* @brief Clears the display.
*
* The display is also cleared by the driver before displaying the newly given string.
* So it is not required for the application to use this API to clear the measurement
* display before displaying the new string. This API can be useful to turn off the display.
*
* @param[in] hDevice Device handle obtained from adi_LCD_Init().
* @param[in] Screen LCD screen on which to clear the mesurement display.
*
* @return Status
* - #ADI_LCDVIM828_ERR_BAD_DEVICE_HANDLE [D] Invalid device handle parameter.
* - #ADI_LCDVIM828_ERR_NOT_INITIALIZED [D] Device has not been previously configured for use.
* - #ADI_LCDVIM828_SUCCESS Call completed successfully.
