I am learning Magento module development. I am trying to develop a custom module for Magento Admin panel. I would like to display grid. My codes are as follows

$this->_headerText = Mage::helper('digitab_brandlogo')->__('Brand Logo Manager');

parent::__construct();
}
protected function _prepareLayout()
{

Error I found in exception.log is as like below
exception 'Mage_Core_Exception' with message 'Invalid block type: Digitab_Brandlogo_Block_Brandlogo' in /home3/theaid/public_html/demo/app/Mage.php:595
I am getting a blank white page when I am clicking on Brandlogo menu of Digitab.
Could anyone help me to display a grid??
Thanks
