Abstract: AN0052 8-bit LCD controller un-expected image issue Aug. 15, 2008 For GPL0X/GPLXX/GPL61_191_121/GPLB 8-bit LCD Controller Un-expected Image Issue INTRODUCTION It is recommended not to continuously update the same LCD data too frequently; Fail to do so will result un-expected image displaying on LCD in a short time and immediately disappearing after. Therefore, user should update LCD , controllers, such as GPL0X / GPLXX / GPL61/191/121 / GPLB series. ANALYSIS When continuously updating the Generalplus Technology
