Description

Display device for vehicle Technical Field The present invention relates to a vehicle display device, and more particularly, to a vehicle display device capable of stably displaying a vehicle warning image. Background A vehicle is a device that moves in a direction desired by a user who gets on a vehicle. Typical examples may be exemplified by automobiles. On the other hand, in view of convenience for a user using the vehicle, a vehicle display device is mounted in the vehicle. For example, a display is configured at a dashboard or the like to display various information. On the other hand, in order to display vehicle running information and the like, there is a trend to mount various displays such as AVN (Audio Video Navigation: audio visual navigation) displays, head-up displays for outputting projection images to windshields, and the like, on vehicles in addition to dashboards. Conventionally, a vehicle warning image based on a lamp system has been displayed, but there is a current trend to display the vehicle warning image by a display in a vehicle. In order to display such a vehicle warning image, a signal processing device in a vehicle outputs a video signal including the vehicle warning image, but there is a problem in that the vehicle warning image cannot be displayed when the signal processing device fails. Disclosure of Invention Problems to be solved by the invention The invention provides a display device for a vehicle, which can stably display a vehicle warning image. Another object of the present invention is to provide a vehicle display device capable of preventing degradation of a vehicle warning image. Means for solving the problems In order to solve the above problems, a display device for a vehicle according to an embodiment of the present invention includes an organic light emitting panel, and a drive control unit that outputs a drive signal to the organic light emitting panel, and the drive control unit outputs at least one vehicle warning image to the organic light emitting panel using at least one vehicle warning image stored in a memory. On the other hand, the drive control section can receive the plurality of vehicle warning images from the signal processing device and output the plurality of vehicle warning images to the organic light emitting panel separately from at least one vehicle warning image. On the other hand, the drive control portion can perform degradation compensation on at least one vehicle warning image. On the other hand, in the case where the alpha blending region is included in the first vehicle warning image of the at least one vehicle warning image, the drive control section can check the degradation of the alpha blending region using the mask layer corresponding to the alpha blending region, and execute degradation compensation based on the degradation check result. On the other hand, in the case where the alpha blending region is included in the first vehicle warning image of the at least one vehicle warning image, the drive control section can perform the luminance compensation for each color of the alpha blending region separately when compensating for the degradation of the alpha blending region. On the other hand, when the alpha blending value of each color of the alpha blending region is different, the drive control unit can control the luminance compensation value of each color of the alpha blending region to be different when compensating for the degradation of the alpha blending region. On the other hand, the drive control section can execute a pixel displacement, a first axis displacement, or a second axis displacement of the at least one vehicle warning image or change the brightness of the at least one vehicle warning image when the at least one vehicle warning image is determined to be degraded. On the other hand, the drive control section includes a current detection section for detecting a current flowing through the organic light emitting panel, and the drive control section is capable of judging degradation of the at least one vehicle warning image based on the current detected at the current detection section, and executing a pixel displacement, a first axis displacement, or a second axis displacement of the at least one vehicle warning image or changing a luminance of the at least one vehicle warning image when the at least one vehicle warning image is judged to be degraded. On the other hand, when the at least one vehicle warning image is determined to be degraded, the drive control unit can perform degradation determination based on the shape of the at least one vehicle warning image and perform degradation compensation corresponding to the shape of the at least one vehicle warning image. On the other hand, when the at least one vehicle warning image is determined to be degraded, the drive control unit can perform degradation determination based on the pixels of the at least one vehicle warning image and can perform degradation compensation
