Technical Field

The present disclosure relates to a window cover for emitting infrared light and a sensor package including the same.

Background

Recently, electronic devices such as smart phones, tablet computers, and notebook computers are equipped with various sensor packages. These sensor packages are mainly electrical devices for receiving and measuring signals from the outside. Thus, at least a portion of these sensor packages are exposed to the outside of the electronic device in order to receive signals from the outside.

The sensor package includes a sensing element such as a light emitting element or a light receiving element, radiates a light source from the light emitting element to a target to be applied such as a headphone, and generates a measurement value by using an amount of the light source incident on the light receiving element from the target to be applied, and transmits the measurement value to various applications. Applications provide various services, such as communication services and vehicle control services, by using measurements received from sensor packages.

For example, referring to fig. 1, a vehicle 10 may be equipped with an electronic device 20, such as a tablet computer or LCD display, that may be viewed or listened to by a driver or passenger. The sensor package 30 for transmitting and receiving voice and remote control signals may be applied to the electronic device 20.

However, the conventional sensor package 30 has a limited pointing angle of light emitted from the light emitting element to a target to be applied, thereby inevitably limiting the usable range.

For example, when the LCD display is installed behind the headrest 11 of the driver seat, a passenger seated in the rear seat of the driver seat can freely transmit a signal to the LCD display using a wireless headset or by operating a remote controller, but since the light pointing angle (light distribution angle) of the sensor package installed on the LCD display screen is limited, a passenger seated in another seat cannot smoothly transmit or receive a signal for operation.
