotive electronics, a car head-up display is produced, which displays relevant information such as vehicle speed and engine speed on the front windshield for the driver to view, improving driving safety. [0003] TOLED (Transparent Organic Light-Emitting Diode, transmissive organic light-emitting display), transparent OLED without backlight. The screen has the characteristics of low driving voltage, active light emission, wide v...

AI Technical Summary

Problems solved by technology

[0005] ①The HUD is directly connected to the OBD port of the car, which not only makes wiring difficult and affects the appearance, but also for models whose OBD port is near the brake or accelerator pedal, the connection line may affect the driver's driving and thus affect driving safety

[0006] ②Using the method of pasting an optical film on the windshield to project the information on the display panel. Since the windshield of a car is generally thick, double images will appear when the inside and outside sides are emitted at the same time, which will affect the visual effect.

Moreover, under strong sunlight, the projected image is almost blurred and invisible

[0007] ③The HUD does not display the navigation information, which causes the driver to still need to look down at the navigator or mobile phone while driving, which affects driving safety

[0008] ④HUD has no expandable functions, such as vehicle-to-vehicle communication

There are too many electronic products in the car, which is troublesome to use

[0009] ⑤HUD does not have an integrated voice prompt module, and the driver cannot be notified by voice in a timely manner for more important and real-time information
