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...

Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0032] A vehicle head-up display based on a TOLED screen, including a car ECU system 5, an OBD interface 6, an OBD module 7 with an independent MCU, a HUD device 3, a TOLED screen 4, and a smart phone APP8. The OBD module 7 includes an MCU 71 and a Bluetooth module 72 , and the HUD device 3 includes an MCU 31 , two Bluetooth modules and a display control module 32 . The bluetooth module in HUD device 3 such as figure 2 As shown, they are represented by Bluetooth module 1 and Bluetooth module 2 respectively.

[0033]Wherein, the OBD module 7 communicates with the automobile ECU system 5 through the OBD interface 6 to obtain vehicle information such as vehicle speed, engine speed, fault codes, etc., and then communicates with the Bluetooth module 1 of the HUD device 3 through the Bluetooth module 72, and the obtained The data is sent to the HUD device 3 .
