Problems solved by technology

but if figure 2 As shown, for an AVN terminal with a separate configuration of the display and the head unit of the audio, since the display used to generate touch calibration data during the production process and the head unit of the audio that stores the touch calibration data cannot be sold as a set, it is difficult to prevent the occurrence of touch deviation.
Also, even if sold as a set, when the head unit is replaced due to a failure, the touch calibration data stored in the head unit does not match the touch deviation of the display, resulting in a large touch deviation

Embodiment Construction

[0022] The aforementioned and additional features of the present invention will become more apparent by referring to the preferred embodiments described with reference to the accompanying drawings. The present invention will be described in detail below so that those skilled in the art can easily understand and implement it through the embodiments.

[0023] image 3 It is a block diagram showing a multimedia terminal according to an embodiment of the present invention.

[0024] As shown in the figure, the multimedia terminal includes an audio host 100 and a separate touch display 200 . The head unit 100 can include audio and video and navigator functions. It is also possible to further include a telematics service function. The role of the audio head unit 100 is to connect the vehicle input power required for the work to the separate touch display 200 and to be able to communicate with the separate touch display 200 . For example, the audio host 100 communicates with the s...

Abstract

The invention discloses a vehicle-mounted multimedia terminal and a method thereof for preventing touch deviation of a separate display. According to the present invention, the touch calibration data is stored in the internal memory of the separate display, and the head unit uses the touch calibration data stored in the separate display to correct the touch input. Therefore, even for a multimedia terminal with a separate display, touch deviation can be effectively corrected.

Description

technical field [0001] The invention relates to a vehicle-mounted multimedia terminal with a separate display, in particular to a technology for preventing deviation of touch input to the display. Background technique [0002] When the touch panel is assembled on the display, it is easy to misalign due to the inability to accurately align the assembly position. As a result, touch bias occurs across displays. Therefore, touch calibration is performed for touch correction during product production, and the touch calibration data generated by this is stored in the head unit (Head Unit). [0003] Therefore, if figure 1 As shown, for a multimedia terminal in which the display and the audio host (body) form an integrated form, that is, an Audio Video Navigation (AVN) terminal, the touch deviation can be prevented. but if figure 2 As shown, for an AVN terminal whose display and head unit are separated, the display used to generate touch calibration data and the head unit stori...
